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

Checkpoint® original was invented by Founder and CEO Mike Marczynski over 30 years ago. This simple intelligent product is still regarded as the best 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 vehicles. This clever solution helps to ensure that every driver and fleet operator can carry out quick and easy visual checks and audits. Its application has since been introduced to different 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. 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.
