Description
Overview:
These 5/16" UNF x 1" Zinc Plated 8.8 High Tensile Setscrews are fully threaded inch-series fixings for reliable clamping across machinery, vehicles, and structures. Made from high tensile steel (property class 8.8) with a bright zinc plated finish for corrosion protection, they suit both indoor and outdoor use. The 5/16" (7.94 mm) UNF fine thread provides firm engagement and consistent torque, while the 1" (25.4 mm) length covers many common bracket, guard, and panel fixings. Supplied in a bulk pack of 200 under MPN 903 0109, these setscrews comply with ANSI B18.2.1 (1965) dimensional standards. Use them across construction plant, garden machinery, generators, pumps, compressors, trailers, and workshop fixtures where a durable, corrosion‐resistant, fully threaded UNF set screw is required. Alternate code: 9030109.
