The word "screw key" does not have a specific etymology because it is a combination of two separate words, "screw" and "key", each with their own origins.
The word "screw" dates back to Old English "screwan", which means "to twist or turn". It is derived from the Proto-Germanic word "skruvis", meaning "a metal rod with a helical ridge". The term "screw" came into use in English around the 15th century to refer to a fastener with a helical thread.
The word "key" originated from Old English "cǣg" or "cēg", which means "a device used for turning a lock". It is believed to be derived from the Proto-Germanic word "kaigo", meaning "key" or "bar".
