Japanese Belinai Hex wrench

Allen wrenches are also called Allen wrenches. Common English names are "Allen key (or Allen wrench)" and "Hex key" (or Hexwrench). The "wrench" in the name stands for "twisting" action, which represents the most important difference between Allen wrenches and other common tools such as flat screwdrivers and Phillips screwdrivers, which apply force to the screws through torque, greatly reducing the user's force intensity. It can be said that among the installation tools involved in the modern furniture industry, Allen wrenches, although not the most commonly used, are the best to use.

The Allen wrench has survived to this day and become an indispensable tool in industrial manufacturing, the key lies in its own uniqueness and many advantages:
1, It is simple and lightweight.
2. There are six contact surfaces between the Allen screw and the wrench, which are fully stressed and not easy to damage.
3, It can be used to tighten screws in deep holes.
4, The diameter and length of the wrench determine its torsional force.
5, Can be used to tighten very small screws.
6, Easy to manufacture, low cost.
7. Both ends of the wrench can be used.
