At least your part has actual threads on it. I got a Stanley (MADE IN CHINA) coping saw the other day from McMaster, that exploded when I tried loosening the handle to take the saw blade out of the frame. 
About one and a half threads holding it together. The rest of them were simply not there on the MIM (metal injection molding) blade retainer. It looked like the mold halves were not aligned properly and the crest of the thread on the left side - aligned with the root of the thread on the right side.
So when they forcefully screwed the handle on, it stripped off all the threads but the last one or two.
