1/2" Drive x 21mm Deep Length 6-Point Univeral Impact Swivel Socket. Our impact sockets grip the fastener across a broader contact area, reducing chance of rounding off fasteners. They also allow up to 20% more torque to be applied than on other impact sockets. The shift in pressure allows us to reduce the socket wall thickness, increasing access to tight areas.
