About Torque Tools

Socket Adapter

Pin Kit

To set torque, remove the snap ring and locking plate and adjust the nut. When the torque setting is reached, the adapter clicks and releases. These tools let you accurately measure or limit the torque you apply to prevent overtightening and damaging fasteners.

Use clockwise and counterclockwise adapters to tighten fasteners in both directions. You’ll need to change tools to loosen the fasteners.

Use clockwise adapters to tighten fasteners in the clockwise direction as well as loosen them in the counterclockwise direction. There’s no need to change 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.
