How diferenciate 5/16 x18 5/16 x14 joints

[Soma]

Hi, I wanna ask how could I diferenciate this two joints. When I see pics on internet I can appreciate witch is one. I know that this is maybe a dumb question.

Thanks a lot.

Usually but not always the 5/16-14 is piloted, however im sure there are some that have piloted the 5/16-18 really not any way to tell but looking at a picture online. If the cue is made out of the United States it might be a good guess that they are 5/16-18

take a ruler and in one inch count the threads. Unless you have a thread gauge. 14 threads per inch or 18 .
