Difference between 3/8-10 and 3/8-11

Too many bastard 3/8 10 before you even deal with 3/8 11.
My tap only needs .295" sized hole.
There are also two kinds of 3/8 10 flat bottom floating around.
BCM's version has a smaller minor.

There are a few 3/8 11 as well.
The SW is less than .308 minor, but the most commonly used one has .308.
I didn't want to deal with that . Mine has a true .3125 minor.
Sugar Tree's 3/8 10 has a true .3125 minor as well.
Barenbrugge's 3/8 is actually a little smaller .

In a perfect world, all 3/8 screws would have a .3125 minor .
Of course, they are really not 3/8 because they are some .381" major.

Don't forget the delightfully quirky 3/8-11.5 :D
 
If 3/8 does not mean 3/8 why would that be stated as a screw diameter? it either is or it is not. 10 or 11 is just supposed to mean one more thread per inch period. Why would there be any confusion on stated numbers?


Because in Pool cues, the fractional number is a point of reference. In my shop, they are referred to by thousanths by threads per inch. It's tuff action and can be a pain in the ass.
People call Bludworths joint screw a 3/8x11.5
And Cognoscenti's a 7/16x11
I assure you they are not.
I have 3/8x10 screws that range from
Approximately.352x10 to .372x10.
Cue makers right to individualism is SPECIAL
HAHAHAHA
 
The subject of the screws variable's is my curse. It's brutal. Here's another example. They're pretty much endless. I modified this uni loc for an extension because first:
I don't like the aluminum one's for extensions.
Second:
I don't like the size it's offered in. Different taps and split dies are the nuts if you are able to use them.

Maybe Kim will chime in, I certainly am not an expert on anything, could be mistaken, which was why I phrased my comment in the form of a question. Sorry for any contusion

I for one. Would be thrilled if KIM and others posted pictures to help explain differences in joint screws.
Absolutely thrilled!
 
This thread is really intresting, as standard appear to have no real true standard. Recall when all you need to know was if a screw, nut, or bolt was metric, or american standard.

The the guy at the hardware store point you to the righ bin of nuts, bolts, screws, etc.

Exactly correct. Who would have ever thought Cue makers were anything but standard.
Hahahahahahaha

I am always thrilled when I see pictures in the cuemakers section from anyone to be honest, much easier for me to grasp what is being discussed or understand the context(since I am not a cuemaker or familiar with the tools of the trade).
When I was reading this thread, the pictures you had posted came right to my mind, so thank you for taking time to help others understand.

Well all I know is all Cue Pins of a given size are not created equally. Assume some Cuemaker even fabricate their own so customers are tied to them for repair work.

Like Lockeed-Martin did with Tool to work on F-35, they are special sizes that Lockeed Marten own patent on.:)

Your welcome. That's why I post them. It's not as simple as most people think it is.
 
Here's another one. 3/8x11. I didn't put the measurements but both are in the Industry. The one on the left is for Southwest. You can clearly see a difference in the screws and the taps.
This is fun stuff.

And the famous 3/8x10 not counting the acme but I did include the 3/8x10 used in Mohawk cues. All they could tell me when I had the tap made was, it was a negative thread. I have no clue what that really means but it's different than the so called standard.

That's crazy to see all the different pins, so when someone says they have a 3/8-10 pin, do you ask which one right off the bat? I have to wonder, how that works, do most cuemakers have taps for the various sizes 3/8th pins?

.Tuff question.
Some think it matters and some don't. The one's who live thread, adjust if they choose to measure. Because I worked a lot of tournaments in the 90's and offered shafts at tournaments. I had to have taps to accommodate the different threads. I have quite a collection across the board. The goal working tournaments was, offer as much as you could and make as much money as you could, There! Take nothing home if you didn't have to. Even if it was just joint protectors out of delrin which is why I had split dies made.
