Undersized Key Stock

A key stock is a square or flat piece of metal (key) that has been machined to function as a locking torque mechanism, connecting a shaft to a component, such as a gear or pulley. Made of steel bar stock, these key stocks prevent movement between the shaft and component, allowing force to be released without causing machinery stress. We have undersized key stock in many sizes and grades, made in lengths of one foot or greater. Zoro has oval-shaped parallel keys and machine keys too. We also carry oversized key stock, woodruff key stock, and step key stock to help you get more out of your machinery.
