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.

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench. When the set torque is reached, these wrenches indicate with an audible click and a momentary release. To reverse torque-limiting direction, remove head, turn handle over, and reattach head. The handle and head combination you choose may have different maximum torque values. Do not exceed the lower value.

Ratcheting square drive head allows you to turn fasteners in tight spaces without removing and repositioning the tool.

Turn the fittings on welding tanks.
