HP Shoulder screw source

[slughammer]

Looking to hollow point a few molds and I'm having a hard time finding affordable shoulder screws small enough for the job. I've checked on Amazon, Bolt Depot and Grainger. (I must be missing them).

Looking in the range of 3/32-1/8-5/32 shoulder length. 6-48, 6-32, 8-32 or 10-32 threads.

I have one sample mold, it's a Lyman 358430, the screw is 6-48 thread, 3/16 shoulder Dia and .107 shoulder length.

I would appreciate any sources that have the screws and any recommended sizes from HP molds you may own.

sounds like you need a lathe and perhaps some taps & dies. Another online acquaintance of mine who does machinery repairs tells me he single-points threads on stuff he's working on to about the 80% range, then finishes with appropriate taps or dies. Gives very smooth and accurate threads. He does stuff from over an inch on down to tiny.

HTH!

BillYeah, I'd rather buy screws. I can do it. I have done it for stuff like 1/2-27, .630-36, down to 10-32.
I have looked again at Grainger and have found 10 screws for $22 (plus shipping).

Try these people:

Bolt Depot (https://www.boltdepot.com/Shoulder_bolts_Alloy_steel_black_oxide_finish.aspx )

I have order several items from them. Decent prices and fast delivery.


Hope this helps.

This is where I ordered the ones I used on my HP mold conversions.

Got lots of them in lots of sizes. I actually prefer to buy from Grainger since they have a branch local to me, but McMaster-Carr often has stuff they don't. And sometimes vise versa.

Can you tell me the PN that you went with from McMaster?

I needed some small shoulder screws for a NEI nose pour mold I had. Got them from McMaster-Carr.
