    Wheel Bearing Locknut Socket Sets

    Shaped and sized for compatibility with wheel bearing locknuts on trucks and trailers, the sockets in these sets make it easy to install and remove locknuts. They ensure the proper torque setting when you reinstall a locknut on your wheel, so you know it's safe and secure. These are square drive sockets for use with hand-driven tools, not impact wrenches. Made of steel, they grip locknuts tightly and prevent rounding.
