Wheel bolts are commonly found in cars of European brands such as BMW, Volkswagen, Audi, and Mercedes-Benz… Many owners who tend to swap their wheels usually end up replacing the lug bolts to fit the aftermarket wheels. The safety of the wheel bolts is crucial to keep your wheels on your vehicle. A broken bolt can cause your wheels to fall off the hub of the vehicle. Having the wheel fall off the vehicle when driving at high speed is one of the most terrible things that can happen to you. The major reasons for a broken lug bolt that cause a wheel to separate from the hub can be traced back to several things: bolt type, quality, and torque. It may seem like a simple matter to ensure that your lug bolts are properly tightened before driving, but even this simple maintenance act is so often overlooked.

Properly Torqued Your Lug Bolts

Wheel lug bolts are designed to fasten your wheels with a clamping force. When torqued to the manufacturer-specified spec, they will make a strong mechanical connection to the threads on the vehicle hub. It is very important to ensure the lug bolts are torqued to the correct specifications. If a lug bolt is undertorqued, it can continue to loosen itself through the vibrations while driving. As a result, it will unseat the wheel from the hub and create additional vibrations as it spins erratically. This can put pressure on the bolt itself that it was unable to handle, leading to eventual failure, even if the bolts haven’t slid off first and the rim hasn’t separated from the hub completely yet. Over torquing can have similar effects. Stretched lug bolts can lead to warped brakes as loads are distributed unevenly across the hardware. The previously-mentioned cracking and shearing can also separate the bolt from the hub, and potentially lead to catastrophic wheel loss.
