Our Solutions for the Industrial & Construction Industries

APM Hexseal provides many top-quality sealing products for use in industrial and construction applications. Our large selection of sealing bushings, boots, and self-sealing hardware helps protect electronic and mechanical equipment from environmental contaminants.

Here are some of the quality fasteners that work best in the industrial and construction industries.

Seelskrews® & Seelbolts®

Our selection of patented Seelbolts® and Seelskrews® harnesses the power of both reliable fastening hardware and weatherproof sealing capabilities. The resulting product is a reusable and highly dependable seal that eliminates the need for messy sealing compounds that make projects more challenging and increase the likelihood of leaks and failures.


In addition, we offer our innovative Seelnuts® for use in industrial and construction applications. These sealing nuts hold up in extreme temperatures of 103 °F to 400 °F. These products feature a self-sealing design that provides reliable sealing, easy installation, and wide compatibility with standard screws, bolts, and studs. Seelnuts® can easily be removed and installed elsewhere, providing the same sealing power when torqued.


One of our latest innovations is our Nutzilla – a sealing nut available in sizes up to M90, which uses the same patented metal-to-rubber bonding process as our other sealing nuts. With oversized fasteners, the simpler the design, the better. The Nutzilla is a one-piece, jumbo-sized self-sealing nut that is easy to install and effectively and consistently seals with large bolts while eliminating the need for any additional sealing compounds or gaskets.

Nutzilla is reusable, has a shelf life of over 25 years, and offers high seal integrity. Typical applications are large-scale construction projects such as bridges and tunnels.

Seeloc® Washers

Seeloc® washers provide airtight sealing when used with standard screws, bolts, and studs. One unique feature of these washers is a silicone contact surface with a continuous ridge, which forms a complete seal around the entire washer face under compression. The silicone rubber material seals beneath the head of the fastener while making contact with the threads, allowing for a secure seal even under high pressures.
