Impact Hex Bit Sockets


	For Hex Drives

These sockets are made to withstand the high torque and force of impact tools.

Compatible Retaining Ring ID—Sockets that list a compatible retaining ring ID 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.

Replacement Socket Bits for Hex Bit Sockets

Switch out worn or damaged bits instead of replacing your entire bit socket. No need for set screws or roll pins to keep these bits in place—they have nylon pellets at their base that compress within the socket for a snug fit. Tap them into hex bit sockets with a hammer. They flex slightly to withstand the high torque and force of impact tools. They can also be used with hand-drive tools.

Changeable-Head Torque Wrenches

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench. The handle and head combination you choose may have different maximum torque values. Do not exceed the lower value. The handles come with a calibration certificate, which includes test measurements that confirm accuracy.

You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

Cordless Impact Wrenches


Pistol Grip	Ring Socket Retainer

Loosen stuck fasteners and drive in fasteners with high force anywhere on your site. These impact wrenches run on a rechargeable battery, so you don’t need to be near an outlet to use them. Wrenches operate at full torque in the counterclockwise direction. The working torque range applies to the clockwise direction, often used for fastening. Use these wrenches with impact sockets only.

Some wrenches come with batteries and a charger. For others, batteries and chargers are sold separately.

Ring Socket Retainer—Ring-style socket retainers allow quick socket changes—pull the socket off the retainer and push on another one.
