Found this vise laying around, seems to be missing the nut? ACME thread I'd assume. Or are there more bits than that missing? Doesn't even have a name or anything on it so might not be worth the hassle to find the parts.

>Or are there more bits than that missingYou'd also need a washer big enough to hold the threaded part in the stationary half to close the jaw

ACME / Trapezoidal is terrible for clamping, that's a square thread. I'd say it's not worth the hassle..

That's about 35% of a bench vise. Yeah, you are missing most of it.

As the other anon said it's a square thread. You're probably not going to find a nut to work with your current thread. You can buy acme threaded rod and a coupling nut or a couple of standard nuts and make your own if you're willing to put in the work. I've heard the naysayers say that acme threads aren't as good in vises, but I repaired one exactly how I mentioned and it's been wailed on relentlessly for years now.Get some better pictures of the fixed jaw inside where the slide goes with better lighting. Most of them have a dovetail like feature where the vise nut slides in and is retained by the tapered walls and maybe a bolt as well.Pic rel is the first time I broke and fixed my piece of shit abused vise. 2nd time the nut stripped out so it got replaced with acme thread and a home built vise nut. 3rd time I cracked the stationary jaw casting and welded er up with some nickel rod... It's still getting abused pretty much daily.
