The Twist Socket from Ken-Tool grips positively into the surface of a ­damaged bolt head or nut to allow it to be removed by using a counterclockwise spiral grip surface integrated into the socket.

The mouth of the socket has six or 12 fluted scallops that cradle the damaged hex head, with the spiral grip surface gently tapering toward the center to pull the socket downward as turning torque is applied.

The Twist Socket can be used with a ratchet wrench, a breaker bar or an air-impact wrench. Twist Sockets are available individually or in convenient sets.
