Why is there R Angle under the head of phillips truss head self tapping screws?

When we look at the phillips truss head self tapping screws head below, sometimes we can see the obvious R Angle, so why there is R Angle under the head of the screw?

phillips truss head self tapping screws

The R Angle is set under the head of phillips truss head self tapping screws to protect the head of the screw from being broken when it is twisted. There is an R Angle under the head. The head diameter is generally large, and the rod diameter will be set when it is large. Or the groove is a little deep, in order to prevent the screw in time will break, will set the R Angle under the head, or change the screw head thickness, rod size, etc.

 

However, some customers feel that adding an R Angle under the head makes it inconvenient for them to use it with the flat washer. Because their flat washer is purchased in accordance with the standard size, and once the R Angle is added under the head of the screw, there will be a mismatch when using.

In this case, either change the inner diameter of the flat washer, or do not have the flat washer, or change the head to a truss washer head, which can also save the flat washer.
