Professional Applications & Engineering Value

This 7/16"-14 UNC steel set screw delivers critical fastening reliability in demanding industrial applications where vibration resistance and permanent positioning are essential. The coarse thread profile provides superior grip in soft materials and castings, while the cup tip design concentrates clamping force to prevent rotational slippage in shafts, collars, and pulleys. Manufactured from hardened steel with Rockwell B80 hardness, it maintains thread integrity under repeated adjustments. The external square drive offers excellent torque transmission for high-tension applications in machinery, automotive, and heavy equipment assembly, ensuring secure component locking without strip-out concerns.
