Morphology
lag + screw
The headword 'screw' clearly marks the compound as a type of fastener, so a learner who knows the constituents would at least infer it refers to a kind of screw. However, the modifier 'lag' does not transparently convey the specific properties (heavy‑duty, square/hex head, driven with a wrench) for an average B1 learner and its relation to those features is not obvious. Because the category is clear but the specific sense of 'lag' is not predictable, this is semi-transparent.
Etymology
Lag screw may come from old building work where big screws were used to hold the 'lagging', the heavy cover, on hot pipes and boilers, so the name joined lag and screw. That's why lag screw now means a heavy-duty screw you drive with a wrench to hold heavy wood or metal in place.
