60° Conical Seat for Fitment

The 60° taper seat is the standard geometry for most aftermarket alloy wheels and a wide range of OEM fitments. As the bolt is tightened, the angled face centres the wheel concentrically on the hub and creates a secure mechanical lock. 

This seat type must match the wheel; fitting a conical bolt to a radius-seat wheel prevents full surface engagement and compromises wheel retention.
