    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.

    4-Pin

    For easy tightening and loosening, these sockets have pins that grip the slotted sides on bearing nuts. These sockets require less clearance around bearings than standard hook spanner wrenches, so they’re good in tight spaces. Use them with a square-drive wrench handle or a ratchet wrench; they’re not for use with impact wrenches.

    Reach nuts obstructed by a fluid line or other barrier with these wrench heads. Connect them to your socket extension and ratchet wrench to turn fasteners where clearance is limited from both the top and side. You can also attach one directly to your ratchet wrench to convert it into an open-ended ratcheting wrench. Also known as crowfoot wrenches.
