Stainless steel countersunk head screws with hexagon socket. Also known as a flat heat screw, a countersunk screw is a type of screw designed to rest flush with the object or surface in which it is inserted. They are called "countersunk screws" because they "sink" into objects and surfaces. They feature a flat head that tapers along the shaft. So when you insert a countersunk screw into an object or surface, the head sinks so that it is flush with the respective material. Specifications: Type: countersunk head with hexagon socket.
