Spanner Sockets


Socket Shown With Wrench (Sold Separately)

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.

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.

Spindle Puller Adapter—Spindle puller adapters remove the front spindle on four-wheel drive trucks so you can access the needle bearing when lubricating and aligning the front wheels.

6-Point Rounded: 2 3/8", 2 1/2", 2 9/16", 2 3/4"—6-point rounded sockets fit the special rounded hex nuts found on some trucks.

Plastic Case—Carry sets with a plastic case from one location to the next.

4-Pin Socket and 6-Pin Socket—4-pin and 6-pin sockets fit around retaining locknuts with slots or holes in the side. Also known as spanner sockets, they’re similar to tri-groove sockets but have four or six pins instead of three.

6-Point Socket—6-point sockets are designed for use with hex locknuts.

6-Point Lug Nut-Holding Impact Sockets

Move from lug nut to lug nut with the speed of a racecar pit crew. Up to five standard 6-point lug nuts stack up in the shank of these sockets, so you don’t have to stop to take the lug nuts out of the socket. With thicker walls and more give than standard sockets, these sockets can withstand the high torque and force of impact tools.

Retaining Rings

Remove and install dual wheels on trucks and trailers with the sockets in these sets. The sockets are extra deep for use with Budd wheels, so you can remove both the nut and the stud with a single socket. Sets include sockets for hex drives to access lug nuts and sockets for square drives to turn the threaded shafts on inner wheels. All are impact sockets, made to withstand the high torque and force of impact tools. Use them with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring-style socket retainer.
