1/2-13 x 3/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert supports compact internal-hex fastening where a backed-out screw would create a service problem. 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.

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.
