1-1/8” Torque-Tight™ loose lug nut indicator fit some trucks that are in classification 3, 4 and 5. Measuring a lug nut at this size to get a correct fit is very important because sizes move up or down by 1/16”. To make sure you are ordering the correct size please reference our How to Measure portion of our web site. Our 1-1/8” Torque-Tight™ loose lug nut indicators are designed to fit on both 1-1/8” and 28mm nut. 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.
