Do you have an adjustable die wrench? If you look at some of the dies (not all, but some) the round die is split, like a “C”, and there’s a teeny little screw in there to tweak the gap in the “C”. Which tweaks the size of the thread, ever so slightly. If so, yours could be mis-set. Probably too far open. (There are reasons why you might want to do that, but unfortunately, they don’t normally mention that the dies can be tweaked, so nobody realizes what’s going on if they get out of adjustment.) Sometimes there’s an adjustment screw on the die wrench too, so you can tweak it twice, if you’re not careful.)

1.9mm is a strange size as most metric t and d’s are either 1. 1.5 2 etc in finished thread size. Then you need to look up engineering tables that give you the material thickness to start with for the male, ie bolt and and the drill size for the female to use.

I am cutting threads like a nut and bolt for threaded earrings. Each piece comes out nicely, sharp clean cuts. The problem is when I screw them together they round. The pieces are not heat treated or hardened. Is that the problem? I’m mostly doing 14kt and casting both pieces, but it seems to happen in any metal so I’m sure it’s me. I’m using the jewelry tap/die tool, a little burr lube, the correct size, both pieces are 1.9mm. I’ve seen some other pieces that others have done and they are crisp.

I have never tried threading gold before but I have Sterling. I find Sterling threads pretty well but I have only planned on the threads to have a one way application. I occasionally make small pendants for funeral ashes and once the container is threaded shut I slightly deform the device to keep it threaded tight.
