Key features

Product DescriptionHillman Socket Set Screws are headless fasteners built to lock a rotating or sliding part onto a shaft. Sized 1/2-13 x 1/2", they thread through a tapped hole in a collar, gear, pulley, knob, or hub so the point bears firmly against the shaft, holding the part in position and preventing it from slipping or spinning under load. The headless design seats fully below the surface so nothing protrudes to catch or snag, while the internal hex socket drive lets you apply high torque with an Allen key, even in tight or recessed spots. The coarse thread and blunt point grip the shaft securely without heavily marring it, so parts can be repositioned when needed. Machined from steel with a plain, dark finish, these set screws offer the strength to hold firmly under torque and vibration. They are made for dry indoor drivetrains, machinery, and assemblies, standing up to everyday operation and repeated adjustment while keeping parts locked in their set position over time. Use them for fastening pulleys, gears, sprockets, collars, knobs, and levers to shafts in motors, machinery, tools, and equipment. They are a staple for drivetrain assembly, repair, and routine maintenance i
