Square Key Stock, 1/2"

Square Key Stock, 1/2" is a solid steel key stock designed to lock rotating components to shafts, preventing slipping between parts such as gears, pulleys, sprockets, and couplings. With a 1/2" square profile, this key stock fits standard keyways and provides a strong mechanical connection that transfers torque efficiently in machinery and power transmission systems. Made from durable steel, it can be cut to the exact length needed, making it ideal for repairs, fabrication, or equipment maintenance. Available by the inch or by the foot, it’s a versatile shop essential—because sometimes the smallest piece of steel is the one keeping the whole machine turning.
