I. introduction:
Allen wrench is also called Allen wrench. The common English names are \"Allen key\" and \"Hex key\" (or Hexwrench). Said the \"wrench\" in the name of \"twisted\" action, it embodies the inner hexagon spanner and other common tools (such as a screwdriver and phillips screwdriver), one of the most important differences between it through the torque applied to the screw force, greatly reduces the user's strength. It can be said that in the modern furniture industry involved in the installation tool, the hexagon wrench is not the most commonly used, but it is the most useful.
In addition, according to the shape of the screw, hex socket wrench can also be divided into flat head hex socket, ball head hex socket and star Allen, and size also has extended hex, long Allen and standard socket head.
Application in daily life the most common inner hexagon spanner is commonly done by winding vanadium steel processing, commonly known as (CRV), after a lot of heat treatment, hardness is high, the price is very high also, relatively speaking, is very practical.
The surface is generally galvanized, nickel-coated, polishing treatment, can increase the use of products, durable, prevent rust.
The hexagon price and packing quantity are as follows:

Two: the history

When it comes to the origin of hexagon wrench, we must start with the inner hexagon screw. In some non-english speaking countries in Europe, \"Allen key\" is called. 

Hexagon socket wrench (3 pieces)
\"Unbrako key\", the \"Unbrako\", was actually the original hexagonal screw brand created around 1911 by the Standard Pressed Steel Company. SPS[1] had previously imported an internal four - Angle screw from the UK, but the price was very expensive. In order to save money, the SPS company decided to produce it itself. H. t. Hallowell, the founder of SPS, said in his book: \"we started trying to make screws that were as square as the UK, but soon found that the screws would not be accepted in the United States. So we decided to add hexagonal holes to the screws. Hallowell's explanation of this history is vague, but it has been speculated that the SPS were modified to avoid patent disputes with the four corners. In short, the SPS company began to produce the new hexagon screw and trademarked the name \"Unbrako\", a homonym for \"unbreakable\", meaning \"unbreakable\". After that, hexagonal screws gradually replaced the inner four Angle screws as the new industry standard, which is widely used in automobile, aircraft, machinery and furniture manufacturing industries.
\"Allen key\".
The inner hexagon screw needs to be matched with the wrench when it appears. All kinds of wrenches were made in the years when the \"Unbrako\" hexagonal screws were popular in the United States, but they did not have a uniform name. Until 1943, is located in Connecticut Allen company registered trademark for the production of Allen key, named \"Allen wrench or key\", after with Allen company growing influence, \"Allen key\" gradually became common name of Allen key.

Three: advantages
The inner hexagon wrench can be handed down to today and become an indispensable tool in the industrial manufacturing industry. The key lies in its unique features and many advantages:
1. It's simple and light.
2. There are six contact surfaces between the hexagon screw and the wrench, and the force is sufficient and not easily damaged.
3. It can be used to twist the screws in the deep hole.
4. The diameter and length of the wrench determine its torque.
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.
Name of product: hexagon socket wrench.
The supporting model: 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, 17mm, 19mm, 22mm, 27mm.
