The Grey Pneumatic Tork-Socket is a torque limiting tool. When a lugnut is tightened with a Tork-Socket and impact gun, the lugnut stops turning at the specified torque. This is possible because the shaft of the Tork-Socket is made from spring steel and starts to twist when the impact gun tries to over-torque the lugnut. When the hammer inside the impact wrench stops and rotates for the next blow the shaft unwinds, this allows the fastener to stop turning at the correct torque while the drive end twists, advances and then retreats, limiting the torque delivered.
