Morphology
head + screwed + on + straight
The phrase literally combines 'head' with the idea of being 'screwed on' (attached) and 'straight' (properly aligned), so the sense 'one's head is properly attached/aligned' can be mentally mapped onto 'having good judgement'. However, this is a metaphorical, somewhat colloquial extension of the literal words and the construction ('screwed on' used metaphorically about the head) may not be fully predictable to an average B1 learner without prior exposure.
Etymology
Head screwed on straight comes from the simple picture of a head being screwed on so it sits straight and works properly. That's why the phrase means someone has 'good judgment' or is 'sensible'.
