Exhaust bolts: my Gogglefu is weak

My Googlefu is weak

I’m looking for M10x45 and M8x30 bolts with a Etorx head, 12 point or small head head to get in tight quarters. And I want them by Thursday. For cheap.

I was at Home Depot today and found a pack of M8 x 30 flanged bolts, but they only had one. The Home Depot guy and I couldn’t even find a bin for it, it’s almost like it was a fluke they were there.

FCP and ESC have them, but at ridiculous pricing.

McMaster-Carr doesn’t have them or I couldn’t find them.

Edit: small head head nuts to go with them is a plus. Copper maybe?

Thanks!

Have you checked at an auto parts store? I know Advanced Auto has a wide range of bolts. Getting the quantity you need can be frustrating as is finding the size since they’re typically all out of place.

Fastenal?

Looks like there are a lot of stores near you.

ARP has exhaust bolts. You'll pay for them though. They sell quality stuff.

Excellent choice but I can’t get them by Thursday for a reasonable price.

I need them Thursday, because I need to install them on the BMW Friday morning before I leave for the track.
