What is a Wheel Bolt?
A wheel bolt is a type of automotive fastener designed to securely attach a wheel to a vehicle, playing a crucial role in ensuring safety during driving. Due to its importance, it is widely used in vehicle assembly. With precise manufacturing, quality assurance, and reliable performance properties, the wheel bolt is a key component that directly impacts both safety and performance during operation.
To meet growing market demands and safety expectations, automakers require their suppliers to obtain IATF certification and comply with the necessary testing standards and performance requirements for automotive components. During production, high-strength materials are typically used to ensure the bolt’s structural integrity and functionality. Moreover, since automotive components demand a high level of quality control, wheel bolts must undergo strict inspection and sorting processes to minimize defect rates.
Wheel bolts are generally made from high-strength steel, preferably in class 10.9 or 12.9, capable of withstanding high torques and dynamic loads. For increased durability and corrosion resistance, they are commonly treated with zinc plating, Geomet, Dacromet, or zinc-nickel coatings.
