5-40 x 7/8 1960 Series Alloy Steel Socket Head Cap Screw with Nylon Insert is a socket-driven cap screw for assemblies that need a built-in prevailing-torque feature. The nylon insert helps resist loosening through friction at the mating threads, providing prevailing torque without changing the socket head geometry.
In machine guards, equipment covers, and service panels, the internal hex drive allows compact tool access while the alloy steel body keeps the product aligned with drawings that specify this material. Selection should account for joint geometry, thread engagement, installation access, and whether a nylon insert is appropriate for the service environment.
Cold Headers provides catalog depth for specialty socket fasteners and helps purchasers identify the correct alloy steel nylon insert configuration.
