I'm looking for longer m12-1.25 bolts for the 4 crank pulley bolts.. need them long to put a crank trigger on. Any Ideas? The factory ones are 12.9 strength.. want to stay the same. Looking for m12-1.25x70 mainly. I've checked everywhere.. cummins dealer..Mcmaster, ace hardware, autozone, pepboys, ebay, Lee auto parts.. I'm desperate. It would seem I have to sttle for 10.9
HELP!!!!

Try these guys. I think they ship. If they have it and don't ship I can pick them up for you and ship what you need.

You can use cap screws if you get stuck. They're usually grade 12.9 or harder.

I think you'd be fine with 10.9's.

Another option would be to buy a threaded rod from McMaster and cut some studs. Also check your local Chrysler, Ford, GM, Toyota, etc dealer's PARTS DEPARTMENT as they usually keep spare bolts on hand.

I think ARP has several bolt sizes in 12.9 rated or higher, it is possible check with them to see what they have. They have gotten into the import tuner scene big time so they now have a lot of metric fastener sizes.

I just searched there site and found the 10.9 only they do not show a 12.9 on the site but try and find a local fastenal and work with them, buy the way the 10.9 costs 3.21 a piece. Hope this helps.

I pulled mine off a 6BT for what its worth. I believe they are hardened also, for what its worth. The bolt size is a common size so it should not be hard to get...

ARP supplied the metric flange head bolts for the C5 Corvette brake conversion on my 1995 Z28.

Be careful with that. The threaded rod (aka studding stick) is usually mild steel, equivalent to a grade 4.6 bolt.
Sometimes known as "cheese".

McMaster-Carr sells it up to grade 8 but not higher, IIRC.

Anyone find these? I need 8 crank bolts for a GM auto setup, my buddy is "borrowing" mine.

My vote would be fastenal. They can order just about anything.
