Wheel nuts losing torque and vibrating off are one of the major causes of dangerous roadway incidents. There are several factors which may play a part in the nuts vibrating off including incorrect initial tension or lack of re-checking, shock loading on studs through clipping objects such as gutters etc, dirt or paint between a set of dual wheels and several other factors.
The Squirrel® wheel safety device is designed to reduce the incidence of wheel loss by applying a direct force against the side of the wheel nut, preventing it from vibrating off should there be any loss of clamping force. As opposed to nut indicator type devices which can only provide an indication of nut movement whilst the vehicle is stationary, the Squirrel® is constantly providing protection while the vehicle is in motion. Quite simply, the Squirrel® is a dynamic safety device – it works when the vehicle works!
