Abstract: A wrench socket having a jammed lug nut freeing spring actuated plunger for use with high torque impact wrenches to remove and replace wheel lug nuts from race cars. It consists of a hollow cylinder having an oversized lug nut engaging front end. The interior bore of the hollow cylinder contains longitudinal splines having slots which mate with corresponding projection on splines located on a capped plunger which allows the plunger to move vertically within the hollow cylinder. There is a horizontal removable pin located near the top of the hollow cylinder and extending through to its outer wall. The plunger contains a vertical slot near its top engaging the removable pin. This allows the plunger to extend into the lug nut engaging front end of the hollow cylinder from a retracted position. A compression spring is positioned on back end of the hollow cylinder and the bottom of the plunger's cap.
