Pivot the head to access fasteners in tight spots. These wrenches have a ratchet mechanism that allows you to turn fasteners without removing and repositioning. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.

Made of beryllium copper, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present. Set the desired torque and the wrench indicates when it's reached with an audible click. To relieve pressure on the spring and maintain calibration, set torque to the lowest reading on the scale when not in use.

Note: Accuracy ratings apply to the entire torque range.

Warning: Do not use these tools in direct contact with acetylene.

Pivot the head to access fasteners in tight spots. Set the torque and these wrenches will indicate when it’s reached with an audible click and an impulse in the grip.

Wrenches with a 1/2” square drive size meet ISO 6789 international calibration standards as well as ASME B107.300 safety standards for manual torque-measuring tools. To relieve pressure on the spring and maintain calibration, set these wrenches to 20% of the maximum torque when not in use.

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

Measure with an accuracy of ±2.0%. These wrenches display torque as it’s measured and the maximum torque reached. Use to determine fastener torque specifications as well as to identify the torque required to loosen tightened fasteners. To fasten to a specific value, set the desired torque—lights and an audible alarm indicate when target has been reached or exceeded. Wrenches 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.

Reach the same torque every time with factory-set wrenches that indicate with an audible click and an impulse in the grip when set torque is reached. Wrenches come with a calibration certificate traceable to NIST that states the product has passed a test for accuracy.

Change the torque of these wrenches with adjustment keys (sold separately).

Use these wrenches with impact sockets only. Some wrenches include batteries and a charger. For others, batteries and chargers are sold separately.

Pin-style socket retainer (also called positive locking) has a pin that fits into a matching hole in the socket and provides a more secure hold than ring-style retainers.

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.

Ring-style socket retainer allows quick socket changes—pull the socket off the retainer and push on another one.
