5/16-18 x 1 1/4 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.
The low-dome head is not a countersunk style; seating and clearance should be checked against the mating surface and surrounding equipment. 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.
18-8 stainless is practical for washdown-adjacent machinery, packaging equipment, and outdoor or high-touch hardware where the service environment is not chloride-critical. For chloride-heavy or saltwater-adjacent service, 316 stainless with nylon insert is a non-catalog request Cold Headers can quote. Nylon inserts are installed in-house at the Chicago facility for supported cap-screw configurations.
