Alignment pins

Probably not a tool. Looks a bit like a cushion for a hydraulic cylinder.

no neat sig line

Doesn't look like anything I would need in a machine shop. Might be something the machinist did a nice job on and they were "trophies". Most machinists have odd pieces in the tool box over the years for a variety of reasons.

Might have been spares on a repeat job. Having a couple of spares in your tool box that helped production get back up and running is a good thing.

Also, I would often make 12 of something when I only had to make 10 in case I f*cked up one or two. The extras, even though now scrap, would be used for set-up of further operations. Can't ruin something further that's already ruined but can test whether the set-up will produce good parts for the remaining batch.

Steve's guess makes me think of yes, alignment pins of a vehicle having body-on-frame construction, when mating the two, at points of attachment. Set the rubber with steel sleeve biscuit in-place. Insert the alignment pin. lower the body onto the pin. Remove pin, insert fastener.

Don't body shops use those for measuring distances between points on a frame, where holes are made, for 'pulling' frames?

I too vote for Alignment Pin

Those are clearly robot **** plugs.

An alignment pin would not need those holes around the base, they look like they are for lubrication.

any idea on what the machinest did or worked on?
