3/8-24 x 5/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert is built for drawings that call for both stainless material and prevailing-torque thread locking. 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.
For countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Need the pellet in a non-catalog size or position? In-house pelletizing gives Cold Headers a practical route for special requests.
