Hi all,

I wanted to try out a plenum divider (Holley 7460). When I put it on along with my heat insulator spacer, my carb studs are not long enough. I have 2 inch studs now and I will need 2 1/4 inch. Looked in jegs and Summit and they do not have them.

1. Where can I find 2 1/4 studs ?
2. What is the problem with just using threaded 5/16 (coarse thread) rod ?
3. Why do they use fine thread on the carb side of the stud anyway ?

thanks

A fasteners supplier can get them.
http://www.mcmaster.com/ might have them.
The fine thread fasteners are stronger since the the root of the thread is shallower and the fine thread has a better holding power in hard materials. In aluminum they use it for vibration resistance.
I forgot why they use a double thread, I think the fine gives a smoother torque.
You could get a longer bolt and cut it. Or thread it further.
A set screw could be used but probably could only be found in this length from a fastener supplier.

WhenI needed longer carb studs, I got them at LOWES. They aren't special parts.

Sear's Hardware also has a good selection of studs for autos. And since the studs do not take a lot of torque you can use almost anything you can find, even cutting the head off a bolt.....
