    摘要: A self-drilling dowel is formed by a tubular member defining an axially extending bore. The tubular member has a leading end and a trailing end with a cutting head at the leading end. A spreader member is insertable into the bore for expanding the tubular member. A member, preferably a plate, is positioned within and extends transversely across the bore adjacent the leading end forming a closure. The bore closure member is spaced axially from the leading end and it is separate from the tubular member and is displaceably fitted within the bore.

    摘要: An expansion dowel consists of an axially extending dowel body with a spreading member at its leading end and an expansion member extending around the dowel body rearwardly of the spreading member. A helically arranged control cam surface is formed on the expansion member and faces toward the trailing end of the dowel body. A stop is formed on and extends outwardly from the dowel body and contacts the control cam surface. When the dowel body is turned around its axis relative to the expansion member, the stop rides on the control cam surface and causes the spreading member to expand the expansion member radially outwardly.
