It is through the aperture 10 that a threaded shaft would extend when the washer assembly is in use.
  • An inner 2 and outer periphery 3 of the washer assembly is also provided.
  • the nature of the interlocking arrangement between the two c-shaped members may be any mechanical arrangement that still provides the profiled surface 12 while ensuring that when the members are interlocked there is no movement in any direction between the members that breaks the profiled surface 12 of the washer assembly when the washer assembly is being used with a threaded fastener.
  • the c-shaped washers 7 and 8 can be assembled about a threaded shaft and that the split nut fastening members shown in Figure 4 (described below) can be applied about a threaded shaft to form a threaded fastening assembly without any need to pass over an end of the threaded shaft. This arrangement is particularly useful where an end of the threaded shaft is not available or where it is more efficient to bypass the use of an annular washer or non-split fastening member.
  • the washer 1 is annular in shape; and as shown in Figures 2 and 3 the washer assembly can comprise 2 interlocking c-shaped members.

  • a cross sectional view of the profiled surface of either embodiment of washer of the invention is shown in Figure 4.
  • the surfaces 6 and 12 may be inclined or ramped from between about 20 degrees to about 45 degrees, preferably about 45 degrees relative to the axis of the aperture.
  • a threaded fastening member is shown as a split nut 13 having a first internally threaded member 14 and a second internally threaded member 15.
  • Figure 5 shows the cross sectional view of split nut members 14 and 15 nestled on a washer of the invention.
  • the cross section of either of washer embodiments 1 and 7 are equivalent.
  • the profiled surface 6 or 12 of the washers 1 or 7 of each embodiment is dimensioned and shaped such that the washer nestles split nut members 14 and 15.

  • the nut or kit assembly will be manufactured by an injection molding process, where a proprietary plastic granule is dried, heated and then injected into a hot mold forming the shape of the nut.
  • the plastics material will need to have a high resistance to heat and be able to withstand temperatures of greater than 150 degrees Celcius as well as having a high structural integrity and a high resistance to creeping or deforming under load.
  • suitable plastics include Polyamide 6/6 and Vitrex PEEK.
  • the plastics may be optionally reinforced with glass or carbon reinforcing depending on the application to which the fastener is to be put. It is to be appreciated that similar plastics would also be applicable where they provide flexibility and that the corresponding washer or washer assembly could also be injection moulded. It is also to be appreciated that suitable metals and alloys, such as aluminium or steel and the like may also be employed depending on the application to which the fastener is to be put.
  • fastening assemblies can be assembled or disassembled from a threaded shaft easily and efficiently. Where one portion of the threaded member is cross threaded or damaged, the fastening assembly can be assembled remote from the damaged threaded portion and secured without having to try and rethread or force a conventional nut over the damaged threaded portion.
