Description
Overview:
UNF HT Setscrews Grade 'S' are high-tensile, fine-thread hex head fasteners for secure assembly in construction and garden machinery. Manufactured from high tensile steel with a zinc-plated, silver finish, they resist corrosion in outdoor and workshop environments. This size is 5/16 in x 3 in (7.94 mm x 76.2 mm) with UNF 5/16-24 threading, ideal for applications that need strong clamping force and better resistance to loosening under vibration when used with matching UNF nuts or tapped holes. Supplied in a pack of 100, these set screws are suitable for equipment assembly, repairs, and routine maintenance on items such as mowers, compactors, mixers, generators, and general fabrications. Supplied under MPN 903 0113 for easy identification in stores and on job sites.
Key Features:
- Size: 5/16 in x 3 in (7.94 mm x 76.2 mm) for common machinery fixings
