Why These Indicators Work

These 20mm standard flat ring wheel nut indicators are a simple, cost‑effective solution for improving wheel safety across light‑vehicles, trailers and hire equipment. Manufactured from robust impact copolymer polyethylene, they are designed to withstand the wear and tear of daily road use while providing a quick, high‑contrast visual reference point for wheel nut movement. The fluoro yellow colour ensures maximum visibility, making it easier for drivers to complete time saving pre‑trip and post‑trip inspections and maintain transport compliance.

With a melting point of 120°C, these indicators also help highlight potential overheating issues, giving drivers an early warning sign before more serious problems develop. Each indicator fits firmly onto the wheel nut in a consistent pattern, offering a convenient and efficient method for routine safety checks.

Designed for steel rims, our indicators are supplied in a pack of 25, making them suitable for individual drivers as well as hire companies looking for affordable, reliable and compliant vehicle safety equipment.
