Torque-and-Angle Measuring Socket Adapters

A digital display shows how torque measurements change as you turn the wrench. Set the desired torque and angle—lights and an audible alarm indicate when target has been reached or exceeded.

Note: The accuracy ratings do not apply to the lower 10% of the torque range.

Torque-Measuring Bit Adapters

Eliminate the need for multiple bulky tools with these bit adapters. At less than 3 inches long, these compact adapters convert _1/4" bit screwdriver handles and _1/4" bits into torque screwdrivers so you can fasten to a specific torque. Insert your drive handle and turn clockwise until the hash marks line up with the torque value you need. Not for use with power tools.
