8-32 x 5/8 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert supports stainless fastening in washdown-adjacent machinery without changing button-head geometry. The locking pellet adds a prevailing-torque feature while the internal hex drive keeps installation compact from the top side.

Button head geometry is useful around access covers, machine guards, and operator-contact surfaces where a smooth exposed profile is preferred. For display and fixture hardware, decorative covers, or light-duty brackets, confirm the mating thread, drive access, and whether surface contact from the button head suits the assembly.

The 18% chromium and 8% nickel austenitic stainless material is commonly chosen for general corrosion resistance, clean appearance, and ordinary moisture exposure. Plain 18-8 Button Head Socket Cap Screws may fit torque-once joints where the nylon insert is not required. Nylon inserts are installed in-house at the Chicago facility for supported cap-screw configurations.
