5/16-18 button head socket cap screws in 18-8 (A2-70) stainless steel to ASME B18.3, fully threaded. A low, domed head (0.547" diameter x 0.166" high) with a 3/16" hex socket: a clean, rounded profile where a standard socket cap would stand too tall, for guards, panels, fixtures and enclosures. UNC coarse thread, threaded the full length. 18-8 (A2-70) stainless resists rust and staining outdoors and in wash-down areas. Chrome plating gives a bright, decorative finish over the stainless. Sold in production-volume bulk packs.
