A split nut compression fastener system includes a pair of half nuts having a beveled end and opposed flats; a nut housing having a cavity, the cavity including an end wall with an aperture and a tapered interior portion to engage the beveled end, and opposing internal flats to engage the half nut flats; a resilient member to urge the beveled ends against the tapered portion; and retaining element. The half nuts may include tapered thread edges to accommodate damaged male threads, or cutting thread edges to repair damaged mail threads. The system may include a pair of stacked nut assemblies with an interlineal compression member disposed between them. The system may include a nut assembly in combination with a vertical hold down. The system includes multiple sets of half nuts for different thread sizes which may be interchanged within a common nut housing. The system may include each half nut having a plurality of thread portions, each thread portion having a thread cutting edge. The system may include each half nut including a second end wall displaced inwardly from the first end wall to form a projecting shoulder, a third flat, and a corresponding recess in the projecting inferior flat to engage the projecting shoulder. |
