    摘要: A method of making a knob (30) and ferrule (50) for a captive screw (10) is disclosed, the knob (30) integrally attached to the screw (10), the ferrule (50) attachable to a panel (60). The method of making the knob (30) includes providing an aluminum alloy base metal for the knob (30), pressing by cold-forming the base material into a generally cylindrical cup-shaped article (32) using at least one pressing operation, the cup having a generally cylindrical side wall (33), removing any base material situated outside of the perimeter of the cup-shaped article (32) and providing a hole in the bottom of the cup (32), coaxial with the hollow cylindrical walls (33) of the cup (32), thereby forming the knob (30).

    摘要: A method of applying a corrosion-resistant coating to a fastener including preheating an area of the fastener to be coated to elevate a temperature of the area and spraying the preheated area of the fastener with a molten or semi-molten metal. In one embodiment, a corrosion-resistant coating applicator includes a support structure, a slotted fastener conveyer supported by the support structure, a feeder configured to feed fasteners to the slotted fastener conveyer, a fastener aligner configured to align head portions of the fasteners, a heater configured to heat head portions of the fasteners as the fasteners being conveyed by the slotted fastener conveyer, and a sprayer configured to apply a corrosion-resistant coating to the heated head portions of the fasteners being conveyed. The present disclosure also provides corrosion-resistant coated fasteners made using the coating methods and/or coating apparatus.
