A nut for use with a self-threading bolt-like fastener possessing a cavity for collecting and compacting cuttings produced by the self-threading process. The central bore of the nut is partially threaded, the threads originating at the first end of the nut and terminating between the first end and the second end, the threads having the same pitch as the self-threading fastener it is intended for use with. The self-threading bolt-like fastener has a larger diameter across the cutting threads that the diameter of the central bore of the nut. |
