In many cases, it is easy to confuse the two concepts, or there is no clear distinction. In our view, Wheel Bolts are generally used to directly fix the wheel to the hub axle, which can be directly removed by HEX17 or HEX19 sleeve + wrench in most cases. Most European car models such as Mercedes-Benz, BMW, Audi, Porsche, Volkswagen, Citroen, and Volvo commonly use this structure. While the Wheel Studs are morecommon in Japanese and American car models, such as Toyota, Honda, Nissan, Mazda, Buick, Chevrolet, etc., Wheel Studs have been fixed on the hub axle so that the disassembly and replacement is relatively complicated, and it is necessary to use Wheel Nuts to fasten the wheel after place it onto the studs.
