Description
This 5/32 x 3/4 in steel Woodruff key from HILLMAN is a small but essential machine component for securing gears, pulleys, sprockets and collars to shafts. Its semi-circular shape fits into a matching hub pocket to provide a reliable shear surface that transmits torque while allowing for easy alignment during assembly. Made of steel with a precision cut finish, it suits light- to medium-duty applications in lawn equipment, engines, transmissions and shop-made drives where a compact, low-profile key is required. Installers and hobbyists will appreciate how the Woodruff design minimizes shaft stress and simplifies seating compared with straight keys, making it handy for repair work, rebuilds, and custom machinery projects.
