How to Measure Wheel Nuts - Ford is 21mm

Multi-size truck wheel nut indicators quickly identify nuts that have become loose on their studs during transit. These nut indicators are made in Australia and patented worldwide by HexChex.

HexChex is a popular brand of multi-size wheel nut indicators. They are made of a durable engineering polymer and come in three sizes: 19-23mm, 23-30mm, and 30-38mm.

Multi-size wheel nut indicators are a great way to quickly and easily check the tightness of your truck's wheel nuts. They are especially useful for off-road vehicles, as the nuts can loosen more easily on rough terrain.

Indicators are essential in truck and trailer equipment, especially off-road trucking because wheel nuts can loosen on corrugated roads. You should check the truck's wheel nuts every morning for safety reasons.

Importantly, ratchet wheel nut indicators can be successfully installed on most damaged wheel nuts.

Quality UV Materials

Hexchex is made of durable custom-engineered polymer with high dimensional stability, chemical resistance, UV, and thermal properties.

Australia's extreme conditions mean HexChex is exposed to high temperatures.

Wheel nut indicators melt if the hub overheats, alerting you to potential problems.

Other uses for Nut Indicators include:

  • Truck Trailers
  • Vibratory Conveyors.
  • Feeders.
  • Vibratory & Rotary Shakeouts.
  • Screening Solutions for Mining & Aggregate.
  • Grinding and Attrition Machinery.
  • Underground Mining Machinery.

Driving over rough roads can cause nuts to loosen. These multi-size wheel nut indicators are an easy solution to help with maintenance checks.

Did you know that wheel studs are high-tensile steel?

The knurl is essential; otherwise, wheel studs spin during tightening.

Once the wheel stud has commenced spinning, the hole has been oversized. The drum now requires replacement. It is not to insert new wheel studs into old stud holes.

If a replacement is necessary, we recommend a drop of red locktite in emergencies.
