Does anyone know the grade of steel to use to make new barrel/crankcase studs for a hybrid engine, I could buy some b50 ones and cut them back and re thread
Or make my own so I need to know what grade to order ? Maybe en9 ?
Cheers

There is nothing wrong with the OE studs; considerably less expensive to purchase a new set, saves a ton of time, however if you are bent on making you own you may want to visit this link:

A bit of history and a view of what ARP is making high stress engine fasteners out of.

The reason I am asking is because I can't buy the length I need off the shelf
Thanks for the info
Cheers
 
I would advise not to cut the threads with a die, thought you might get away with it. you would be better of getting the threads rolled, which involves no cutting like a die cut and is stronger.
High tensile steel rod is available off the shelf of most metal supply merchants – thought some will only supply by the metre.

Yes I see what you are saying, were the threads rolled on the original studs would you know?
 
The parts book that I have only mentions the short studs in the head ( EN9) and the rocker adjusting screws (EN14B) as special materials. No note on the cylinder studs. You need a Rockwell hardness tester...
