I am looking for a 1/2" or 3/4" threaded steel rod (or a bolt at least 4" long) that has been cut so that it has two flat sides. Sorta like this: __ (__)
It allows a nut to be threaded on it normally but the flat sides allow something to be slid over the rod yet not be able to be spun around the rod
-- if that thing has a complementary non-round hole. Does this type rod have a name? Sources? TIA. -- Igor
Only 4" long ? Rod, few nuts, vice and a file.
Well, a hand file will take a time to get the profile igor is looking for, I wager.
Igor, I know what you're looking for, but I don't know a source (nor the actual name, either, not that you mention it)...could (obviously) be made w/ grinder and touch up or start w/ square/rectangular stock and grind to shape then thread. Of course, if you had a mill and lathe, you'd be all set...maybe here's the excuse you've been looking for? :)
Lacking a real source, visit your buddy's shop and while his back is turned swipe the depth bar off drill press! Maybe he won't notice for long enough he'll not know who it actually was. :)
Perhaps not finding a better source you could get a replacement part from a drill press not expensively???
I, too, know what you are looking for. I do not know a name or a source. I have had a few things that had a square cross section threaded on the outside edges. This could be accomplished with square hot rolled stock and a good threading die.

If he's going to file two edges flat and still have the threaded sides workable with a nut, I'd be more inclined to use a die to clean up the threads. Of course, it may depend on the amount of flatness needed and how fine the files is.
Well, yeah, but I think the problem w/ hand filing is that in order to get a profile that has enough clearance he's going to be filing for (TM)... :(
Still think his buddy's drill press depth rod is the most likely candidate... :)
It's only 4" long. That's pretty quick work with most files. Worst case scenario, he uses an grinder and fine tunes it with a really fine file. I'm thinking 30 minutes at best. But, I do like the drill press depth rod idea. It's beyond me why someone would need one of those on a drill press anyway. :)
Starting w/ a 3/4" rod and take off a 1/4" or so on each side is going to be quick w/ a hand file? I don't think so... :)
That's my thinking if can't find (or make) suitably size rectangular stock...
So do I...looked for spare parts and the one I did locate was $75 for a typical Delta... :( Of course, that's the high-priced spread, one might do a little better elsewhere, but as I was afraid, it's not going to be an el cheapo alternative...and, I think that was the whole depth control assembly, not just the threaded rod.
I did do a search for square/rectangular threaded bar stock but had little success (as in none, specifically). Did find a couple of Acme-thread specialists who undoubtedly have/can make such stuff, but no distributors in the short time I looked...
Control depth, maybe??? :) My cheapo Crapsman doesn't have one and I do miss it on occasion...
I do, I did something similar once before when I filed out the inner edge of a 6" diameter hole in one of my 1/4" thick cast iron tablesaw wings to use it as a router table. A rough bastard file took off most of it pretty quick. Of course, I used heavy work gloves to minimize the vibration. It would have been even faster if I had Lee Valley Tools' auxiliary file/rasp handle. Have a look.
Possibly, but I'd have to experience it to convince me. Maybe the metal down in the US is harder than the frost-bitten, brittle cold stuff we have up here in Canada. Especially after the polar bears have gnawed on it awhile. :)
Thread first, flatten after. The flats will make it tough to control a die on the piece.
Any small burrs can be removed with a small file or a brush.

If it were me I'd call up my buddy Bob who owns a machine shop. Since it's you I recommend getting friendly with a machinist. That's how Bob and I met BTW. Have fun. Joe

You need someone with a milling machine and/or a lathe; couple of ways to do what you want. Are you anywhere near Wisconsin, USA?

Well, rectangular. But I'd probably mill a piece of threaded rod and clean it up afterwards with a die, it'd be pretty tough on your die to start with rectangular stock...unless you take it to the lathe first. I could spend all afternoon on this ;)
Unfortunately, nope.
...
Out of curiousity, what are you wanting it for? Perhaps another idea might crop up...
Although, of course, it be made by hand--patience, patience, patience...
I Found one. In my garage on my Drill Press.
The Stop Rod.
It is 6" long, and 1/2" wide and flat on the front and back side.
It is on my 32" Rockwell Radial Drill Press. Perhaps you can contact Delta. It's Rockwell part number is/was
402-01-108-0001
I posted that suggestion some time back...when looking at parts, dear old Delta wanted something like $70 for the particular press I happened to choose... :(
There goes my offer of exchanging shop time for beer (in that order).
