It should just screw into the lens board, but sometimes there's an adapter to fit a Componon into a 39mm board. Sounds like the threads are binding.

It could be just a bit of corrosion on the threads. CAREFULLY place some penetrating oil around the threads of the lensboard, and let set a few hours.
