Found this in a Old Bolt Bin that I bought - What are they?

[HKlassen]

I bought an old bolt bin from a farmer who was retiring. I found about 50 of these in one of the bins but have no idea what they are? Can anyone shed some light here? I included the quarter to give a sense of scale

I'm gonna guess some sort of die for pressing snaps or something similar, although there should be another part that these mate with. Maybe even just to dimple metal?

OP said there were fifty of these. That is a lot of the "one side" of a die.

My guess is that it's the scrap slug from the screw machine that made the nuts. AFAIK you lose the small end piece that was held in the machine jaws, much like you would with a lathe.

Okay, I'm in ...I'm going with custom fixturing bushings. The bushings fit into holes on a fixture table and the part / weldment is attached to the bushing via a bolt or stud...that's my guess, and I'm stick'n with it!

They look like some type of early version of a nutsert but would need to flattened like a rivet instead of the tool system in place now.

I'll go with "machined part" something like where the original 2 threads in the base metal were stripping out so one cored out a larger hole and welded this in place and bam, new threads and several more of them.

Skate track bearing hubs, could be for conveyor track in some farm implement such as a harvester.

no neat sig line

Is the little ball spring loaded?

Try googling weld in threaded inserts:

not spring loaded

 

[HKlassen]

not spring-loaded

 

[The Cobbler]

my guess a custom machined threaded insert to be welded to something

Okay... that has got to be what these are! Thank you so much for all the answers... Nicely done!!!!!

Is that a detent ball in the end of it?

No. There is a little ball on the underside as you can see, but it is fixed (non moveable)

Are they all the same? or different diameters? I'm sorta thinking some sort of centering device for locating the center of holes for a gasket or something.

 

[MarlynOC]

Dowel setting to set cent of drill for other dowel insert point.

See post 10. Click the link - scroll down a bit and you'll find a chromate finished insert that's a dead ringer for OP's. Stands out from the rest because of its golden glow. No doubt, it's a weld-in threaded insert with a blind hole.

 

[rsanter]

Weld in threaded stand off insert.
Depending on the thread size those can come in handy

 

[BlakeTheCarGuy]

Maybe you could go back to him and ask lol. They look almost like mini bushing press things maybe for something small.

The round thing on the right is a quarter. Your welcome!

 

[SuzukiGS750EZ]

I'm going with some sort of self retaining nut.

Though, it could also be a replaceable part on something that wears frequently like a detent ball or roller type ball, such as on a folding frame lock knife.
