stainless steel pancake head screws, why do screw manufacturers ask this question?

When we consulted the screw manufacturer for stainless steel pancake head screws, and we didn’t have drawings, why did the screw manufacturers ask which ultra low head we are, is the ultra low head, not a fixed head type?

In fact, the reason why the screw manufacturer asks the customer which shape of the  ultra low head in the stainless steel pancake head screws is mainly because the ultra low head is also divided into two types, one is that the edge of the head is similar to C and has a curvature, and the other It is the edge of the head that looks flat. Just like when we are frying eggs, we put the eggs directly into the pot to fry, so the shape of the fried eggs is not fixed, and when we put the eggs in the model to fry, the shape of the fried eggs That is what we deliberately made. The same is true for ultra low head.

The flat edge of the head has a curved ultra low head that is naturally formed during cold heading, while the edge of the head is an ultra low head screw because the mold is controlled during production to control the deformation of the head. The cost of these two kinds of stainless steel pancake head screws is different. Therefore, the screw manufacturer will ask which kind of ultra low head it is.
