It Is A Little Puzzling How Many Set Screws Are Needed In The Wheel Hub Assembly It Is A Little Puzzling How Many Set Screws Are Needed In The Wheel Hub Assembly

For set screws of automobile wheel hub assembly, it is believed that many people do not count them themselves because some cars have four, some cars have five. So the question is, what's the difference between four screws and five screws? Can it be unsafe if a screw is missing?

First of all, these screws is used to fix the wheel hub assembly. Then, can it be unsafe if a screw is missing? It is not. Before the cars leave the factory, they are rigorously tested such as bench test, road test, etc. So whether it is 4 or 5, there is no difference in essence, because a screw will not affect the safety of driving. In Formula one racing, secure with a screw for convenience of replacing the tires.

Of course, do not worry about the quality problem of screws. As is known, the tire relies on the wheel hub assembly, and then the powerful power system ultimately outputs all the power from the axle to the wheel hub assembly. And hub bolts(set screw mentioned just now) are the means of transmission. It can be said that the design and calibration are very careful, so do not worry about the quality of parts. As for the number of screws, it is not arbitrary. It is related to the vehicle weight, wheel hub assembly stress and weight distribution. In general, the family car of about $100,000, there are 4 set screws in the wheel hub assembly. However, for medium - and large-sized vehicles such as SUV, five screws are basically required to fix them. For some luxury models, six screws are also required.

All in all, the number of screws in the wheel hub assembly depends on whether your car is SUV or luxury car or family car. Of course, the number of screws are calculated by the engineers according to the weight of the car body and the bearing capacity. It is not more or less, so don't worry.
