Morphology
The compound is directly compositional: 'cap' (a head/cover) + 'screw' (a threaded fastener) yields a screw with a finished/headed top. This noun+noun formation matches common English compounding patterns and is predictable to a learner who knows both constituent meanings, so it is transparent.
Etymology
Cap screw is a name for a screw that has a 'finished head' like a little cap. Picture a screw with a neat 'cap' on top that you drive into a hole made to fit it; because of that capped head it is used to 'hold machine parts together'.
