1/4-20 x 1 1/4 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert gives replacement work a specific stainless size with an integral locking pellet. 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. For automation cells, sensor plates, or compact machine panels, confirm the mating thread, drive access, and whether surface contact from the button head suits the assembly.
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. Cold Headers can help confirm the correct 18-8 button head nylon-insert size before quoting pricing and availability.
