Google Patents US6305245B1 - Multiple lug nut removal tool This should be repeated twice, to ensure the wheel is properly centered and restrained by all nuts (as often the first nut that is tightened will be slightly loose after completing the set for the first time), then the wheel should be lowered to the ground and the criss-cross tightening pattern repeated to modest torque (say few fingers force on the lug wrench/wheel brace arm), and then finally repeated to full hand force.US6305245B1 - Multiple lug nut removal tool In this context "finger tight" is tight enough to reach the point where free play is taken up and proper tightening is about to begin, say, the tightening force using the lug wrench/wheel brace like a screwdriver. When re-fitting a wheel, the nuts (or bolts) should be tightened in a criss-cross pattern (to even out the forces) and initially should only be tightened "finger tight" on all nuts. For this reason, impact wrenches should properly be used only for removing lug nuts, not for tightening them, although in practice this rule is often ignored for convenience's sake, even by professional mechanics. Also, uneven torque between the various lug nuts, or excessive torque, can lead to warping of the brake rotor if the car is equipped with disc brakes. Excessive force can strip threads or make the nuts very difficult to remove. Installing a wheel with a lug wrench thus requires a bit of rough guessing about proper tightness. Lug wrenches are much less expensive because they lack the ability to measure or limit the force used. Ideally, the nuts (or bolts) should be tightened with a torque wrench.
