Why do wheel bolts fail?
The wheel bolts are designed to secure the hub combination safely to the car. Most people think that these hard steel parts will not deteriorate or wear, and in most cases they are safe. The most common cause of damage is improper installation of maintenance technicians, excessive torque of lug bolts, or insufficient tightness of lug nuts. However, there are other problems that may cause wear or damage to these parts.
Thread damage on wheel bolts
Improper installation of the lug bolts of the wheel: the lug bolts shall be rotated at least four times manually to ensure that they are properly fixed to the wheel lug. Many quick repair places for replacing tires on the side of the road and owners often forget this before starting to tighten the lug bolts quickly. They should also be tightened in star form and firmly fixed to the hub of the vehicle before they are put back to the ground.
Most unskilled technicians rush or use air impact wrenches that are too high. To avoid cross-thread situations, make sure that the lug bolt is properly installed and then the lug bolt is slowly guided to the wheel until the hub is touched. Wheel bolts touch kerbstones, potholes, or other objects: many steam today have protective “hub covers” or bolt covers that protect wheel bolts from impact.
Rust on the wheel bolts
This usually occurs in areas where cars travel in winter to melt ice in saltwater or sodium chloride on roads. Although many wheel bolts are made of stainless steel and have high rust resistance, it still has the possibility of rust. it is difficult to remove lug bolts or place them correctly on the wheel when wheel bolts are rusty. It is recommended that if you live in areas often exposed to salt, check the wheel bolts once a year for signs of rust. For the purpose of dealing with the performance of bolts under various extreme conditions, the BONOSS products have carried out antirust design and obtained various test certificates to verify their antirust performance.
