3/8-16 x 2 3/4 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert fits replacement and production work where the exact stainless size and pellet feature matter. The insert is positioned in the threaded body so the screw can develop prevailing torque during engagement.

In outdoor control enclosures, panel hardware, or instrument mounting brackets, the internal hex drive keeps installation compact while the insert adds thread-friction locking action. 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. Cold Headers supports industrial maintenance and OEM sourcing teams when difficult-to-find stainless socket products are specified. The 1960 Series name identifies the modern ASME B18.3 head-proportion standard for socket head cap screws, successor to the older 1936 series, not a year of manufacture.
