  2. Is a Gasket the Same as a Washer?

    Leave a Comment

    APM Hexseal is a leading provider of durable high-quality sealing hardware, including custom-molded gaskets and washers. Gaskets and washers are often assumed to be the same thing, as they have a similar design and are both used in conjunction with other components. While they have a similar appearance, they serve very different purposes.

    APM Hexseal Seeloc WasheGasket vs. Washer: What’s the Difference?

    Although gaskets and washers share some similarities, they serve different functions. Gaskets are used to prevent leaks around mating surfaces, whereas washers are used to distribute the load of a threaded fastener. Most washers won’t have the ability to prevent fluid or gas leakage; therefore, gaskets are the better choice for sealing applications. 

    The shape and size of washers are also different compared to gaskets. Most washers are small and feature a uniform circular shape to enable them to fit around bolts. Gaskets are not used with bolts, meaning they are available in a wider variety of shapes and sizes. In terms of materials, washers are almost always made of metal; whereas gaskets can be made of metals, metal alloys, rubber, and other materials.

    Common types of gaskets include:

    • Flange gaskets
    • Constant seating gaskets
    • Spiral-wound gaskets
    • Soft-cut gaskets

    Common types of washers include:

    • Plain washers
    • Locking washers
    • Spring washers
    • Torque washers

  3. The Purpose of Washers & Why They’re Used With Fasteners

    Leave a Comment

    A washer is a mechanical component that consists of a circular flattened metal, plastic, or rubber disk with a hole through the middle. Washers are typically used with fasteners such as screws and bolts to distribute the load of the fastener, prevent damage to sensitive surface materials, and reduce the potential for leaks. Are washers necessary? That depends largely on the application and the substrate. 

    For more than 70 years, APM Hexseal has been creating innovative sealing solutions for customers in every industry. We leverage our extensive knowledge and hands-on experience to create cutting-edge sealing fasteners that meet the most rigorous expectations. In this article, we discuss the purpose of washers and their uses with fasteners.

    The Purpose of Washers

    APM Hexseal Seeloc WasheFasteners join two or more surfaces together through the use of threaded screws or bolts. Washers are incorporated into fastening hardware for everything from wooden furniture to automotive engines. 

    How Do Washers Work With Bolts?

    To enhance fastener performance, a washer is placed on the bolt or screw between the head and the mating surface. In some applications, washers may also be placed between the nut and object surface. 

    What is the Purpose of a Washer?

    Since not all applications require them, it can be difficult to determine when to use washers. Washers serve a variety of purposes, including: 

    • Load Distribution: Fasteners exert high levels of force when installed. Washers help to distribute that load to prevent damage to the material. Without washers, materials are more likely to crack due to tightening pressure.
    • Spacing: If the length of the bolt or screw is greater than the object’s thickness, it is impossible to sufficiently tighten the fastener without the screw protruding from the other side. By adding washers, you can create enough space to prevent the fastener from going too far into the substrate.
    • Absorbing Vibrations: Washers made from plastic or rubber absorb vibrations in high vibration applications. Vibration reduction keeps the fasteners from loosening over time and helps to protect the attached equipment from vibration damage.
    • Sealing Connections: Washers can be used to seal joints on piping, tubing, and ductwork, to create a waterproof seal that prevents gas or fluid leakage. 

    Why Washers Are Used With Fasteners

    To determine whether a washer is appropriate for your application, it is important to know how washers work with bolts, screws, and other fasteners. 

    • Washers Divide Weight: When you add a washer, the force exerted by the fastener is spread out over a larger area, reducing the potential for cracks due to pressure and stress.
    • Washers Enhance Space: Washers help to ensure that the bolts and screws fit snugly. By threading the fastener through the washer before installation, you ensure that the fastener doesn’t go too deeply into the surface material.
    • Vibration Reduction: Vibration isolation washers are manufactured using soft vibration-absorbent materials like rubber or plastic. They help to absorb vibration, reducing the amount of stress applied to the fastener and surrounding equipment. 
    • Leak Protection: By creating an airtight, watertight seal, washers can prevent liquid from leaking around the drilled fastener holes in plumbing and process piping and connections.

    Seeloc Washers From APM Hexseal

    Using the latest technology, APM Hexseal has created a washer that provides all of the benefits of traditional washer materials in one convenient package. Our state-of-the-art Seeloc® washers consist of strong, corrosion-resistant stainless steel bonded to flexible silicone rubber, for a soft yet durable sealing and fastening solution.

  4. Common Causes of Metal Roof Leaks

    Leave a Comment

    Metal roof leaks are not unusual, but they can be extremely costly. Undetected and unchecked, a leak can allow moisture to collect on roof supports, interior walls and ceilings, and even structural supports that keep the building standing. Over time, moisture can cause these building components to rust or rot. Standing water in the building interior can also promote microbial growth, which can cause severe air quality issues and health problems. 

    Metal Roof LeakAt APM Hexseal, we understand that an impenetrable metal roof is critical for keeping your building protected from moisture. Our sealing products are specifically designed to withstand the extreme conditions and corrosion that are common in outdoor roofing applications. In this article, we discuss common causes of metal roof leaks, how to fix them, and ways to prevent future leaks.

    Common Problems of Metal Roof Leaks

    The most common cause of metal roof leaks is the roofing screws used to attach the panels to the frame of the building. The screw design, installation method, and angle can all affect the way that the roof performs over time. Metal roofing screws create a hole in the roof, but generally do not seal the opening. Even when a sealant is used, screws that are under-driven, over-driven, or installed at the wrong angle all present opportunities for moisture to leak under the metal paneling. 

    In addition to poor screw design and installation, other causes of metal roof leaks include: 

    • Faulty Screws: Poorly performing screws with misaligned threads or breakage can create an opening in metal roofing. Over time, rubber washers degrade and lose their sealing properties.
    • Missing Sealants: Quality metal roofing installations include sealing hardware or liquid sealants that prevent leakage from screw holes, panel seams, and other vulnerable points. These sealants must be replaced over time due to environmental wear.
    • Overlapping Seams: If your metal roofing is not installed flush, the overlapping seams can create a space for liquid to pool and leak into the interior of the building.
    • Stack and Curb Flashings: Flashings are plastic sheets just under the exterior roof and walls of a building or the rubber boots that surround extruding pipes. They are used to prevent moisture from entering the interior of the building. Poorly installed or missing flashing can result in damaging moisture leaks if the exterior is not sufficiently sealed.
    • Misplaced Screws: In some cases, stray screws used for wood framing or struts may miss the mark and pierce the roof, creating an unexpected hole that can easily be overlooked. 

    How to Fix the Leak in Your Metal Roof

    After installing a metal roof, it is critical to double-check your work to ensure all screws are properly installed. If your metal roof screws are leaking, it is important to take care of the issue as quickly as possible. Sealing metal roof leaks around screws with an external sealant may temporarily fix the issue, but surface sealant wears off over time. Instead, opt for sealing hardware such as APM Hexseal’s Seelskrews, Seelbolts, Seelnuts, and Seeloc Washers. Our stainless steel hardware features rubber-bonded threads and surfaces to serve the dual purpose of fastening and sealing. They will automatically seal metal roof leaks around screws without the need for additional sealing hardware or messy liquid sealants. For your installation and construction equipment, we also provide metal-to-rubber bonded washers, sealing boots, and bushing seals to protect your equipment controls.

  5. Why Use Sealing Hardware?

    Leave a Comment

    Sealing HardwareIn the industrial sector, sealing hardware plays a critical role in ensuring components are securely fastened within a system and preventing contaminants—such as liquids and gases—from moving through the sealed area. Depending on the type of hardware—e.g., screws, nuts, bolts, and washers—and design employed, industry professionals can also take advantage of additional functions and features.

    The following blog post provides an overview of some of the benefits of using sealing hardware, as well as outlines the types of sealing hardware available at APM Hexseal.

    Benefits of Using Sealing Hardware

    When exposed to variable internal and external pressures and high vibration levels, fasteners in fluid systems can experience improper or inadequate sealing that leads to the leakage of process fluid and loss of pressure. These effects, in turn, affect the integrity and efficiency of the process and the performance and stability of the system—ultimately leading to lower productivity, greater downtime, and larger investments into maintenance and repair operations.

    For situations where regular fasteners are unable to prevent the unintentional flow of fluids, sealing hardware serves as an excellent solution. The specialized fasteners are designed to contain and prevent contaminants, such as air, dust, water, and lubricants, from leaking out of or into sealed areas of a system. In addition to this primary purpose, specific types of sealing hardware may also perform other functions. For example:

    • Sealing screws and bolts, such as Seelskrews® and Seelbolts®, can be designed to perform in environments regularly exposed to high levels of vibrations and impact
    • Sealing nuts, such as Seelnuts®, can feature designs capable of withstanding significant internal and external pressures
    • Sealing washers, such as Seeloc® washers, are available in heavy-duty variations that endure higher torque values without experiencing excessive damage or wear

    Regardless of the type of sealing hardware employed, ensuring it performs its critical function necessitates choosing the right solution for the system. Proper selection entails considering several factors regarding the particular system—such as process fluids and operating pressures and temperatures—and sourcing quality products from a reputable supplier. Fortunately, APM Hexseal offers several sealing solutions suitable for use in a wide range of operating conditions. 

    Sealing Hardware From APM Hexseal

    APM Hexseal Sealing HardwareAt APM Hexseal, we understand that our customers often need more than a fastener for their industrial equipment.

As the first designer and manufacturer of self-sealing fasteners, we offer a number of patented solutions, including:

    • Seelskrews and Seelbolts. Our proprietary hardware is specially designed to withstand high vibrations and repeated impact—serving as reliable seals against liquids and gases—including in applications that involve constant vigorous motion.
    • Seelnuts. These hardware components are particularly useful for equipment exposed to exceptional internal or external pressures, such as hydraulic and pneumatic systems. They feature threads molded directly into the rubber of the interior surface, a design that allows them to form a positive seal between the threaded section and the contact surface. Their exceptional sealing ability eliminates the need for gaskets, sealing compounds, or other sealing components, thereby reducing the overall cost of hardware for the system. In addition, their superior performance saves both time and money on repairs and downtime. These qualities result in more reliable and cost-effective equipment. They are compatible with conventional fasteners like screws, bolts, and studs.
    • Seeloc® Washers. Our self-sealing stainless steel washers are bonded on one side with silicone rubber, enabling them to endure pressures up to 100psi.
    • Heavy-duty Seeloc washers. Our new line of heavy-duty washers withstands torque values at least 50% greater than our original Seeloc Washers. Wear and pressure resistance at this level reduce the need for frequent maintenance and repairs on high-powered equipment.

    Susanna Morse

    November’s recipient of the NextGen for Industry Award is Susanna Morse, the Director of Engineering and Technology at APM Hexseal, a third-generation family owned business. Although she’s leading the company forward, it wasn’t her original career path.

    Instead, her parents approached her after they were both diagnosed with cancer. They told her they’d probably have to sell the business—which was started by Susanna’s grandparents—unless she wanted to get involved. She made the decision to leave the fitness studio she had been running for eight years and join APM Hexseal—which she did with a 100% commitment.

    That’s not to say it has been an easy journey. Many of the employees had been with APM Hexseal for a long time and they were happy with the way things were. As Susanna says, “Change is hard. People get so comfortable with what they’re accustomed to that sometimes you walk in and wonder how they haven’t realized there are newer, more effective ways to accomplish their goals.”

    With Susanna’s vision, leadership, and collaborative nature, she’s been able to create the necessary changes within the company to prepare us for continued growth.

    Positive Change at APM Hexseal

    Susanna joined a multi-generational team at APM Hexseal, complete with a variety of opinions and levels of comfort regarding how the business operated. By creating an environment of innovation and collaboration, she made the changes she saw necessary if APM Hexseal was to continue to be a successful player in the sealing industry. Instead of trying to do everything at once, she made small, incremental changes—one or two at a time—as her team began to see her vision and trust her leadership.

    From the beginning, she focused on diversifying the company—a focus that goes back to her grandmother, Riva Morse, who co-founded the company with Susanna’s grandfather, Milton. Riva was the original leader of the sales department at APM Hexseal, a role that was not typically held by a woman in this industry at that time.

    That spirit of diversity and a willingness to do things differently were built into the company’s foundation, and Morse is proudly continuing that tradition. In a traditionally male-dominated manufacturing industry, she has encouraged female employees to take on key responsibilities in the organization.  

    Susanna has also worked to update the company’s technology and bring on younger employees as she fosters collaboration between generations and levels of management. She’s carefully balancing the company’s roots while challenging industry norms and staying competitive in today’s ever-changing market, while pursuing APM Hexseals primary objective – Ever Better. 

    It’s no simple task, but it’s a recipe for success that APM Hexseal can rely on. Congratulations to Susanna on receiving this well-deserved recognition!

  7. Benefits of Cold Headed Fasteners

    Leave a Comment

    What Are Cold Headed Parts?

    Cold heading is a manufacturing method that employs cold forming techniques to produce standard and custom fasteners and components quickly and efficiently. Parts and products produced through this method are referred to as “cold headed”.

    The cold heading process involves the use of a cold heading machine that contains a series of specialized hammers and dies. Pre-cut wire—also known as a slug—is inserted into the machine, where the hammers and dies form it into the desired part shape. As the name suggests, no heat is required for cold heading operations, and all of the part shaping can be done on cold metal.

    Some of the key characteristics of the cold heading process include:

    • Little to no material waste.The initial slug is cut to approximately the same volume as the end product, and the forming process is performed by a die rather than by cutting the raw material into the desired shape and form. These process qualities allow virtually all of the raw material to consumed in the shaping process.
    • Versatility. Cold heading can be used to produce a variety of parts and products, ranging from small fasteners (such as screws, shoulders, lugs, and washers) to larger metal components.
    • Reduced production cost.  The cold heading process is much more cost effective than the machining process, making it an attractive economic solution.

    Solutions for Enhanced Performance

    Compared to fasteners formed through other manufacturing methods, cold headed fasteners offer superior performance. This characteristic stems largely from the rearrangement of the raw material’s grain structure that occurs during the cold heading process. This alteration of the material results in end products that demonstrate greater durability and tensile strength.

    Sealing hardware that is produced through cold heading methods also exhibit enhanced sealing capabilities. At APM Hexseal, our sealing screws are cold headed to ensure they protect sensitive equipment from external contaminants.

    Advantages of Using Cold Headed Fasteners

    Using the cold heading process to form fasteners offers a number of advantages, including:

    • Less material waste. As discussed previously, cold heading produces little to no material waste. In practice, this translates to significant material savings ranging from up to 60–70%.
    • Greater tensile strength. Due in part to optimized grain flow, cold headed components typically offer a higher degree of tensile strength than parts produced through other manufacturing methods. This process quality allows for the manufacture of more durable and reliable parts and products.
    • Better production efficiency. Cold heading allows for faster production speeds, making it suitable for high volume production runs. Additionally, the process enables manufacturers to consolidate multi-part assemblies into single-part units, which can result in significant material, labor, and production savings.
    • Broader design versatility. Cold heading accommodates designs of all shapes, sizes, and complexities. Depending on the dies used, even highly complex geometries can be produced to extremely tight tolerances.

With seven decades of experience under our belt, we have unparalleled ability and knowledge in protecting vital components. In the field of sealing solutions, we lead the pack as the innovator, not just another imitator.

    APM Hexseal’s History as an Innovator

    During WWII, the U.S. military needed a way to protect vital components of electrical equipment in harsh battlefield conditions. Milton Morse, a self-taught engineer, responded with an ingenious solution. He invented a molded covering to protect the switch and the mounting panel from environmental assaults. This component was the original sealing boot and it was a huge success.

    In 1947, Milton Morse and his wife Riva Solins Morse founded APM Hexseal. Their shared mission was to develop and manufacture sealing solutions that would protect circuit breakers and electromechanical switches from environmental damage, prolonging their service lives. Although APM Hexseal originally manufactured these sealing solutions for military use, in time many other industries came to value the protection they provide.

    Of Milton Morse’s many inventions, one of the most commercially successful are his environmental sealing boots for electrical components. This innovative device has produced the majority of his company’s profits. Up til now, more than 50 million boots have been manufactured by APM Hexseal and sold to more than 200,000 customers worldwide.

    Sealing boots are an inexpensive way to protect electrical and electronic switches from damage caused by many different hazardous substances such as water, dust, salt spray, oil, grease, solvents, lubricants and many others. The sealing boots also defend against the elements and other environmental conditions, including snow, wind, sun exposure, and pressure fluctuations from altitude changes.

    The versatility of sealing boots lends the product to use in numerous industries. They have been employed in defense applications, such as aircraft carriers, submarines, Apollo space vehicles, Polaris missiles, and Patriot missile launch controls. Some of the product’s other industrial and commercial applications include use in aircraft, machine tools, pressure washers, waste treatment equipment, chemical processing equipment, and underwater lighting.

    Milton Morse’s career spanned 50 years. He engineered technical solutions that have fueled development in a wide range of commercial, industrial, and military products and systems. His dedication to innovation is demonstrated by the 65 U.S. patents and 39 foreign patents he holds, including awards in Belgium, Canada, France, Great Britain, Italy, Japan, Spain, and Switzerland.

    Milton Morse was still active well into his 80’s. He was even issued a patent as recently as January of 1995. In 1997, to commemorate his technological achievements, he was inducted into the New Jersey Inventors Hall of Fame. Riva remained active into her 90’s and would still visit the office frequently until she passed in 2018, at the age of 100. Today, APM Hexseal remains a Morse Family owned business and proudly carries on Milton and Riva’s visions and legacies.

    Elastomers are the key to providing effective sealing solutions for applications in outdoor, marine, medical and any environment where sealing stuff in or sealing stuff out is imperative. Elastomers are versatile materials typically composed of polymers, and manufacturers prize them for their ability to bend and stretch in a variety of ways before returning to their original shape.

    However, not all elastomers are the same. Elastomers can incorporate a wide range of designs and materials depending on the needs of their intended application. More than 20 different types of standard elastomers exist, and each possesses unique functions in both process equipment and finished products.

    Different elastomer formulations affect the physical properties, functions, and service life of your components and systems. This is why it’s essential to test a few different elastomers to determine the best one for your needs. In this post, we outline ways to evaluate elastomers for their capacity to perform well in your application, and we also describe some of the best uses of each different type of elastomer.

    Questions to Ask When Selecting an Elastomer

    When you’re trying to determine the best kind of elastomer to use for your sealing or fastening application, keep the following few questions in mind:

    • Where and how will the sealing boots or fasteners be used? Applications that use elastomers can appear in many different environments, such as:
      • Outdoor
      • Marine
      • Industrial/manufacturing environments
      • Drilling and downhole
      • Food and beverage (some elastomers have FDA approval; others don’t)
      • Aerospace
      • Construction
      • Medical
    • What kind of contaminants will the sealing boots or fasteners come into contact with?
      • Different elastomers hold up better against specific environmental conditions or contaminants.
    • Will the sealing boots or fasteners experience extreme temperatures or wide temperature fluctuations?
    • Will the elastomer be exposed to sharp objects or coarse surfaces or need to withstand a high number of actuations or repeated human contact?
    • What is your budget compared with the cost of failure?

    Even though many differences exist between the types of elastomers on the market, they all bring unique advantages to injection molding processes and products. The injection molding process forces rubber compounds into a mold using high pressure. Elastomers perform well in this type of environment because they’re made of similar materials as those used in injection molding.

    Compression molding is another area that benefits from the use of elastomers. The compression molding process takes high-viscosity compounds and processes them into a pre-form. It then compresses the pre-form into a mold before curing it.

    Elastomers work well in a variety of hostile environments, such as:

    • Extreme temperatures
    • Corrosive oils and chemicals
    • Food and beverage applications
    • Road salt distribution
    • Dirt, dust, and sand
    • Water
    • Extreme weather
