About Torque Tools

Round Head

A ratchet mechanism allows you to turn fasteners without removing and repositioning the wrench. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.

Flex-Head Wrench Handles

Pivot the head for access to fasteners in tight spots. Also known as breaker bars, use these nonratcheting handles to get the high torque required to break stuck fasteners free.

Adjustable Torque Wrenches

Ratcheting

Nonratcheting

Set the desired torque and the wrench indicates when it's reached with an audible click and an impulse in the grip. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use. These wrenches come with a calibration certificate that is traceable to NIST or UKAS and includes the test measurements that confirm accuracy.

Note: Accuracy ratings do not apply to the lower 20% of the torque range.

Dial Torque-Measuring Wrenches

A main pointer on the dial shows torque as it’s being applied and a memory pointer indicates the maximum torque reached. Use these wrenches to determine fastener torque specifications as well as to identify the torque required to loosen tightened fasteners. They come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.

Note: Accuracy ratings do not apply to the lower 20% of the torque range.

Standard Duty Air-Powered Impact Wrenches

Ring-and-Hole Style Socket Retainer

Use these wrenches for medium-volume production, general maintenance, and construction applications. Wrenches operate at full torque in both clockwise and counterclockwise direction. Use with impact sockets only. Air-powered tools require lubrication to operate properly.

Pin-, hole-, and ring-and-hole-style socket retainers (also called positive locking) provide a more secure hold than ring-style retainers. Hole- and ring-and-hole-style retainers require a retaining ring.

Light Duty Air-Powered Impact Wrenches

These tools are suitable for general shop, maintenance, and automotive work. Wrenches operate at full torque in both clockwise and counterclockwise direction. Use with impact sockets only. Air-powered tools require lubrication to operate properly.

Ring-and-hole style socket retainer (also called positive locking) provides a more secure hold than ring-style retainers and requires a retaining ring.

Heavy Duty Air-Powered Impact Wrenches

Hole-Style Socket Retainer

Built for durability, these high-performance tools handle the demands of high-volume production and tough maintenance applications. They have a positive-locking socket retainer that provides a secure hold. Wrenches operate at full torque in both clockwise and counterclockwise direction. Use with impact sockets only. Air-powered tools require lubrication to operate properly.

Hole-style socket retainer requires a retaining ring (included).
