Checkpoint

The original and world’s first loose wheel nut indicator.

Checkpoint® original was invented over 30 years ago. This simple intelligent product is still regarded as the best and highest quality wheel nut indicator available on the market today.

Checkpoint® was the first-ever product of its kind on the global market to provide an indication of wheel nut movement on commercial vehicles. This clever solution helps to ensure that every truck driver and fleet operator can carry out quick and easy visual checks and audits on their vehicle wheels. Its application has since been introduced to a wide range of sectors in order to provide a solution to loosened nuts on plant structures, rail tracks etc.

FUNCTION

The Checkpoint® visually indicates nut movement. By placing the Checkpoints in a recognisable pattern such as point to point, any movement of the nut is clearly visible at a glance. This assists the visual inspection of lug nuts, identifying when a nut loosens, to prevent the wheel from coming off. It also melts at a specific temperature to highlight any overheating issues with the wheel or application.

KEY BENEFITS

An instant visual indicator of nut movement
Indicates possible faults with breaks or bearings through melting
Supports fleet safety checks
Cost effective and easy to implement

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.
