It looks like a 5/8-18. Don't have a set of thread gauges at hand though.
I found on TheCustomSaberShop forum it could be also a 9/16-20 tap.
In France, I succeded to mount this button on a cork of plumbing 12 mm diameter - 12 x17 :
It was a success for my Mara Jade lightsaber :
Now, I try to tap a stainless tube (like Graflex) to mount a red button on it.
I just prefere to be sure because these kind of tapes are quite expensives ^^
