What do you think?

I think what happened is maybe the cue maker screwed a hash pipe into the butt threads by accident. Did you check under the buttcap, maybe its supposed to be smoked?
I don't know what to think . That's why I asked. It a unique looking pin but is it a standard thread like a radial or 3/8x10?
It's a standard joint screw for Astle cues out of Maine
Thanks. It's 3/8 ×10 modified according to Astle. I found his Facebook page afterwards. What the difference between a 3/8×10 and a modified? Will a 3/8×10 shaft fit on a modified or vice versa?
Different minor diameter, a lot different. 3/8-10 is stronger because it actually engages on the pitch diameter, like V threads are suppose to do.
I have no idea. We Cue makers and Cue mechanics deal with so many different joint screws. I personally stopped caring eneogh to ask.
Right to Individualism.
I just mosey along.
Man that's good work.
Which one's the Astle?

In general, the 3/8-10 modified have a flat-bottom diameter, and the threads don’t form a standard V. I have no idea why any cuemaker started making this kind of thread. I’m sure there was some thought to it, like maybe it had less chance of stripping the the female-threaded shaft. It’s strength as a thread would depend on the mating shaft thread, but it looks like it would be weaker than a standard V thread. But, cues don't need much strength to keep them together I suppose.
The fancy lead in profile looks to be for aesthetics. The initial diameter looks to be (from a thousand miles away) the same diameter as the minor diameter, so it should act like a lead in.

The lead isn't even a thread, if you look hard the major (and minor) sections are straight, no pitch.
Nice looking thing, although I wish there were a bit less different pins out there for cues. The 3/8x10 is probably the best one, to my untrained seat of the pants thinking. Sharp edges, nice spiral to keep the threads locked tight. I think my favorite hitting cues have all been 3/8x10 designs. Looks classier and higher end than the smaller ones like 5/16x18
Is there some kind of bushing in there? Just air?
I think the very tip of the screw just aligns the joint when screwing it together.
I wouldn’t expect any angled thread in the front lead/pilot section.
More surface contact was the reason for DPK starting it.
The radial was then started by Stroud.
