5/16-24 x 1 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 pellet presses against the mating thread to provide prevailing torque without changing the socket head geometry.
In food-processing frames, sanitation-adjacent machinery, or equipment covers, 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 countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Cold Headers installs nylon inserts in-house for supported socket-cap configurations, with odd-size sourcing handled through the quote process.
