Abstract

Abstract A fastener including a sleeve having a first flange at one end which extends radially outwardly and terminates in a portion extending longitudinally toward the opposite end of the sleeve for a limited distance, the opposite end of the sleeve being of reduced wall thickness and being adapted to be bent outwardly to form a second flange cooperating with the first flange in holding the sleeve to the workpiece when the sleeve has been inserted through an opening in the workpiece, a nut being received within the sleeve with clearance around its periphery, the nut having outwardly projecting tabs extending through slots in the sleeve into the space provided by the first flange, so that the nut is permitted limited lateral floating movement and precluded from substantial rotation, the bolt having a threaded shank with a pointed end for facilitating entry into the nut, and having a wide thin head provided with a central protrusion engaged by a tubular portion of the driving tool for aligning the driving tool with the head. The tubular portion of the driving tool is spring biased outwardly and is moved inwardly upon engagement with the head at the central portion thereof, while blades on the driving blade tool enter the slot in the bolt head.
