INOX 304 hex flange pit screws
Available
INOX Hex Flange Pit Screw T17 A2 (304) is a self-tapping screw. The Hex Flange Pit Screw T17 A2 (304) is a hex head screw with an integral flange and a Type 17 (T17) point, a "pit" screw with a 5/16" drive.
Made from 304 (A2) stainless steel, a standard austenitic grade with good everyday corrosion resistance. It is a sound choice away from the coast; in chloride-exposed settings, step up to 316 (A4). Each variant is supplied in packs of 500. Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.
