ABSTRACT:
A fastening tool inserts a self-penetrating fastener into workpieces and then sets the fastener in a manner similar to a blind riveting tool. The fastener has a stem, a mandrel connected to the stem, and a body surrounding a portion of the stem adjacent the mandrel. The body has an enlarged head at the end opposite the mandrel. The mandrel has a point for penetrating the workpieces. The fastening tool applies a force to the fastener, causing it to penetrate the workpiece. The fastening tool then pulls the stem in a direction away from the workpiece while restraining the body against movement relative to the workpiece. The mandrel expands the lower portion of the body radially as it is pulled into contact with the body, forming a second or blind head on the side of the workpiece opposite the fastening tool.
