Zusammenfassung:	A member having a shank is selectively coated with a material such as a metal by loosely sliding a washer made of a material such as a thermoplastic or thermosetting polymer onto the shank, securing the washer such that the washer is in intimate contact with the shank, and immersing at least a portion of the member into at least one coating bath so that a portion of the member is coated and the portion of the shank in contact with the washer is not coated. The member can be an input/output pin for an electronic device and the coating can be applied by methods such as electroless plating or electrolytic plating.
