Supercharger to head bolt snapped, where to urgently get a replacement?

Dear all, when fitting the ported blower, I snapped one of the supercharger to head bolts. I urgently need a replacement, as I got a date for a tune I cannot move. Where can I order a replacement bolt that would ship within 1 or 2 days? cheers cirpower

Why not go to True Value and get a bolt there?

Dealer. These bolts are single use and must be replaced. Sorry you didn’t see this in your other post asking for the torque and patten

There are 10 total...with the sealing o-rings, I think you could get by without one of the fasteners...(temporarily!)

Torque is only like 89 inch/pounds...

If they are like the Magnuson's they are M6 bolts and mine torque at 108 inch pounds, GM might be less. When I worked for Magnuson a guy was bolting his down and snapping off all the bolts, he got confused about inch pounds and pounds. I got him straightened out and we sent him some new bolts.

I could be wrong, but I find it hard to believe that those tiny ass little bolts are tty.

If you need a single bolt run to the dealer. They will sell you a single bolt. If you order online they will probably only sell them as sets.


Also, I hope you can get the bolt out of the head....I believe the torque specs is 44in/lb first pass then 88in/lb second pass.

Thanks everyone for the great help. I did re-use the OEM bolts, but for next time I would buy a set of new bolts for sure.

I broke one bolt (be careful, they break easily). Fortunately, they break further up and not in the thread, so I could easily remove it from the head.

Home Depot sells an M6x95mm bolt (pitch 1.0) and that one worked just fine to replace the one I broke.

I would definitely recommend to everyone doing this work to only use a small ratchet and be very very careful.

cheers
