i'm looking to up rate the bolts that hold the pressure plate to the fly wheel the bolt are m7 x 1.0 but how do you measure the length? do you measure the length of the thread or the length of the thread and head of the bolt?
the length of the thread is 18mm, and the length of the thread with bolt head (the whole bolt) is 22mm
i was looking for some 12.9 m7 x 1.0 but i cant find any does any one where i can sauce some from?
thanks allan
