5/16-18 x 1 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.
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 cleaning-cycle equipment, stainless guards, and fixture hardware when stainless material, a button head, and a locking pellet are all specified.
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 flush countersunk installation instead of a dome head, review 18-8 Flat Head Cap Screws with Nylon Insert. Since 1962, Cold Headers has helped industrial buyers locate specialty socket products for production, repair, and replacement requirements.
