Electronics Division
Since Since 1947, APM Corp. has specialized in the design and manufacture of molded elastomeric rubber seals for environmental protection of electrical controls (toggle switches, pushbutton switches, rotary switches, and rocker switches) for industrial, marine, medical, consumer, and military applications. Most seals, including self-sealing and self-locking panel fasteners, are UL and CSA-Recognized and designed to meet military specifications.

Self-Sealing Fasteners and Washers Division
APM Fastener Division was founded with the mission of providing high-pressure sealing solutions for industry and the military. APM immediately began to develop and patent a wide variety of self-sealing fastening products; self-sealing screws, self-sealing & self-locking bolts, self-sealing rivets, self-sealing locking nuts, and air and water-tight self-sealing washers. Each share a common characteristic of one-piece design with the ability to be reused multiple times.
