The origin and advantages of allen wrenches
source:Industry News release time:2021-04-21 Article author:Rosit Popular:Air band saw
Speaking of the origin of the Allen wrench, we must start with the Allen screws. In some non-English-speaking European countries, people call "Allen key" "Unbrako key". This "Unbrako" is actually an early brand of hexagon socket screws, founded by the American SPS company (Standard Pressed Steel Company) around 1911. SPS company imported a type of socket screw from the UK earlier, but the price is very expensive. In order to save costs, SPS company decided to produce it by itself. HT Hallowell, the founder of SPS, said in his memoirs: "We started to try to make some screws with square holes like the UK, but soon discovered that this kind of screws would not be accepted in the United States. So we decided to add six screws to the screws. Angular holes.” Hallowell’s interpretation of this history is ambiguous, but according to later generations, SPS has made changes to avoid patent disputes with internal four-corner screws. In short, SPS company began to produce this new hexagon socket screw, and registered a trademark called "Unbrako", taken from the homonym of "unbreakable", which means "unbreakable". Later, the hexagon socket screws gradually replaced the socket screws and became the new industry standard, which is widely used in the manufacturing industries of automobiles, airplanes, machinery and furniture.
The origin of "Allen key"
As soon as the hexagon socket screw appears, it needs a matching wrench. In those years when "Unbrako" hexagon socket screws were popular in the United States, various wrenches were manufactured, but they did not have a unified name. It was not until 1943 that the Allen company located in Connecticut, USA, registered a trademark for its Allen wrench or key, and named it "Allen wrench or key". Later, with Allen's growing influence, "Allen key" gradually became a hexagon socket. The common name of the wrench.
Advantages of Allen Wrenches
The allen wrench can be passed down to this day and become an indispensable tool in the industrial manufacturing industry. The key lies in its uniqueness and many advantages:
1. It is simple and lightweight.
2. There are six contact surfaces between the hexagon socket screw and the wrench, which are fully stressed and not easily damaged.
3. It can be used to screw the screws in deep holes.
4. The diameter and length of the wrench determine its torsion force.
5. It can be used to screw very small screws.
6. Easy to manufacture and low cost.
7. Both ends of the wrench can be used.
