| For use with 1/2-inch drive impact wrenches rated 380 to 420 foot-pounds of torque; allows use of any impact socket with a torque extension to match the different lug nut sizes found on vehicles.
Extensions help prevent over-torquing of wheel nuts and minimize wheel distortion. The unique design allows the torque shaft length and diameter to flex with each impact wrench blow, once the specified torque is reached. Accurate to within 4 percent. Components are made of chrome vanadium steel and have color coded plastic sleeves.
Set contains the following:
- 1/2-inch drive six-point metric thin wall deep sockets, 17 mm (yellow); 19 mm (red); and 21 mm (orange); and 13/16 inch (blue)
- 1/2-inch drive torque extension bars, 80 foot-pounds/110 Nm (yellow); 90 foot-pounds/120 Nm (red); 100 foot-pounds/135 Nm (blue); and 110 foot-pounds/150 Nm (orange)
