Why These 34mm Indicators Work

These 34mm standard flat ring wheel nut indicators offer a reliable, cost-effective way to improve wheel safety across heavy vehicles and specialized transport equipment. Manufactured from durable polyethylene, they are built to handle the constant vibration and grit of daily road use. The Fluoro Yellow colour provides a high-contrast visual reference, allowing drivers to streamline pre-trip and post-trip inspections while ensuring consistent transport compliance.

Finding the Right Fit

While many modern trucks use 33mm wheel nut indicators, this 34mm size may be a more suitable fit for specific Scania, DAF, and MAN configurations or heavy-duty trailers with 34mm A/F (Across the Flats) hex nuts on steel rims.

With a melting point of 120°C (120 degrees Celsius), these indicators do more than track movement; they act as a vital warning system for overheating brakes or bearings. This allows drivers to identify mechanical issues before they escalate into a roadside failure. Supplied in a pack of 25, these are a durable, affordable solution for operators prioritising safety and efficiency. Buy online to take advantage of bulk discount pricing and free shipping.

Compatibility, Fitment and Measurement Guide

While 33mm is common across many modern fleets, this 34mm indicator is a more suitable fit for specific heavy-duty and European-spec configurations found in Australia.

• European Equipment: Ideal for specific Scania, DAF, and MAN models where a 34mm hex is required.
• Specialised Trailers: Frequently used on heavy-duty low-loaders and livestock trailers with non-standard wheel ends.
• Steel Rim Focus: Designed for flat-seated hex nuts on steel rims (not for recessed alloy nuts).

Suitable for some European trucks, heavy buses and specialised heavy‑duty trailers fitted with steel rims. Often used in mixed fleets running European‑spec equipment. Always check your wheel‑nut hex size before ordering.

How To Measure

Measure across the flats (A/F) with a vernier caliper, or check the socket size that fits your wheel nut — both methods give you the correct hex size.
