Where can I find threaded brass rod for equip rack

I built a rack for my system a few years ago using MDF and threaded steel rods. I would like to try to replace the steel with threaded brass rod, washers, and nuts. Any idea where I might find such a thing???
I got some nuts for ya
For starters, you might try http://www.nolansupply.com/.
Would those teeny, tiny, troll nuts?
Ok i will bite.
What is this troll thing? I've been seeing alot of references to trolls latley.

Hey Nrchy, did you check home depot?
They might have stuff like that in thier lamp section. They might be hollow though
Slappy, I need solid brass, not hollow, and I'd prefer 3/4" which makes it even more difficult.
Try McMasters or Graingers. Both should have it.
McMaster Carr has threaded brass rods at 69-72" lengths 5/8 inch right or left hand thread. They are $58.19 each. 5/8" right or left hand thread brass hex nuts at about $4.00 and change each. For a two shelf rack, you are looking at about 320.00 for the rods, washers, and nuts in brass. I've been building different style DIY racks myself (currently have 3 configurations complete), and a two shelf model with large solid rock maple slab shelves and 5/8" brass hardware prices out at around 440.00 for materials.
Yep McMaster-Carr has threaded brass rods. My catalog #106 (page 2791)
list lengths of 2,3,&6 ft. in both coarse and fine threads.
There is also ACME threads (more square 29° vs. the common V
type 60°) but they are in different materails.
Hope this helps.
Wow, I'll check this out! You guys are great!
