Set includes alloy steel torque sticks and Chrome Molybdenum impact sockets, which are hardened, tempered and anodised for corrosion resistance. Both are designed for use with air and electric impact wrenches and are colour coded for ease of selection. The torque sticks prevent over-torquing of wheel nuts which causes distortion of wheels, drums and discs which can produce brake pulsation. Torque sticks can be used with any impact grade sockets and are especially suitable for thin-walled sockets. Popular torque rates for most cars and light commercial vehicles. The impact sockets are sleeved to prevent damage to alloy wheels. Supplied in carry-case.
