ABSTRACT:
A fastening nut, which by virtue of precisely located laser cuts and the application of predetermined torque to a grip member, is enabled to break into several parts, one of which can be used as a jam nut. The nut is provided with an internally threaded sleeve, a grip member and interconnecting means, the latter of which may be provided with one or more shear areas by virtue of a series of laser cuts. At a predetermined torque on the grip member, the sleeve is sheared from the interconnecting means and grip member and, as a second embodiment, the interconnecting means may be provided with internal fastening threads so that further torquing of the grip member drives such interconnecting means into the sleeve and thereafter a second shear separation is effected to remove the grip member from the jam nut.
