    摘要: A threaded fastener including a nut and a bolt with the nut including a ring section and a nut section with the nut section having a main body portion and a neck portion with the neck portion adapted to be moved into the ring section and to be moved radially inwardly such that the threads in the neck portion are moved into compressive engagement with the engaged threads of the bolt to provide prevailing torque structure resisting loosening of the nut member from the bolt.

    摘要: An installation system for securing workpieces of composite type materials and including a fastener adapted to be located in aligned bores in such workpieces with a preselected interference fit, with the fastener comprising a pin having an elongated shank, an enlarged head and enlarged diameter smooth shank section adjacent the pin head, and further having a threaded section extending from the smooth shank section to a breakneck groove located in the shank to define a frangible portion at its free end, the breakneck groove adapted to fracture at a preselected axial load of generally low magnitude, a thin gauged expansion sleeve having an inside diameter less than the diameter of the smooth shank section, the sleeve having an outside diameter permitting the assembly of the sleeve into the workpiece bores with a snug fit, the breakneck groove having an axial strength at least equal to the maximum axial load required to pull the pin member fully into the sleeve with the smooth pin shank section expanding the sleeve into the workpiece bores to provide the preselected interference fit, the breakneck groove having an axial strength no greater than a preselected low percentage greater than the axial load whereby the frangible portion of the shank can be severed at a minimal axial load applying a member to the frangible portion to pull the pin member into the sleeve and then severing the frangible portion separately from the final installation of the fastener.
