Morphology

pin + wrench

The noun-noun compound is directly compositional: a 'pin wrench' is readily inferable as a type of wrench that involves a pin, combining 'pin' (small slender fastener) with 'wrench' (tool to grip and turn). The technical detail about a projecting pin fitting into a socket is a domain-specific elaboration but does not prevent a B1 learner who knows both constituents from understanding the basic meaning.

Etymology

The tool name pin wrench comes from its simple shape: a wrench with small pins that fit into holes or sockets on a part so you can 'turn' or 'unscrew' pieces that a normal wrench cannot grip.
