What is it?......... with a twist.

And the twist is........ it's a machined thread. But it's part of what?

This one is going to be harder... lets see. A bolt would be too obvious, and the threads are squared. Looks like a bit of rust on the left middle. The top half down to where the rust starts most likely goes in and out of what ever it is attached to which is why it looks cleaner.

If I had to guess its part of some sort of shop tool like a bench drill.

it's a jack-screw but there's no way to tell from what. Not possible. Only it's function to move an object with precision.

You're on the right track!

........The top half down to where the rust starts .......

Not rust..... it's ambient light.

Good Grief!!
Maybe you folks that *know* about machined threads can look at one and say what it goes to, but to me, this is like posting a photo of a button and asking what article of clothing it would be sewn onto!

Drill press?

Bench vise?

Bench vise?

The vise part is correct........

 

[davesnothere11]

Ok then a pair of vise grip pliers?

 

[Josh66]

So, a vise, but not a bench vise?

A drill press vise? (Machining vise)

OK, a slightly wider view:

Woodworking vise?

I know what it is, but i can't remember the word in English..
