UNF bolt and stud supplier

[svtmikey]

Hello all,
Does anyone know of a North American supplier of UNF threaded bolts and studs?
I need some slightly longer studs to fit in a lowering block on the rear end of my GT6.
The thread is 3/8 UNF (24 threads per inch).
I can't for the life of me find a supplier here in NA.

Thanks

Mikey

AF has quite a selection of just about everything related to automotive fastening, good luck. Automotive Fasteners

Bolt Depot have a good selection, and you can buy assortments too, which is very handy.
Note that UNF is the same as U.S. Standard fine, or SAE, though these terms are, striclty speaking, obsolete. These threads are available at Sears or other hardware stores, though not always in the grades or sizes you want.

This is only meant as suggestion, Mikey, but I'd try asking around both the local marina and airport who THEY use for threaded fastener suppliers. I bet they're closer than you think.

Uh, Home Depot? Ace Hardware? Practically any place that carries bolts & nuts will have fine thread; though as noted, not always in the lengths and grades you want.

I frequently get mine at McMaster-Carr, because they do stock a wide variety of sizes and grades, and there is a "will-call" counter near my home that is open on Saturday. But they don't usually like to deal in less than box quantities.

Are you fitting a lowering block to a '69 GT6+ with the roto-flex suspension? I've never heard of that before and am curious as to why. That's normally done only on the swing-axle cars with the fixed spring.

I guess my post revealed my lack of knowlege on bolt and thread types.
I was confused and not at all aware that UNF and US standard fine were the same, so when I went to bolt depot and searched I couldn't find anything.....
As for why I am lowering a Roto-flex car, I have shorter springs on the front, so I want it to at least try to level the back up at bit. As it sits now, it looks like my first car as a kid...jacked up.
I wasn't sure how much it was going to change the suspension geometry and handling on a roto flex, but I thought I would give it a try anyway, I can always take it off if it screws things up. Also the spring is new and although it is the correct one, it has introduced a lot more positive camber, certainly more than normal, into the back end (more than I can shim out). Perhaps once it gets some use, it will flaten out.
