Flush-head fasteners are mechanically pressed through a hole in sheet metal. They sit nearly flush with the sheet metal beyond a slight indentation, which is less noticeable after powdercoat is applied. Flush Heads can also be buffed down to make them even less noticeable, and are the faster, more cost effective option. Concealed-head fasteners are not inserted through the metal and are instead mechanically pressed into a CNC milled/machined pocket. Because concealed head fasteners use the CNC mill, they are more expensive than flush heads. They are completely undetectable on the exterior of the metal because concealed head aren’t passed through.
