摘要：A first metal member is contacted with a second metal member. A metal fastener is provided including a top radially enlarged portion, a bottom radially enlarged portion and a shank portion intermediate the thicker portions for forming a circumferential groove about the axis and fastener. The fastener is driven through the first member and into the second member, inducing friction between the fastener, the first member and the second member for at least locally melting portions of the first member and the second member to form a flowable material that flows into the circumferential groove of the fastener and solidifies.
