Features and BenefitsA dual-purpose wheel nut indicator and retainer.A visual indicator of wheel nut movementHelps prevent loosening of wheel nutsIndicates possible faults with breaks or bearings through meltingMelts at a specific temperature of 125C/257FSupports fleet safety checksThe world’s first biodegradable wheel nut indicators*Placing a Checklink across two adjacent wheel nuts helps to prevent the loosening of wheel nuts. This clever product both indicates and retains against unwanted wheel nut movement as well as indicating any overheating of wheels caused by faulty brakes or bearings. Connecting two adjacent wheel nuts with our specialist polymer in our distinctive S shape provides a retaining function, causing resistance to the loosening of wheel nuts. If the wheel nut still manages to loosen, this will be indicated by the distortion of S shape.The Checklink wheel nut indicator provides a clear commitment to health and safety, and roadworthiness to other road users, commercial vehicles, and road and transportation associations such as: DfT, FORS, DVSA, HSE, FTA and RHA.*Checkpoint products contain a Bio Additive that has been validated by independent ASTM D5511 tests to yield enhanced biodegradation in Landfill Conditions, saving the planet from over 200 tonnes of plastic waste each year. 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.SpecificationsMaterialsHigh-grade virgin polymer to ensure product quality and performance reliability for overheating indication.DocumentsSPEC SHEET
