Countersunk screws differ in the sense that they have a flat head. Most screws, of course, have a rounded or semi-rounded head.
Therefore, when you drive a countersunk screw into an object or surface, the head will sink so that it’s flush with the respective material. They feature a flat head that tapers along the shaft. They are called “countersunk screws” because they “sink” into objects and surfaces. Countersunk screws are simply characterized by their flat head, which allows them to sink into objects and materials.
The countersunk screw also known as a flat-heat screw is a type of screw that’s designed to rest flush with the object or surface in which it’s inserted.
