Allen key
An Allen wrench, Allen key, hex key or hex head wrench is a tool used to
drive screws and bolts with a hexagonal socket in the head.
Some of the advantages of this format of tool are:
-Six contact surfaces between bolt and driver
-Contact surfaces of the bolt are protected from external damage
-The bolt can be inserted into its socket using the key
-Torque applied constrained by the length and thickness of the key
-Very small bolt heads are accommodated
-Can be used with a headless screw
Using a single tool instead of many others reduces tooling costs for the
manufacturer and is more convenient for the end user. Many manufacturers
have adopted hex key bolts for assembling bicycles or for self-assembly
furniture.
"Allen wrench" was originally a trademark of Allen Manufacturing Company
in Hartford, Connecticut in 1943. In Europe, it is usually known as an
"Unbrako key" (also often misspelled as "Umbrako"), which is a brand
name established in 1911. The brand is owned by SPS Technologies.
