Kerékcsavarok

Kerékcsavarok, also known as wheel bolts, are crucial fasteners used to attach a vehicle's wheel to its hub. They are typically made of hardened steel and feature a threaded shaft that screws into a corresponding threaded hole in the wheel hub. The other end of the kerékcsavar has a head designed to mate with a seat in the wheel. This seat can be tapered (cone-shaped), ball-shaped, or flat with a washer, depending on the wheel design.

The primary function of kerékcsavarok is to securely hold the wheel in place during driving, preventing it from detaching. When tightened, they create clamping force that presses the wheel against the hub assembly. The correct torque specification for tightening kerékcsavarok is essential for safety and to prevent damage to the wheel or hub. Overtightening can strip threads or crack the wheel, while undertightening can lead to the wheel becoming loose and potentially causing an accident.

Kerékcsavarok come in various lengths, thread pitches, and head designs to accommodate different vehicle makes and models, as well as different wheel types (e.g., alloy vs. steel wheels). It is important to use the correct type and size of kerékcsavar for a specific vehicle. Replacing damaged or worn kerékcsavarok is also a critical maintenance task. They are typically removed using a lug wrench or a torque wrench.
