17mm Standard Wheel Nut Indicator - Flat Ring Style (25 Pack)

17mm Fluoro Yellow Wheel Nut Indicators 25 pack loose. Flat ring style designed for 17mm wheel nuts on steel rims.

Our Standard Wheel Nut Indicators are easy to install. They are made using impact copolymer polyethylene to provide stiffness and impact resistance to withstand the harsh and demanding conditions of daily road use. With a melting point of 120℃, these indicators also highlight any overheating issues with the wheel caused by bearing failure or brake drag.

Save time and ensure a thorough inspection process for your vehicle during pre and post-trip inspections. When installed in a uniform pattern, any Wheel Nut Indicator that has shifted position and misaligned with the pattern will clearly identify any nuts that have loosened, are missing or have melted due to a wheel overheating.

Fitment and Measurement Guide

Suitable for many small passenger vehicles with steel rims, including compact cars, small sedans and light imported trailers. Commonly used where smaller wheel assemblies are fitted. 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.
