Morphology

hex + key

The compound is compositional: 'hex' (hexagonal / six-sided) + 'key' (a small tool) directly yields the idea of a small tool with a hexagonal cross-section for turning screws. Although somewhat technical vocabulary, the meaning follows standard word-combination logic and would be derivable by a B1 learner who knows both constituents.

Etymology

Hex key: The name hex key comes from hex meaning 'six-sided' and key because the tool fits into a screw head like a key fits into a lock. So a hex key is a small L-shaped tool whose six-sided end turns those matching screws.
