Flex Socket Adapters

Pivot the head to access fasteners from an angle.

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.
