31mm Torque-Tight loose lug nut indicator have been used for indicating loose lug nuts in truck classifications 5, 6, and 7 but is not a common size used. Measuring a lug nut at this size to get a correct fit is very important because sizes move up or down by 1mm. To make sure you are ordering the correct size please reference our How to Measure portion of our web site. 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.
