3/8-16 x 1/2 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert combines stainless material, internal hex drive access, and a nylon locking pellet. When installed in the correct countersink, the flat head leaves little exposed hardware for covers, panels, or moving material to catch. Flat head screw lengths are measured overall, head included, so this listed length is the total installed screw length.
This size is often reviewed for packaging machinery guards, changeover plates, and transfer covers when stainless material, a flush head, and locking friction are all specified. For higher preload potential and a deeper socket, review 1960 Series 18-8 SHCS with Nylon Insert.
The nylon pellet presses against the mating thread to provide prevailing torque without changing the countersunk head geometry. Since 1962, Cold Headers has helped distributors, repair teams, and OEM sourcing projects locate specialty socket products.
