| 21 | THREAD REPAIR ASSEMBLY AND THREAD REPAIR KIT | US14275655 | 2014-05-12 | US20140334899A1 | 2014-11-13 | Kevin Steffl |
| A thread repair assembly is provided. The thread repair assembly comprises a cutting-nut housing including a first axial end, a second axial end and an internal cutting-nut interface, the first and second axial ends each having an opening. The thread repair assembly further includes a cutting nut at least partially enclosed by the cutting-nut housing and including a plurality of cutting threads configured to engage a threaded element when the assembly is urged in a first axial direction and disengage the threaded element when the thread repair assembly is urged in a second axial direction opposing the first axial direction. | ||||||

| An apparatus and method for repairing stripped female thread holes in workpieces that form a support for a direct screw connection. A female thread connector is formed from a pop rivet modified with a rotation-preventing outer surface or layer, and installed in the stripped hole with its inner end protruding from the inner side of the support and enlarged into a secondary head in conventional fashion. The rotation-preventing outer surface engages the hole so that a self-tapping screw can be threaded through the connector rivet to make a solid, durable, blind screw connection between an outer workpiece and the support. | ||||||
| 23 | METAL SHEET, METHOD FOR FIXING SAID METAL SHEET BY FLOW DRILLING AND ASSEMBLY COMPRISING SAME | US12838543 | 2010-07-19 | US20100275669A1 | 2010-11-04 | Ludovic Vollet; Abdelghani Rayeh; Daniel Dijols |
| The invention concerns a flow drilling and tapping method for assembling thin metal sheets. A tubular extension (12) produced on said metal sheet comprises a conical mount (18) at said metal sheet (10). Through said mount (18), advantageously provided with a hexagonal base (24), the loads are transmitted along the tubular extension (12), and it is possible to fix a perforated element (1) on a metal sheet (10) having a thickness less than 1.5 mm and to apply a standard tightening torque. | ||||||
| 24 | TAPPING NUT | US12355791 | 2009-01-18 | US20100183402A1 | 2010-07-22 | CHING-JU TENG |
| A tapping nut includes a cylindrical tunnel, a conical tunnel, a plurality of slits and a plurality of edges. The diameter of the cylindrical tunnel is marginally smaller than that of a bolt to be tapped by the tapping nut. The conical tunnel extends and expands from the cylindrical tunnel so that the bolt can be introduced into the cylindrical tunnel through the conical tunnel. The cutting edges are formed on an internal side of the tapping nut. Each of the cutting edges extends along a related one of the slits so that the cutting edges can cut the bolt while the slits allows the removing of debris of the bolt. | ||||||

| A conductive male thread (22) has a thrust bearing flank (22a) coated with an insulating paint layer (23), and a conductive female thread (12) has a thrust bearing flank (12a) formed with a conductive projection (13) to break through the paint layer (23) and bite in that flank (22a). | ||||||
| 26 | Nut for turning onto a threaded stud | US10236 | 1993-01-28 | US5326208A | 1994-07-05 | Wolfgang Werner |
| A nut for turning onto a threaded stud and having a smooth bore extending from an inwardly-tapering conical lead-in area, the nut being characterized in that in the lead-in area a stripping zone is formed by a plurality of parallel tubular cavities of smaller diameter than the bore of the nut, in that the cavities are spaced apart and arranged symmetrically about the axis of the bore of the nut, in that the axis of each tubular cavity is spaced from the axis of the bore of the nut by a distance smaller than the sum of the radii of the tubular cavity and of the bore and greater than the radius of the bore, in that the intersections of the walls of each tubular cavity with the wall of the bore of the nut form cutting edges, and in that the respectively adjacent tubular cavities are linked to one another via cavities provided therebetween so that a coating stripped from the threaded stud as the nut is turned onto the stud can be accommodated in this cavity.Preferably, the nut has three tubular cavities which are linked together by three linking cavities. | ||||||
| 27 | Tuning screw having a resilient plastics bush which supports the tuning plunger within a metal bush | US644688 | 1984-08-27 | US4647883A | 1987-03-03 | Robert F. Oxley |
| A microwave tuning device including a cylindrical metal bush having an internal screw thread. A metal rod-like plunger is axially displaceable within the plastics bush. A plastics bush is fitted over one end of the plunger and fixed thereto by means of splines and grooves. The bush is inserted into the internal screw thread so as to form a corresponding mating screw thread on its outer periphery. A plurality of fingers extend from one end of the metal bush and resiliently engage the outer periphery of a plain portion of the plunger so as to provide resistance to unintentional rotation of the plunger in the metal bush and electrical interconnection therebetween. | ||||||
