I'm trying to create a series of cylinders (25mm diameter and 3mm thick walls, the rest hollow) that can all be screwed together to create a longer cylinder. I have the external threads down, but I can't seem to create a cylinder with internal threads that ends up with the correct diameter. Image attached of what I have so far. I'm sure it's something simple, but I'm still learning Fusion. TIA!

There is no standard metric thread which will give you a smooth 19mm bore and a smooth 25mm outer surface. 22mm - 2 comes close.
Decreasing the pitch to 0.5mm will work:
So the questions is do the inner and outer diameters have to be same for both?

22x1.5 is standard fine pitch. It would probably still need extra support on the inside.
I'd be more inclined to use a coupling between each cylinder instead of having male and female threads on each cylinder:
This would probably be a good excuse to use the Simulation workspace😀

Would you mind sharing how to create the coupling? Still getting my bearings with Fusion,
Each of the parts are just simple revolves from one sketch. Using the centerline type allows entering dimensions for the diameters instead of the radii.

p.s. Only one of the cylinders needs to be modeled. Just make copies and use joints to connect them to the coupler.
