Morphology

unthreaded = threaded (transparent) = un + thread + ed

The meaning is clearly derived from 'threaded' with the prefix 'un-' indicating the absence of threading.

Etymology

Unthreaded comes from un- 'not' and thread, which also names the spiral 'groove' on a screw that looks like a wrapped string. That's why an unthreaded bolt or pipe is 'smooth' and has no spiral for screwing parts together.
