Features and BenefitsAn instant visual indicator of wheel nut movementIndicates possible faults with breaks or bearings through meltingMelts at a specific temperature of 125C/257FSupports fleet safety checksCost effective and easy to implementThe world’s first biodegradable wheel nut indicators*The Checkpoint visually indicates wheel nut movement. By placing the Checkpoints in a recognizable pattern such as point to point, any movement of the wheel nut is clearly visible at a glance. This assists the visual inspection of lug wheel nuts, identifying when a wheel nut loosens, to prevent the wheel from coming off. It also melts at a specific temperature (125C/257F) to highlight any overheating issues with the wheel or application.Checkpoint provides a clear commitment to health and safety, and roadworthiness to other road users, and road and transportation associations such as: DfT, FORS, DVSA, HSE, FTA and RHA.*Tested and verified by ASTM D5511 for enhanced biodegradation in biologically active landfills, saving the planet from over 200 tonnes of plastic waste each year.SpecificationsMaterialsHigh-grade virgin polymer to ensure product quality and performance reliability for overheating indication.SPEC SHEET
