'97 Z3 1.9l valve cover bolts

[JSVice]

Is there any way to get the specs on these bolts? When removing one of the valve cover bolts, the threads came with it. I now need to do a helicoil insert in the hole, but I don't know what size. I searched the forums and Google, but can't seem to find what I need.

M43 or m44 engine?

M43 or m44 engine?

It's a '97 1.9, so I believe that makes it an m44

Just had a look on real oem it only lists the bolts as
( longer ones) 6mm × 42.5
( shorter ones ) 6mm 27.

So 6mm. Thank you so much.
