Why is the long hex screw always hexagonal?

Why do you rarely see the triangular screws, the four corners, the seven corners, the seven corners, the eight corners… Why is the long hex screw?

In “100,000 Why”, it is said that the long hex screw can be restored by 60 degrees. If the space is relatively small, the screw can be installed as long as the wrench can be turned 60 degrees, which is the result of the compromise between the twisting angle and the side length. Therefore, the hexagonal long screws are commonly used.

If it is a square, the side length is long enough, but it needs to be screwed 90 degrees to restore the image, which is not suitable for small space installation;

If it is an octagon or a decagon, the angle of the graphic reduction is small, but the side length of the force is also small, and it is easy to round;

If it is a single-sided side screw, then the two sides of the wrench are not parallel. Very early, there is only a fork-shaped wrench. The singular-side wrench head is a trumpet-shaped opening, which seems to be unsuitable for the force…

Also, note that the head and handle of the wrench also have an angle. If space is smaller, turn the wrench forward and backward, as if space is only 40 degrees or so.

But now there are socket wrenches, plum wrenches… the minimum angle of twist can be 15 degrees.

Of course, for the purpose of preventing misoperation or anti-theft, there will be more exotic bolts. For example, such a triangle can only be opened with a specific tool like unlocking. Generally, the wrench can be screwed, but the triangle cannot be twisted. Inconvenience is its selling point. The inner pentagonal screw on the Apple phone is also for the same purpose.
