47271-25 PACK Allenhead set screw 5/16-24 x 1/2

This 5/16-24 x 1/2 inch Allenhead set screw is manufactured from plain steel, designed for internal mechanical applications where a headless fastener is required to sit flush or below the surface. Typically used on Harley-Davidson motorcycles to secure pulleys, gears, or control knobs to shafts, the fine thread pitch ensures precise tension and resistance to backing out under vibration. Gardner-Westcott provides these high-strength fasteners to meet the rigorous demands of American V-twin assemblies. The plain steel finish is suitable for internal use or areas where the fastener will be lubricated. These set screws are sold in packs of 25.
