Ive dug this old thread (excuse pun) up as im after some info on this m6 bolt.
Does anyone know what the pitch thread is for it ?
As ive got a cam cap bolt that has that feeling of stripping its thread if tightened any further,and its not that tight now

I'm thinking of putting a helicoil in,but want to order the right size before i pull it apart.
Any help appreciated
