I've seen these things somewhere - I need a couple of 3/16 pins, 1.5 inches
long, aprox, with larger threads (like 1/4-20) for 1/4 inch or so on one
end, and slotted or something on that end - the idea is to have a hole that
is threaded for a little bit, then narrows down to the root diameter - these
pins will go into the hole and act like a setscrew on the item at the other
end of the hole - I've seen these somewhere - what are they called?

(I hope that description makes sense - sort of a shoulder bolt in reverse -
threads near the head, then a long unthreaded section that is no larger than
the threads root diameter)

Dog point set screw, although standard ones are more thread, less
point.

the longest "dog point" I could find was only about 1/4 inch - might there
be another name for something where the 'dog point' is over an inch and the
threaded part is 1/4 or 3/8 inch? If I could get daschund point #10 set
screws, that would be perfect

You only need a couple of these, right? Why not just make them? Seems
like a few minutes and a hunk of allthread ought to get it done.

Bill,

You might well have seen something made to OEM specs for a specific
application. I've seen them too, and never has the straight portion with
the same black oxide as the threaded portion. I suspect they are made as
needed for particular applications. I have made some myself...

I tried turning some cap screws and it didn't work well - from my
calculations, if I stick with #10, I need four of them if they are hardened
(e.g. #8) but more if they are not (#5), and it would be a challenge to use
more than 4

Did you try boring a hole in a set screw and superglue-ing or
brazing in a dowel pin?

that is one alternative that I've considered - though set screws are
typically hardened, one would hope that with carbide they could be drilled
successfully

I see this type of thing all the time on older guns, usually the
unthreaded shaft is used for pivoting parts on. I know of no standard
hardware in that configuration, were made as needed for the guns as
designed. I have seen threaded-end dowel pins, but the threads are
ground with the pin surface as the major diameter. Would a two-piece
approach work? Flat-tipped set-screw bearing on a smaller dia. pin?
Getting the pin out of a blind hole might be interesting, though.

I've made a bunch of brass dog points on steel 1/4-20 setscrews
when I couldn't get any locally. Made a fixture to hold the
setscrew with a jam screw behind it to do the drilling on the
lathe. Press-fitted the brass parts. Worked a charm.

indeed, the only reason I want the threads is to get the pin out of a blind
hole.

Pull dowels have female threads for extracting them from blind holes.

yes, indeed, but not in 3/16 diameter - the problem is that these have to go
"sideways" through 3/8 plate, so I can't make them larger than about 3/16 or
I sacrifice strength in the plate

[pyotr filipivich]

the question is raised - "help, what do you call a pin with threads?"

And my smart ass answer is "A very tiny bolt?"
