The mandrel shank is provided with locking means that secure it in the rivet body after setting of the rivet stud, and the predetermined breaking point is located such that the breaking point lies inside the bore of the rivet body after setting of the rivet stud. Located on the mandrel head is a mounting stud that projects from the mandrel head on the side opposite the mandrel shank.

Abstract: The present invention provides a screw/bolt thread profile geometry that is particularly suited to forming a mating nut thread when the screw is inserted in to a plain diameter hole, in the anchor and rotated in a manner by which the thread helix angle will cause the relative axial forward movement, of the screw/bolt, into the anchor. This rotation and relative axial movement will be the prime mover in developing the nut thread that has mating contact with the screw/bolt thread.

Abstract: An interlocking interface retains a screw head in a socket to prevent migration of the screw head out of the socket, or to lock the screw head in the socket. The interlocking interface may retain or lock the screw at various polyaxial angles with respect to the socket. The screw head includes external corrugations. The socket includes an internal corrugated structure which interlocks with the external corrugations of the screw head when the screw is at various polyaxial angles with respect to the socket. A counterbore may be adjacent either or both ends of the socket.

Abstract: A lock nut assembly 10, 10? has a first component 12 provided with a threaded axial through hole 19; and a second component 14 provided with an axial hole 31. The first and second components 12, 14 are detachably coupled together and arranged so that both components are simultaneously engagable with a common tool to effect application of the assembly 10, 10? onto a threaded member 22 by operation of the tool to impart torque to the assembly 10, 10? in a first direction. The first component 12 initially engages the threaded member 22 with the second component 14 following. The first component 12 provides fastening to the threaded member 22 and is torqued as required. The second component 14 acts to lock the first component 12 onto the threaded member 22.

Abstract: The distribution of load stresses on threads engaged with a standard screw or nut is very unequal. Indeed, the first threads in engagement support a large majority of the load. So if the load is too important, the threads give way and the function is not provided any more by the screw or the nut. In the prior art, threads are known whose depth or pitch varies a lot in order to cause a self-clamping. In particular, the invention aims at optimizing the resistance and the fatigue resistance of the screws by distributing the load at the very best on their threads without causing this self-clamping. It was shown that the control of the pitch variation, within a chosen pitch tolerance, makes it possible to control the stress distribution on the threads. It is possible to determine a different variation for each load case encountered.
