ABSTRACT:
A split nut to enable complete separation of the longitudinal halves from a threaded shank so that they may be re-fitted to any other portion thereof, particularly long threaded shanks, without the necessity of turning the nut in threaded relationship to such selected position. It is particularly useful in the case of rusted threaded shanks involving great difficulty in screw-threading the nut on the rusted threads. A special feature of the present construction of the nut halves is that it enables the making of identical and interchangeable halves, which greatly reduces manufacturing and inventory costs.
