Abstract

A rigid, all-metal locking nut device having a one-piece, generally truncated cone-shaped crown extending partially from the unsupported end of the nut body to the bearing end thereof, a threaded bore, and a plurality of internal grooves arranged essentially symmetrically formed in the crown and extending from the non-bearing end of the nut body in a direction that has a component parallel to the bore axis, the depth of the grooves at said end being does not rest greater than the depth of the thread for the screw, a part of the crown being next to each groove on the side of the same that goes ahead when the nut is threaded deviated inwards to create a plurality of locking tabs threaded and curved, the shape of the tabs and the elasticity of the nut crown being such that the tabs give way and allow the nut to be threaded on a Male threaded member cooperating but strongly resisting any tendency for the nut to accidentally unscrew under the influence of shock vibrations or the like, while allowing repeated use of the nut after it has been unscrewed from the member.
