McMaster 5347A127 Changeable-Head Torque Wrench Adjustable, 4 N-M to 20 N-M Torque Range

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.
