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.
