one: Introduction:
within the six corner of the wrench also called Alan 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. It can be said that in the modern furniture industry is involved in the installation of the six corner wrench, although not the most commonly used, but it is best to use.
in addition, according to the shape of the screw is not a, inner hexagon spanner can also be divided into flat head inner hexagon, ball head hex and star type hexagon three, and size of the lengthened hexagon, long inner hexagon hexagon and standard.
in daily life, the most common application of the inner hexagon spanner is generally by collateral vanadium steel processing, commonly known as (CRV), after several rounds of heat treatment, hardness is very high, price is very high, relatively speaking, very practical.
surface generally have galvanized, nickel plating, polishing treatment, can increase the use of products, durable, prevent rust.
this product is high quality low vanadium steel (CRV) material products, high hardness, high frequency quenching, high hardness, abrasion resistance. Surface phosphating treatment, not easy to rust. Durable.
two: history
said that the origin of the six angle wrench, we must start from the six angle screw. In some European non English speaking countries, people called "Allen key"
hexagon wrench
"its key", the "its" is actually the first Hexagon screws brand, by the SPS company (standard pressed steel company in about 1911 was founded. 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". After the six angle screw gradually replaced the internal four angle screw into a new industry standard, widely used in automotive, aircraft, machinery and furniture and other manufacturing industries.
"key Allen" the origin of the
within the six corners of the screw a need to be matched 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, Allen, Connecticut, was registered as a trademark of its six corner wrench, named "wrench or key Allen", and later with Allen's growing influence, "key Allen" has become a general name for the six corner wrench.
three: the advantages of
in the six corners of the wrench can be spread to date, and become an indispensable tool for industrial manufacturing, the key lies in its own unique advantages: 1
, it is very simple and lightweight. 2
, there are six contact surfaces between the inner six angle screw and the wrench, the full force and not easy to damage. 3
, can be used to tighten the screws in the deep hole. 4
, the diameter and length of the wrench determine its torsional force. 5
, can be used to tighten the screw is very small. 6
, easy to manufacture, low cost. 7
, both ends of the wrench can be used.
