47286 Allenhead set screw 5/16-18 x 1 1/2 inch

This Gardner-Westcott Allenhead set screw is designed for mechanical assemblies on Harley-Davidson motorcycles where a flush-mounted fastener is required. Measuring 5/16-18 with a 1 1/2 inch length, these screws are manufactured from plain steel, providing a raw finish ideal for internal engine or transmission components where a decorative coating is unnecessary. The internal hex drive allows for precise torque application, ensuring that pulleys, gears, or shafts remain securely locked against rotation. Gardner-Westcott specializes in American-standard hardware specifically for the V-twin market, ensuring these fasteners withstand the vibration and heat cycles typical of air-cooled engines. These set screws are sold in packs of 5 for workshop convenience.
