Countersunk Screws
A countersunk screw, also known as a “flat-head screw,” sinks into a surface and rests flush in materials. Similar to other screws, a countersunk head screw has ridges that twist into a material to provide fastening power. Countersunk screws have a flat head instead of a rounded or semi-rounded one. Stainless Steel Countersunk Screws is a type of fastener that is sits as close to the surface of the material it occupies. Typically, Stainless Steel Countersunk Wood Screws are used in such a way that they can be covered easily with either a screw cap or piece of wood.
