A 10-inch, 1-inch drive torque stick that flexes at 475 ft-lb to protect wheels and studs from over-tightening
The Steelman 60164 is a 1-inch drive torque extension built for commercial tyre shops and heavy-duty fleet maintenance. It limits impact-wrench output to 475 ft-lb so mechanics can tighten lug nuts without shearing studs or warping rotors. The 10-inch length keeps the hammer mechanism clear of alloy wheels. Yellow powder-coat makes it instantly visible in a crowded tool drawer.
Under repeated daily cycles the Chromoly steel body absorbs peak spikes by flexing rather than transmitting excess force to the fastener. This elastic behaviour remains consistent across hundreds of operations, protecting wheels and brake components shift after shift. The 6-point drive engagement distributes load evenly, reducing rounding risk on worn or corroded nuts.
As a passive steel bar the tool generates no heat, draws no power and produces no noise of its own. Only the driving impact wrench contributes sound and vibration. The powder-coated finish resists corrosion from brake dust and road salt, so the extension stays serviceable without lubrication or special storage.

The chrome molybdenum steel extension absorbs excess impact by flexing at 475 ft-lb, so it does not produce measurable heat under normal operation.
A 1-inch drive electric or pneumatic impact wrench is needed to fit the extension and allow it to limit torque to 475 ft-lb.
Yes, the 10-inch chromoly steel bar fits standard 1-inch drive sockets and protects existing wheel studs and rotors by flexing at the rated torque limit.
