1/2 in.; Drive x 21mm Extra-Thin Wall Wheel/Nut Protector 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.
