hex wrench
Six-sided tool
A hex wrench is a small L-shaped tool with a hexagonal cross-section, used to drive bolts and screws with matching hexagonal sockets.
The shape allows torque in tight spaces.
Also called an Allen wrench or Allen key after a trademarked brand name: I need a hex wrench to adjust the bike seat.
