4-Point Impact Sockets



The square shape provides the best possible grip on square fasteners and prevents rounding. These sockets are made to withstand the high torque and force of impact tools and require a locking retainer. Use 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.

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.
