3/8-16 x 3 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is a stainless socket cap screw for assemblies that combine cleaning exposure with motion or vibration. 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.

For rounded exposed heads with the same locking concept, review 18-8 Button Head Socket Cap Screws with Nylon Insert. For non-catalog pellet positions or unusual sizes, in-house pelletizing at the Chicago facility gives Cold Headers added sourcing flexibility.
