摘要：
A polymer-coated metal fastener is provided which has both improved ease of drive into a substrate, and improved resistance to withdrawal from the substrate. The coated fastener is prepared by heating a metal fastener, or a portion of it, to about 400-2000° F. and cooling in an aqueous medium containing an acrylic or modified acrylic polymer. The rapid cooling causes formation of a thin yet durable polymer coating on the fastener.
