2 inch length Machine Keys

Machine Keys, or Straight keys are made from hardened rod with a machined square or rectangular cross section, and are the most common type of key. They are installed into keyways to transmit torque from shafts to gears and other components. They are called “keys” because they lock a component to the shaft by means of a corresponding keyway in a shaft.
