5/8-11 x 2 1/4 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 electrical enclosures, cabinet hardware, or field service assemblies, the internal hex drive keeps installation compact while the insert adds thread-friction locking action. Because 18-8 is not heat-treated for maximum clamp load, compare the 1960 Series Alloy Steel SHCS with Nylon Insert when joint strength is the governing requirement.
For torque-once joints where a locking pellet is not required, plain 18-8 Socket Head Cap Screws may be the simpler routing. Need the pellet in a non-catalog size or position? In-house pelletizing gives Cold Headers a practical route for special requests.
