Synopsis: the
Hexagon wrench or Allen wrench. Common English name "Allen key (Allen wrench)" and "Hex key" (or Hexwrench). In the name of "wrench" means "twisted" movement, which embodies the Allen wrench, and other common tools (for example: Word screwdriver and Phillips screwdriver) the most important differences between, which exert forces on screw Torque, greatly reduce the user's strength. So to speak, in modern furniture industry involves the installation tool, hex wrench is not the most commonly used, but it is the best to use.
In addition, varying according to the shape of the screws, Hexagon wrench can also be divided into flat head Hexagon socket, ball end hexagon and Hexagon three star, and also long Hexagon, long hex and standard hex.
Most commonly used in everyday life of Allen wrench vanadium steel is made up of complex processing, commonly known as (CRV), through a series of heat treatment, hardness is high, price is also very high, relatively speaking, very practical.
Surface there are zinc plated, nickel matte, polished, you can increase the lifespan of products, durable and prevent rust.

Second: the historical
origin of the said Allen wrench, Hexagon socket screws must start. In some non-English speaking countries in Europe, "Allen key" is called a
Hexagon socket wrench (3)
"Unbrako key", this "Unbrako" actually was the original Hexagon screws brands from the United States of SPS companies (Standard Pressed Steel Company) was founded in around 1911. SPS[1] from the company's earlier United Kingdom import a SQUARE HEAD BOLTS, but the price is very expensive, in order to save costs, SPS company decided to manufacture their own. Founder of the SPS h. T. Hallowell says in his memoirs: "we start trying to do something and the United Kingdom as the screw with a square hole, but soon found that the screws in the United States will not be accepted. So we decided to include a hexagonal screw holes. "Hallowell's interpretation of this history is ambiguous, but it was later speculated that the SPS is the SQUARE HEAD BOLTS in order to avoid patent disputes and make modifications. In short, SPS company started producing the new Hexagon screws, and register a trademark called "Unbrako", is taken from "unbreakable" sounds like, which means "unbreakable". Hexagon socket screws after eclipsing the inner SQUARE HEAD BOLTS as the new industry standard, widely used in cars, airplanes, machinery and furniture and other manufacturing industries.
"Allen key" origin
Hexagon socket screws there will need to be compatible with the wrench. "Unbrako" Hexagon socket screw swept the United States in those years, all kinds of wrenches is made, but they do not have a unified name. Until 1943, located in United States, Connecticut's Allen Company for its production of Hexagon wrench are registered trademarks, and named the "Allen wrench or key" with Allen after the company increasingly powerful influence, "Allen key" generic name gradually become a hex wrench.
Three: the advantages of
Hexagon wrench can spread and become indispensable tools in industrial manufacturing, the key is that it has its own unique characteristics and advantages:
1, it is very simple and lightweight.
2, Hexagon socket screws with the wrench between six contact surfaces, full force and not easily damaged.
3, can be used to loosen screws in a deep hole.
4, wrench the diameter and length of the torque.
5, can be used to turn very small screws.
6, easy to make, low cost.
7, wrenches can be used at both ends.
