The Caravan and Truck Wheel Nut Indicator Helps Prevent Loose Nuts
Hexchex 23mm-30mm multi-size truck wheel nut indicators quickly identify loose nuts on their studs during transit. They are made in Australia and patented worldwide by HexChex.
HexChex is a famous brand of multi-size wheel nut indicators. HexChex indicators are made of a durable engineering polymer and come in three sizes: 19-23mm, 23-30mm, and 30-38mm.
Why Wheel Nut Indicators Simplify Maintenance Checks
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 handy for off-road vehicles, including trucks, as the nuts can loosen more easily on rough terrain or corrugated roads.
You should check your truck’s wheel nuts every morning for this reason.
Importantly, ratchet wheel nut indicators can be successfully installed on most damaged wheel nuts.
Hexchex is made of a durable, custom-engineered polymer with high dimensional stability, chemical resistance, UV resistance, and thermal properties.
Australia’s extreme conditions expose HexChex to high temperatures.
Wheel nut indicators melt if the hub overheats, alerting you to potential problems.
Other Applications for Nut Indicators
- Truck Trailers
- Vibratory Conveyors
- Feeders
- Vibratory & Rotary Shakeouts
- Screening Solutions for Mining & Aggregate
- Grinding and Attrition Machinery
- Underground Mining Machinery

Did you know that wheel studs are made of high-tensile steel?
The knurl is essential; otherwise, wheel studs spin during tightening.
Once the wheel stud begins to spin, the hole becomes oversized. The drum now requires replacement. Do not insert new wheel studs into old stud holes.
If a replacement is necessary, we recommend a drop of red Locktite in emergencies.
