Changeable-Head Torque Wrenches

Change heads to use these tools as an open-end, box, square drive, or hex-key wrench. The handle and head combination you choose may have different maximum torque values. Do not exceed the lower value. The handles come with a calibration certificate, which includes test measurements that confirm accuracy.

You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

Repair Kits

Ratcheting—Ratcheting square drive heads allow you to turn fasteners in tight spaces without removing and repositioning the tool.

Repair Kits—Include the components needed to replace a damaged ratcheting mechanism.
