摘要： A friction bolt assembly having a generally tubular bolt defining a cavity longitudinally extending through the bolt and having a split longitudinally extending along the bolt. A rod longitudinally extends through the cavity. An expansion element is mounted on, or integrally formed with, the rod at or toward the rod leading end and protrudes through the bolt leading end. The expansion element has an engagement surface tapering toward the rod trailing end. A drive head is mounted on, or integrally formed with, the rod at or adjacent the rod trailing end. The rod is actuatable by rotation of the drive head to draw the expansion element toward the bolt trailing end such that the engagement surface engages the bolt, radially outwardly deforming the bolt at the leading end. The friction bolt assembly may comprise means for at least substantially preventing rotation of the expansion element relative to the bolt.
