1/4-28 x 1 1/2 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert combines the familiar socket head profile with a nylon insert for added loosening resistance. Nylon contact at the thread adds frictional resistance while preserving the standard internal hex drive arrangement.

This size is often reviewed for automation equipment, robotic end-of-arm tooling, and stainless brackets when a stainless cap screw must retain a familiar socket head form. The nylon element gives the joint a locking feature, but it also limits service temperature compared with an all-metal socket screw.

For torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. Since 1962, Cold Headers has helped buyers locate specialty socket fasteners for production, repair, and distributor requirements.
