8-32 x 5/8 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. Slight magnetism from cold working can be normal for 18-8 stainless, so selection should reflect the actual assembly environment and mating hardware.

Use the exact thread, length, pellet diameter, and pellet location when matching drawings or service records. Cold Headers installs nylon inserts in-house for supported socket-cap configurations, with odd-size sourcing handled through the quote process.
