The unsung wrench that builds your furniture, then vanishes into the carpet forever.
means A small L-shaped tool with a hexagonal cross-section, used to turn bolts and screws that have a matching six-sided socket in their heads.
from Named for the Allen Manufacturing Company of Hartford, Connecticut, which popularized the hex-socket screw and its matching wrench in the early 20th century — "Allen" being a trademark that escaped into everyday speech, the way "hoover" or "biro" did. Elsewhere it's the more neutral "hex key." The tool's defining shape comes from the hexagonal recess it fits, which grips on six sides rather than the slot or cross of ordinary screws — handy for tight spaces and flat-pack furniture alike.
