FWIW, with a 10 ton ram, and probably all 2" o.d. rams.
The thread is 14 TPI.
As nobody invented a pipe thread, metric manufacturers have used National Pipe and made it a straight taper-less thread. That is what this cylinder uses, and a pipe coupling will work, but because of the taper it does not screw in more than 5/8 inch. I don't consider that enough on a taper.
I have threaded a hole in a 5"x12"x1" bar to screw the cylinder into, and slotted each side for pulling. Works well.

The virtue is always a cover for the sin. That's the key to understanding the modern left. Whatever they're accusing you of doing, they are doing themselves but more enthusiastically. And that's definitely the story of Justin Trudeau. Tucker Carlson
