hex keys
Six-sided socket drivers
Hex keys are L-shaped tools with hexagonal cross-sections, used to drive bolts and screws with matching hexagonal sockets.
The two arms of different lengths allow access to recessed fasteners and provide leverage.
Also called Allen keys or Allen wrenches after a trademark that became generic.
I need the 4mm hex key for this IKEA furniture.
