Hi,
what are the measurements for this stud? ePer says M8x25, but 25mm is the length of the threaded part outside the block, how much of the thread is inside cylinder block?

Punto Mk2 (2002) 8v 59HP benz



I contacted Fiat here, 1 stud costs 2€ and copper nut 3€ a piece (Slovenia), so eBay.

Are these correct studs?

Thank you so much. So it's DIN939 :slayer:

BTW, how old are these? On my 2002 all I can see is a pile of rust, I expect a lot of fun and joy removing them.
