Common questions
How do I know my wheels take ball seat bolts?
Look at the contact face of a bolt you are removing. A rounded, dome-shaped face is a ball seat, which is common on factory Mercedes Benz, Volkswagen, Audi, and Volvo wheels. A straight tapered face is a conical seat, and the two are not interchangeable.
What should I measure before ordering?
Match three numbers from your existing bolt: the 12mm x 1.50 thread, the 27mm shank, and the 54mm overall length. Our application guide page can help confirm your specific vehicle, and these are priced per piece so you can order the exact count you need.
