I just purchased a brand new Zeus which is also a 3/8-11 the same as my Mohawk cues. They are all 3/8-11 but you can not put the Mohawk on the Zeus or vice versa. They will start and go maybe 1 full turn and that's it.
You can get a 3/8-10 on if you lube the threads and work it down and off many times. As I said I did it in the 90s and used that same shaft in it for a good 8 years.
