Of Wheel Nut Loss

Wheels come off when the wheel nuts holding the wheel to the vehicle lose clamp force and become loose. There can be a number of reasons why a wheel nut can become loose.

Often users will over-torque a wheel nut with the reasoning that tighter is better. However, over-torquing actually stretches the studs or threads beyond their ability to respond. It can also result in cracked, seized or cross-threaded nuts and cracked wheels. Conversely, under-torquing results in the nut unthreading when subject to vibration.

Excessive braking or worn bearings can result in high temperatures, causing the wheel bolts to expand and contract as the temperatures vary. This causes the wheel nut to lose its grip on the bolt, resulting in a loss of torque.

Improper mating surfaces can be caused by contaminants such as dirt, rust and paint and also by old nuts and bolts, damaged or bent hubs and wheels, and worn or elongated bolt holes. These uneven surfaces can create “false torques” between the nut, bolt and wheel surfaces, where the force is used to overcome friction and is not converted to clamping pressure.

The Safetytrim System

  • INDICATES - a yellow tab appears in window if a nut has lost clamp force and de-torqued

  • LOCKS - it prevents that nut from turning any further than 1/6th of a turn

  • SAVES TIME – in daily walk around and vehicle checks and audits

  • PROTECTS – the nut from weathering, corrosion and general road damage

  • DURABLE - made from automotive engineering grade material able to withstand extremes of temperature and conditions

  • USER FRIENDLY - can be fitted and removed in seconds using the supplied removal tool

  • COMPANY IMAGE - clearly shows best practice and looks fantastic
