I've got a project that is calling for internally and externally
threaded stainless tubing. I'm having a hard time finding what I need,
so I thought I'd ask here before I draw up a plan and get a quote from a
local machine shop.

What I need is something like this:

| \\ | | // |
| // | | \\ |
| \\ | | // |
| // | | \\ |

With the inner hole on the externally threaded tubing being .055-.070
and the thread size being 8-32 (one size up or down would be fine, but
10-32 is pushing it) and the OD of the internally threaded tubing being
about 1/4". I need them about 1/2" long, though longer is fine, as I
can cut them down to size.

I'm looking for about 300-500 of each.

Thanks for any help!

Also, I'm looking for either split brass tubing, or bead rolled brass
strip. It need to go on/around 22ga stainless. Say between 1/8"-1/4"
OD.

The final effect is something like this:

(Not my work, just found something of similar style)

Thansk again!

Find the appropriate sized tubing and thread it yourself?

How deep do you need the threads on the inside-threaded part?

Threading some varieties of stainless is a real treat, if you like
cussing and broken taps. I'd check McMaster and other sources out there
for what alloys are available, then I'd check back here for what may be
machinable.

If your outer-threaded parts are short enough you may be able to drill
out screws.
