In pursuit of headless set screws with a better drive than a straight slot, Hallowell said, SPS had sourced set screws of square-socket drive from Britain, but they were very expensive.

Explained by the geographical and commercial history of the drive type's development, the term "hex key" is best known as "Allen" in the UK, Australia, Canada and the USA (The “Allen” name is a registered trademark, originated by the Allen Manufacturing Company of Hartford, Connecticut circa 1910, now owned by Apex Tool Group, LLC, which was acquired by Bain Capital in 2014), and also in Spain (llave Allen pronounced with Spanish double L, /ʎaβe aʎen/), Because hex-style hardware and tools are available in both metric and Imperial and customary sizes (the latter sometimes labelled "SAE"), it is also possible to select a tool that is too small for the fastener by using an Imperial/customary tool on a metric fastener, or the converse.
