Technical Features
- Square-end profile: Both ends of the key are cut square, allowing flush seating within keyways and enabling use in blind or through-keyway configurations.
- 5/16 in x 5/16 in square cross section: Uniform width and height ensure consistent contact across the full keyway width, distributing rotational load evenly between shaft and hub.
- 3 in length: Provides sufficient engagement length for deeper hub assemblies or applications where extended torque transfer is required.
Applications
- Securing pulleys, sprockets, gears, and couplings to drive shafts in mechanical power transmission assemblies.
- Replacement or repair of existing 5/16 in keyway fits on shafts and hubs in industrial and general-purpose machinery.
- Use wherever a standard square machine key conforming to 5/16 in keyway dimensions is specified.
