14mm differential bolt upgrade

[DSTX17]

I am doing the 14mm differential bolt upgrade with a akg 14mm front diff bushing. I would like to have a bolt in there that has a shoulder, I think thats what it is referred to anyway ( no threads in the bushing section). Does anyone know where I can purchase this bolt?

The dealer. Gonna be about $15-20.

I got mine at bimmerworld IIRC.

McMaster-Carr since you know the exact specs of what you need.

Maybe some snazzy washers and a flange nut to along with it!

That's a through hole, so get a bolt that will protrude about 1/2". That way, if it ever breaks, it's so easy to remove the stud.

If you do decide to get some rando bolt from a store instead of the proper bolt from the dealer, make sure it’s a grade 12.9, NOT a 10.9 and most certainly not an 8.8.
