Ball seat wheel bolt, also described as radius seat, in M12x1.25, M12x1.5, M14x1.5, 1/2-20 and 9/16.

A wheel bolt threads directly into the hub, so it is the fastener used on bolt-located wheels rather than on stud-located ones.
This item is the ball seat version, also called a radius seat. The seat shape has to match the wheel, so a ball seat wheel takes a ball seat bolt.
Distributors, wheel retailers and workshops fitting cars, off-road vehicles, 4x4s, trucks and SUVs.
