3/8-16 x 7/8 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert brings stainless material and a nylon locking pellet to equipment that sees ordinary moisture or cleaning. The nylon pellet presses against the mating thread for prevailing torque without changing the head geometry.
Because the socket is shallower than a full socket head cap screw, compare 18-8 SHCS with Nylon Insert when clamp load and deeper drive engagement govern the joint. In food equipment panels, washdown covers, or stainless frame hardware, the internal hex drive supports top-side installation while the rounded head reduces surface projection.
The nylon element limits service temperature compared with an all-metal screw; no numeric service limit is implied by this listing. For higher preload potential with a deeper socket, compare 18-8 Socket Head Cap Screws with Nylon Insert. Cold Headers installs the locking pellet in-house for supported socket-cap sizes, with odd-size requests handled through quoting.
