Can the head size of long brass machine screws be customized?

Now, the concept of customization has entered the minds of many people. Even screw fasteners can be customized. Then, the head size of long brass machine screws can be customized?

The head size of long brass machine screw cannot be customized at will. Why is this?

The following may occur if the head size of the long brass machine screws is customizable. One is that if the screw is made cold heading, the head of the screw may not line up. This is because materials have different coefficients of expansion for forming screws, and the machine also has requirements for the range of molding. Therefore, if the size of the head is set too large and too thin, it may not be able to form.

The second is to consider the problem of long brass machine screws in actual use. Sometimes, there will be a screw turned, the head broke. One is because of the material, the other is because of the design of R Angle under the head, too small will cause the screw head does not have enough protection force.
