[What is a countersunk bolt?]
It has a countersunk head, which allows the fastening surface to be made flush by opening a counter bore on the mating material and fastening. Therefore, it is often used in places such as hinges where you do not want bolt heads to protrude.
It is similar in shape to a small crosshead countersunk screw, but since a hex wrench is used for the countersunk bolt, it can be used in a place where it needs to be tightened more securely.
