Morphology
This is a straightforward noun–noun compound: a 'wrench' (tool) whose 'end' is 'box'‑shaped (i.e., a closed/ring-like end that fits over a nut). The meaning is directly compositional from the known parts and follows ordinary English word‑building patterns, so a B1 learner who knows the constituents can reasonably infer the sense.
Etymology
Box end wrench is named for its closed, box-like end that fits over a nut like a small box. Because the box surrounds the nut on all sides, it can 'hold' and turn the nut firmly, so it won't slip when you tighten or loosen it.
