good old reliable 3/8ths inch diameter x 10 threads per inch pins, are they all the same?
Question 3/8ths x 10tpi Pins
- Thread starter jackiestax
- Start date
mostly they are standard style threads, however, there are some that are a bit different. The pins Thomas Wayne uses are 3/8 10 but the grooves are bigger and flatter. Dave Kikel used an acme pin on some cues that has big squared off threads. These are a couple of examples of different ones I have seen.
This, thanks to Mr. Dzuricki, will show you the difference between the two types of 3/8-10 joint pins: http://www.dzcues.com/images/mod-pin.jpg

hoped someone would post some pics, thanks. (thought there would be several to choose from?)
some of the guys i know are working with Billet Alluminium, any feedback here will be greatly appreciated.

I bought a Predator Z 3/8x10 shaft to go on a Sigel cue and I could not get it on. It fit my Lambros fine as well as my Carmeli, but not the intended butt. I took it to Bob Frey and he drilled in a little more and it now fits fine. I was a little surprised that the shaft did not fit at first as the pins look identical.
Since were on the subject of 3/8x10 pins,, I have a question ,, in a common production shaft how far in, is the joint bored out on them
??
I ask cause Ive seen some 3/8x10 pins that were left longer than others on the butt,, and wondered if this could pose a problem for the avg. production shaft joint length ??

anyone have or use anodized steel 3/8 x 10 pins or carbon type? i know there's more out there.
Would the modified pin fit the standard 3/8x10 pin? Or either way around?
Although the major diameter (approx. 3/8") is the same for both, the modified 3/8-10 screw has a larger minor diameter (the solid center part of the screw at the bottom of the threads) than does the regular 3/8-10 screw.
So if the shaft is drilled/bored/tapped with close tolerances for the regular screw, the modified screw will be too thick on the minor diameter to fit into the hole. It will work the other way around, however -- the regular 3/8-10 screw will fit into a shaft drilled/bored/tapped for the modified 3/8-10 screw. The fit may just be a bit "sloppy" until the threads draw the shaft joint face tight against the butt joint face.
Also note that it's not much of a job for a cuemaker or cue repair person to enlarge the minor diameter a bit on a shaft made for the regular screw so that it will accept the modified screw.

Aha. I have had shafts for modified screws from quite a few different makers, and they have all accepted the standard (McDermott type) 3/8-10 screw, so I have not encountered that problem. Which modified screws (source/maker) have threads of less than 60 degrees?
