A fastening bolt designed to transmit mechanical power or force in machinery.
Compound of 'drive' (Old English 'drifan') and 'bolt' (from Old Norse 'bolti', meaning a short thick arrow or metal pin). Used in engineering to describe bolts that actively transfer rotational or linear force.
Drivebolt is a perfect example of technical vocabulary—engineers needed a precise term for a bolt that doesn't just hold things together but actively transfers power, so they literally combined the words to describe its function.
