Box-End Tight-Clearance Offset Sockets

Make maximum contact on all sides of a fastener to reduce slipping. Often used with an extension, these sockets turn fasteners and fittings in obstructed areas that regular sockets can't reach. They are also known as torque adapters.

Adjustable Torque-Limiting Socket Adapters


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.

Torque-and-Angle Measuring Socket Adapters

A digital display shows how torque measurements change as you turn the wrench. Set the desired torque or 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 scredrivers 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.
