Another what are they thread?

These were part of an auction lot. Not sure what they are or in some cases what type of machine they go to? Would love help id'ing to decide if I should try to resell them or put in scrap/project material bin. I have a couple of the round things with the rohm stamp on them-some sort of chuck part? The giant machinist jack looking thing, doesn't actually screw up or down, but does slide. The long skinny thing looks like a tapered gib. The big brake rotor looking thing has a Fastenal number on it, but searching at their site doesn't bring anything up. The part with bent tubing and the setscrews I was told was a tool holder for some sort of cnc tool, but no other specifics were known. The part wrapped in newspaper is the same as the one above it and says "spindle flange shaft" on it, but no indication of what type of machine.

They look like fixture details for production machining operation. They were probably ordered with the original tooling for backup details for a long or high volume production job!

First photo, that thing in the center, whenever I order pizzas they come with them.

That's exactly what I thought when I picked it up!

The 4th pic the one part is a tool holder for a CNC lathe turret.

Wish I could help you on the rest of the stuff.
