The Blue Tork nut runner is a precise tool used to torque lug nuts on truck wheels to very specific ft. lbs. It is light weight, quiet, and extremely accurate. There is no physical or manual labor to perform. The tool does all the work. It is used by many National companies, large trucking fleets, State DOT's, city municipalities, and trash haulers. The tool will soon be available in a cordless variety with the same power and features as the pneumatic version. We also offer a free training program for your shop and techs on the 'Wheel Torque Solution' process for maintaining wheel ends.
