The Dustite combines a loose wheel nut indicator and a protective cap. Ideal for commercial vehicles, the Dustite can indicate movement of the wheel nuts and protect them from a wide range of external elements such as water, dirt, road salts and rust build up. By placing the Dustite in a recognisable pattern on the vehicle wheels such as point to point, any movement of the nut is clearly visible at a glance during visual checks. The Dustite will also melt to indicate any overheating issues. (125C/257F) Dustite 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.
