ABSTRACT:
A compositely plated, threaded fastener has zinc plating applied to a threaded fastener core and an aluminum plating is applied to the zinc underplating. Optionally, a polymeric top coat can be applied to the aluminum plating for pigmented appearance. The combination of the composite aluminum and zinc platings not only provide the fasteners with improved corrosion resistance but also provide particularly reduced torque load in driving such fasteners, for example, in drilling applications.
