The safety of Allen wrench is superior
First of all, because of the non-uniform size standards of Allen wrenches among countries, there are dozens of wrenches with different specifications and sizes. The use of mismatched wrenches may cause damage to tools or screws, which undoubtedly violates the original intention of users. Secondly, due to the current design and materials, repeated use of the wrench is easy to cause damage until the screw can not be rotated normally, which needs to be updated frequently. In addition, the hexagonal wrench of most structures cannot be used in places where the space is narrow or there is a barrier on the vertical line of the construction plane. However, the hexagonal wrench is still widely used by people, and it has been many years since its invention, which has played a great role in the development of human economy and all walks of life. At present, there are no reports of adverse effects on the health of users due to the use of Allen wrenches, and the Allen wrenches are more or less unsafe due to their design needs. However, in view of the scope of users, it can be considered that the Allen wrenches have superior safety. Although the hexagonal wrench has been tested for many years and is safe and reliable, it is not comfortable for the user. The hexagonal wrench has a common holding problem, which usually requires the user to maintain a tense posture. Long-time use will cause fatigue of the hand muscles, which is not suitable for long-term use. Moreover, the material of the holding part needs to be improved, and the plastic or metal part of the holding part has poor hand feeling, which may cause hand slipping, so it is recommended to use rubber material. As a basic tool, the Allen wrench has excellent health and safety, but its efficiency and comfort are not optimistic. It is both love and hate and needs to be improved.
