41mm Standard Wheel Nut Indicator - (25 Pack)

41mm Standard Wheel Nut Indicators provide a quick, visible solution to detect wheel nut movement, reducing the risk of wheel detachment. Made from durable, highly visible, fluoro yellow Polyethylene, they fit firmly onto wheel nuts and only shift if a wheel nut loosens, signalling the need for maintenance. They are specially designed for 41mm wheel nuts on heavy-duty steel rims.

In addition, these point-to-point indicators melt at a specific temperature of 120°C (120 degrees Celsius) to highlight any overheating issues with the wheel. Ideal for trucks, buses, and trailers, these indicators are perfect for improving vehicle safety and maintenance efficiency, keeping you on the road.

Applications: Ideal for trucks, buses, and heavy-duty commercial trailers. These are a vital part of daily fleet pre-start safety checks and preventative maintenance.

Fitment and Measurement Guide

Commonly used on ultra-heavy mining equipment, industrial plant machinery and specialised heavy-haulage trailers with steel rims. Designed for harsh operating environments that require enhanced durability and visibility. 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.
