Mazb, I located my 2 1/2" 8-32 socket head cap bolts from a nut a bolt distributor here in Tampa. They had everything from huge truck bolts down to the size I needed. Home Depot, Lowes and even Ace Hardware could not help but Ace sent me to the distributor here in Tampa.

I see you are from Houston which is a bigger city than Tampa. Try the Yellow pages. I'm sure some nut and bolt company in Houston will have what you need. Good hunting.
