Reply to "Front brake rotors?? Has anyone found a set?"

Hi the issue is not the actual size of the threaded portion of the stud. You are correct 12mm is smaller than the 1/2 inch equivalent (12.7mm). I did find 12mm studs that would not lock in the stock hole of the rotor. The issue that requires sizing is the matching of the spline below the threads that prevents the rotation during tightening the wheel. I’m happy to hear that you found a stud that matched with sufficient interference to change from inch to metric. I was not that lucky and had to ream the holes to change from 1/2 inch to 12mm and achieve the correct interference.
