Making 6-32 threaded Rod
I'm planning on making some 6/32 threaded rod for a project. Where can I source some .138 rod to fabricate
with a 6/32 die?

Why don't you just buy it, its only a couple dollars for 6 feet.

Re: Making 6/32 threaded Rod
I have to cut each piece to be 5" and then thread both ends. Then bend it into a square u-shape. Haven't been
able to find it on the internet. I would purchase it if I could find it.

Try looking for 3.5mm rod or wire.

I think it's out there but I can't remember where I saw it. If you can't find it, could you go with 5/40? That's a 1/8 rod. Also if you don't need steel, you can get brazing rod in 5/32 and take the ends down a few thou to thread #6.

Use #36 01 drill rod from Victornet.com. $2.36 per length.

Re: Making 6/32 threaded Rod
Can this material be easily bent to the enclosed shape? I need to make this out of a metal that's easy to bend.

Hi Bob,
#6-32 is not the best choice to use. #5-40 would be much better (which is also the right size for 1/8" dia.).
The reason is that the ratio between the thread OD and the root diameter is highest for #6-32 and so it is the hardest thread to cut and also the most difficult to tap, especially in a blind hole. The taps break easier and the cutting torque is highest both for dies and for taps.
I used to use #6-32 because I thought it was right for 1/8" dia. but now I avoid it whenever possible.
Yes, you should be able to bend it OK, but you will likely have to thread it first because you won't be able to get the die in position afterwards. It depends on how sharp a bend you need and what the material is that you are using. You might have to heat the bends either before you start or even part way through the bending process to avoid having the material break at the bend due to work hardening. Try at least one bend on a scrap piece first, just to be sure.

Re: Making 6/32 threaded Rod
Richard: I would have no hesitation to use a #5-40 die. I was planning on cutting the threads before bending as you suggested. If you viewed my drawing the bends are 90 degrees in a square U-bolt shape. I would want to use
some soft type of steel or possibly aluminum stock. I have to make about 50 of these for a scale R/C model I'm designing. There not stress on the part so strength is not an issue.

Re: Making 6/32 threaded Rod
Well, I was going from memory. You need #29 drill rod not #36. Victor Machinery has that too as does McMaster and others. Years ago I did what you want to do but with 4-40 and I bought drill rod to do it. It should work fine but you probably should make a punch and die to do it in a press. Nice thing about drill rod is that you can heat treat it afterwards if that is a consideration for your project.
