Tips: What is a hex key?
An Allen wrench, commonly known as the Allen key or Hex key, is one of the most common hand tools. The Allen key is an indispensable hand tool in daily life because it reduces the user's strength by applying torque to the screws.
After heat treatment, the hardness and strength of hex key are greatly improved. The use of the Allen wrench should be in accordance with the size of the hexagon bolts, and the Allen wrench should be fully inserted into the hexagon bolts and force evenly.
The hex key can be widely used and has become an indispensable hand tool in the manufacturing industry. It has many advantages:
- Low production cost, easy to operate;
- There are six contact surfaces between the hexagon screw and hex key, which are fully stressed and not easy to be damaged.
- Both ends of the spanner can be used to turn the screws in the deep hole.
- The diameter and length of the hex key determine its torque, which can be used to turn very small screws, very practical and useful.
In addition, there are a lot of precautions for the use of hex keys.
The hex key with single head can only screw or unscrew bolt head or nut of one size, and the double head can only screw or unscrew bolt head or nut of two sizes. When using the hex key, please pay attention to choose the appropriate specifications and models to prevent the hand from slipping and hurting.
