Checkpoint CTR32 Checktorque Red wheel nut indicator - Red 1 1/4 in (32 mm) (Bag of 100 pcs)

The Checkpoint visually indicates wheel nut movement. By placing the Checkpoints in a recognisable 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 (125ºC/257ºF) 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.
