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.

Why Fleets Choose Torque-Tight

  • Made in the USA with consistent molding quality
  • Injection-molded for precise fit and long life
  • Color is molded through the part, never painted
  • UV-stable polyethylene resists fading and cracking
  • 1/8 inch thick for durability and secure fit
  • Two-year warranty

How Drivers & Technicians Use Them

  1. Install all indicators pointing the same direction.
  2. During pre-trip, look for any indicator rotated outward.
  3. Any rotation indicates a lug nut requiring immediate service.

Temperature & Environment Performance

Torque-Tight indicators are molded from a high-performance LDPE resin designed for long-term outdoor use. The material remains stable across brake heat cycles, winter cold, UV exposure, and chemical contact.

  • Operating environment: −40°F to over 250°F
  • Short-duration heat tolerance well above typical brake drum temperatures
  • UV-stable colorant prevents fading
  • Resistant to oils, grease, salt, and de-icer chemicals

Why We Don’t Use Biodegradable Plastics

Some indicator brands use biodegradable or oxo-degradable plastics. These materials are not recommended for heavy truck environments because they can lose strength when exposed to sunlight, heat, vibration, and road chemicals.

A wheel-end safety device should not degrade outdoors. Torque-Tight indicators use an engineering-grade LDPE chosen for durability, long service life, and consistent performance.
