Joint Pins - What and why

PickPocket · 2022-01-25T20:25:10+00:00

What is the difference between joint pins. Obviously threads per inch etc... I'm not asking the difference in physical properties, I'm asking why use one over the other.. What are the MAJOR differences? Why use a Radial over a 3/8-10? Why use 5/16-14 over 18? Is one QR better than another? if you were handed a cue already assembled and hit balls with it, could you determine it's pin type before seeing it broken down?
