Disclosed therein are a coupling boss and a method for fabricating a coupling boss, that a collar part is formed through a collar drawing process using a metal plate material, and then, a body part of the coupling boss is firmly combined to a substrate plate through processes of deep drawing, tapping, cleansing, plating and iron coining in order, thereby maximizing competitive power in price, miniaturizing the coupling boss in size, and maximizing tensile strength, compression strength, and surface roughness. In this instance, a more stable material thickness can be kept by performing a collar drawing process or a curling process when a screw part of the coupling boss is formed. The processes of: forming a collar part through a collar drawing process for forming a screw part of the coupling boss using a metal plate material; forming a body part and a flange part on the metal plate material, on which the collar part is formed, through a deep drawing process; and tapping to form the screw part on the inner peripheral portion of the collar part and the processes of: forming a body part and a flange part by a deep drawing process using a metal plate material; forming a collar part on the body part by a curling process; and tapping to form a screw part on the inner peripheral portion of the collar part are performed selectively. After that, the formed coupling boss is firmly combined to a substrate plate through the processes of cleansing, plating, and iron coining.

Sorry for my bad English. Are you able to inform me how am i able to get a blog like yours?
