Thread identification

On what? barrel end?

Do you own a digital calipers?

If so measure the OD and count how many threads per inch / 25mm there are. If you only have 10mm of threaded end how many threads per that dimension and tell us. From that we can look up the tables. If we also know what use then that is a cross reference. so 1/2inch OD 28 threads for say a 30cal rifle suppressor would be expected.

Yep that if you have calipers, measure od and measure the tops of the threads over as many as you can but say 5 or 10 to keep the maths simple.
