1/4-20 x 1 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert fits stainless equipment designs that need a smooth head and controlled thread friction. The nylon element supports repeated service planning better than adhesive-style locking in many maintenance settings, though suitability depends on the actual joint.

The low-dome head is not a countersunk style; seating and clearance should be checked against the mating surface and surrounding equipment. This size is often reviewed for beverage-line equipment, guarding rails, and inspection covers when stainless material, a button head, and a locking pellet are all specified.

The nylon element limits service temperature compared with an all-metal screw; no numeric service limit is implied by this listing. If strength matters more than stainless material, Alloy Steel Button Head Socket Cap Screws with Nylon Insert may be the better route. Nylon inserts are installed in-house at the Chicago facility for supported cap-screw configurations.
