1/2-13 x 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. Its locking element supports service where a standard all-metal cap screw may need an added thread-locking feature.

This size is often reviewed for pump skids, utility frames, and serviceable covers 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.

Use the exact thread, length, pellet diameter, and pellet location when matching drawings or service records. Since 1962, Cold Headers has helped buyers locate specialty socket fasteners for production, repair, and distributor requirements.
