Topic tags/keywords: press wood nut question

Hi, guys -

It’s been awhile…hope everyone’s doing well.

I’m building a small press for gunsmithing purposes. I’m going to use 5/8” steel rod as the bolt, and I need to a nut that I can make captive to the frame of the press. Not knowing what such a nut is called (if it even exists) makes googling difficult. I suppose I can just make one from a scrap of steel, by threading it in the middle and drilling fastening holes in the corners, but I thought I’d ask if anyone here knew of a source for something like this.

Thanks.

I assume you are looking for a threaded insert.

You might have some difficulty finding one that large, though.

Yeah, that’s the idea, but (as you suggested) they don’t seem to come any bigger than 3/8”. I also don’t need the fastener to be embedded in the press; a surface mount of the nut is OK.

Any other ideas? Otherwise, I’ll just make a couple.

Yeah, a threaded insert might work, or a T-Nut (teenut) – you should be able to find either at a hardware store in the little bins. Or maybe a heli-coil might work – you can find them at an auto parts store.

Threaded inserts will be hard to find in that size. I would think just drilling and tapping a hole in a piece of steel would be the way to go. Or something like this?

Hmm…that press screw is an interesting idea. I wonder if the square foot screws off.

Thanks for the suggestions, guys.

It also occurred to me that a galvanized wall flange would suit your needs perfectly if pipe threads were okay.

Pipe threads generally taper so they can form a tight joint. There are Electrical connectors that don’t use tapered threads. Rigid conduit connectors aren’t tapered I don’t think. Or you could get a small cast flange and try tapping it to the size straight thread you want.

Try looking for a T-nut. They’ll go up to 5/8” and larger, although large ones are a little more difficult to find.

Thanks for the ideas, guys. You collectively confirmed to me that there wasn’t really any easily obtained off-the-shelf answer for this, so I just made myself a couple, from 3/8” steel bar stock.

Now, I have to figure out how to attach a handle to the threaded rod I’m using, but, as that’s a metal-joining issue…that’s a question for a different forum.

Thanks again.
