Best just to get an enlarging lens with standard 39mm leica thread. Confused about the reference to M 30 thread.

The thread screw on this lens is to big, and does not fit! What do I need to mount onto the enlarger so I can use this lens? Or is it easier to just get a lens that has the required M 30 thread screw?
