This set of seven 3/8 inch drive sockets will grip all undamaged and all but the most damaged nut or bolt. This is achieved by the clever use of six cams that move within semi-circular grooves. As pressure is applied in either direction the cams are forced towards the nut or bolt head increasing the grip. Each of the cams are made from high strength alloy steel.
The set includes the following socket sizes: 10mm, 12mm, 13mm, 14mm, 15mm, 17mm and 18mm and are supplied in a folding storage case
