3/8-16 x 3/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is selected when stainless hardware and thread-friction locking are needed in the same fastener. The pellet presses against the mating thread to provide prevailing torque without changing the socket head geometry.
In HVAC equipment in humid plants, damper hardware, or service panels, the internal hex drive keeps installation compact while the insert adds thread-friction locking action. The 18% chromium and 8% nickel austenitic stainless material is used for general corrosion resistance and a clean appearance in ordinary industrial environments.
Use the exact thread, length, pellet diameter, and pellet location when matching drawings or service records. 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.
