1/4-20 x 1/2 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert provides a broad bearing face and smooth exposed dome for thin covers or frequently handled surfaces. 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. This size is often reviewed for cleaning-cycle equipment, stainless guards, and fixture hardware when stainless material, a button head, and a locking pellet are all specified.

Slight magnetism from cold working can be normal for 18-8 stainless, so final selection should reflect the mating parts and environmental exposure. For higher preload potential with a deeper socket, compare 18-8 Socket Head Cap Screws with Nylon Insert. Since 1962, Cold Headers has helped industrial buyers locate specialty socket products for production, repair, and replacement requirements.
