Morphology

Unbrako + wrench

This is a straightforward brand-name + noun combination: if a learner recognises that Unbrako is a maker (proper name) and knows 'wrench' they will infer it denotes a wrench made by Unbrako. The exact technical detail (hexagonal cross-section) is specialized knowledge, but the overall meaning 'a type/brand of wrench' is compositionally transparent.

Etymology

Unbrako wrench comes from the company name Unbrako, which made a strong tool with a six-sided end that fits into 'Allen' screws. So people began to use the brand name for that kind of wrench, and today it means the tool used to turn bolts and screws with six-sided sockets.
