  • Patent number: 9643237
    Abstract: The compound die includes a working surface with a coarse end for forming coarse threads and a fine end for forming fine threads. The coarse end has coarse crests and coarse roots thereon angled at a coarse thread pitch angle for the screw to be formed. The fine end has fine crests and fine roots formed into a working surface thereof at an angle matching a pitch angle for the fine threads of the screw to be formed. A transition is provided between the coarse end and fine end where each of the coarse roots is aligned with one of the fine roots. A screw such as a bolt is roll formed by first being rolled between a standard die parallel with the compound die and a course end of the compound die, followed by rolling between the standard die and the fine end of the compound die.

  • Patent number: 8790057
    Abstract: A fastener having a shaft, a threaded portion, a positioning member and a rivet head. The shaft has a first diameter and extends from a first end to a second end. The threaded portion is positioned on the shaft. The positioning member is provided on the shaft proximate the second end. The rivet head extends from the second end of the shaft in a direction away from the first end, with the rivet head having a second diameter which is less than the first diameter of the shaft. The rivet head is configured to be deformed such that the deformed rivet head has a third diameter which is greater than the first diameter, thereby securing the fastener to a mating member which is positioned between the positioning member and the deformed rivet head.

  • Patent number: 5181310
    Abstract: A method of making a threaded insert assembly for sheet material wherein a threaded insert that is a single unitary element is installed in a closely fitting hole in the sheet material with its threads occupying the hole. The sheet material around the hole on the exit side of the material is then upset into the threads of the insert in order to hold it by its threads so that it is adjustable by rotation. An unthreaded tip effectively prevents removal of the insert by back-screwing.

  • Patent number: 4642010
    Abstract: A threaded fastener for installation in threaded engagement with an initially unthreaded apertured workpiece and which after installation can be removed in the manner of a screw or bolt, has a shank and an enlarged head. At least part of the shank intermediate between its ends has an external screw thread having a sharp crest, and can be radially expanded to cause the thread to embed in the workpiece. A bore extends through the head and the entire shank or at least the threaded part of the shank for receiving means for expanding the shank. An end portion of the shank remote from the head may be unthreaded to avoid splitting of the shank during expansion.The method of installing the fastener involves pulling a tapered mandrel along the bore to expand the shank. The mandrel may have a key-forming head of non-circular cross-section whereby the bore of the fastener can be adopted to receive a key of non-circular cross-section for turning the fastener in the workpiece.

  • Patent number: 4448392
    Abstract: A thread stop is provided for a screw jack including at least one elongated, substantially cylindrical screw member having an external thread. The thread stop comprises at least one radially outwardly deformed part in a predetermined portion of a minor diameter of said external thread. This formed part is formed by a method including ductilely outwardly deforming a predetermined portion of a minor thread diameter of the external thread, so as to retain the hardness of the deformed portion substantially similar to that of the remainder of the screw member.
