I have a pair of brand new pivot bolts. The pivot shank is exactly 11mm which I guess is to give a bit of clearance in the 7/16" hole in the frame. There is a taper on the shank where it meets the 5/16" x 26 tpi thread which will help pull the bolt tight to the inside fork of the stand. Finally there is a slim locknut. Ron
