About Torque Tools

Changeable-Head Torque Wrenches

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.

Adjustable handles let you set your desired torque. Turn the grip to set and lock the torque value. To relieve pressure on the spring and maintain calibration, set torque to lowest reading on the scale when not in use. Note: Accuracy ratings do not apply to the lower 20% of the torque range.

Factory-set handles are set to a specific value, ensuring the same torque is reached every time. Use adjustment keys (sold separately) to change the torque of these wrenches.

Torque-Limiting Pipe Wrenches

Turn the end of the handle to set torque, and the wrench makes an audible click when it reaches the setting. These tools come with a calibration certificate that is traceable to JIS and includes the test measurements that confirm accuracy.

Note: Accuracy rating applies to the entire torque range.

Torque-Limiting Drum Plug Wrenches

When the set torque is reached, these wrenches slip to disengage and stop turning the plug, preventing overtightening. Also known as bung wrenches, they are used to install and remove screw-in drum plugs.

Calibration certificate traceable to NIST states the product has passed a test for accuracy.
