33mm Torque-Tight™


Product Description


These 33mm Torque-Tight™ Loose lug nut indicators are the mainstay of our product line. The 33mm lug nut is used on most late model class 6,7,and 8 trucks and is by far the most common size indicators sold. Due to many key issues, Torque-Tight™ indicators are a easy way to increase the awareness of the driver during the DOT required walkaround.  

Torque-Tight™ indicators are a small plastic piece that is cut to a teardrop shape, then a 24 point section of teeth are cut to in the shape of a circle that create an interference fit on a standard Hex Nut. Torque-Tight™ indicators are designed to be much larger (more than 2x in fact) than our competitors, this allows for a blatant visual reference when performing a walkaround. Our Torque-Tight™ indicators come in 3 standard colors, Green, Orange, and Black, however they are available in any color you can imagine (with a minimum order).  For less than $25 you can reduce the risk of wheel off accidents, and heck, you may even save a few lives in the process.

  1. Economical safety enhancement

    Posted by Scott Dealaman on 19th Dec 2019

    They are a great aid for driver pre-trip. They are the best way for a driver to determine that the lug nuts are present and tight.

  2. What I needed
