Manufacturers of hex keys (Allen wrenches) emphasize that hex keys exert force on screws through torque, significantly reducing the effort required by users, making them an indispensable tool in industrial manufacturing. Most manufacturers of hex keys believe that the most significant difference between hex keys and other common tools (such as flathead screwdrivers and Phillips screwdrivers) is that hex keys exert force on screws through torque, greatly reducing the effort required by users.

It can be said that among the installation tools involved in the modern furniture industry, hex keys, although not the most frequently used, are certainly among the most effective. The reason hex keys have been handed down to this day and have become an indispensable tool in industrial manufacturing lies in their unique characteristics and numerous advantages:

1.They are simple and lightweight.

2.There are six contact surfaces between the hex screw and the wrench, ensuring sufficient force application and resistance to damage.

3.They can be used to tighten screws in deep holes.

4.The torque of the wrench is determined by its diameter and length.

5.They can be used to tighten very small screws.

6.They are easy to manufacture and cost-effective.

7.Both ends of the wrench can be used.
