| Beispiele/ Definitionen mit Quellen | This tool is also commonly referred to by various trademarks or brand names. "Allen wrench" was originally a trademark of the Allen Manufacturing Company in Hartford, Connecticut, taken out in 1943. In non-English speaking parts of Europe, it is usually known as an "Unbrako key" (often misspelled "Umbrako"), which is a brand name established in 1911. The brand is owned by SPS Technologies. In Germany and the Netherlands, this type of screw is known by the name "Inbus", after the company that patented them in 1936, Bauer & Schaurte Karcher in Neuss (Innensechskantschraube Bauer und Schaurte). (It is still known as an Inbus-key—often misspelled as Imbus-key—in parts of Europe.)
