Feather Keys

Feather Keys are drive keys that transmit torque from a shaft to a driven component. They are square keys but with radiused ends. The mating slot in the shaft is machined with an end mill that matches the radius of the shaft key design. Once installed the key is contained in the machined pocket and cannot move axially. It is not necessary to have a set screw hold the key in position. Our White Paper Feather Keys explains the advantage of the feather shaft key design in detail.
