For drawings calling out a nylon insert socket cap screw, the 1/2-20 x 5 1960 Series Alloy Steel Socket Head Cap Screw with Nylon Insert provides exact thread-and-length identification. The nylon insert helps resist loosening through friction at the mating threads, providing prevailing torque without changing the socket head geometry.
Common uses include automation equipment, robotic tooling, and fixture plates, where a precise socket head fastener with added loosening resistance can simplify maintenance and replacement planning. Engineers should confirm that the selected size, nylon insert position, and mating threads suit the assembly before substituting from a standard socket cap screw.
Since 1962, Cold Headers has helped industrial buyers source specialty socket products, unusual lengths, and replacement configurations.
