Reply to "Bolt size"

DannyP

I have a tap and die set that has 12mm x 1.5mm and 1.75mm, so hence the fine and coarse thread definitions. I prefer to just write the actual size to totally eliminate any confusion. VW/Porsche indeed use both 12mm and 14mm, both in 1.5mm pitch.

I'd buy the bolts only and have a local machine shop chamfer your adapters.
