The use of the right professional tool prevents the over-tightening of wheel lug nuts and stud breakage or alloy wheel damage, advises Jie Yang when using any 1/2" impact wrench. This set includes a wide range of torque settings (90 - 200 Nm). The torque setting is to help apply torque to the correct tolerances. Colour-coded and engraved with torque range for quick reference. http://jieyang.imb2b.com/
