Built for safety, efficiency, and uptime
With all the miles your fleet travels, problems are unavoidable. Rough roads and excessive stop-and-go situations loosen even the most well-secured wheel nuts. Even if a wheel-off situation ends without damage or injury, it still causes downtime and drives your cost-per-kilometre higher. Wheel Nut Indicators NZ are easy to install and provide a clear visual pattern for your drivers. Each pair of indicators points directly at each other, indicating which wheel nuts need tightening and preventing catastrophic or unforeseen events on the road.
