| 20090087280 | REUSEABLE LOCK NUT DEVICE - A reusable lock nut device is provided. The reusable lock nut device includes a nut with an axial bore and at least one setscrew bore extending radially through a sidewall and opening into the axial bore. The setscrew bore accepts a setscrew for interfacing with and selectively locking against a threaded fastener, used with the reusable lock nut device. The threads of the threaded fastener define a thread angle between respective pairs of converging lateral thread walls. An end portion of the setscrew is tapered, with a taper angle that corresponds to such thread angle. This configuration enables the end portion of the setscrew to nest wholly within a thread valley defined between walls segments of the respective pairs of converging lateral thread walls. | 04-02-2009 |
| 20100086378 | SYMMETRICALLY STEPPED BORE COUPLER NUT - A coupler nut with multiple bore diameters that are symmetrically stepped in both directions away from the center bore diameter. The bore diameter at the center is the smallest, and each pair of steps away from the center bore increases the bore diameter. This means that the coupler nut has no single, correct vertical orientation. It has no top or bottom, and as such is vertically ambidextrous. | 04-08-2010 |
| 20100129178 | QUICK-ACTING THREADED FASTENER - A threaded fastener includes an outer body defining a cavity and a central axis extending through the cavity, and a plurality of threaded segments positioned substantially within the cavity. The plurality of threaded segments is movable relative to the outer body generally toward and away from the central axis. The threaded fastener also includes a cap positioned at least partially within the cavity to secure the plurality of threaded segments within the cavity. The cap includes a plurality of projections engaging the plurality of threaded segments and the outer body to inhibit relative rotation between the plurality of threaded segments and the outer body. The plurality of projections is formed as a single piece with the cap. The threaded fastener further includes a snap ring removably coupled to the outer body to secure the cap within the cavity. | 05-27-2010 |
| 20100183402 | TAPPING NUT - 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. | 07-22-2010 |

| 20140017035 | DOUBLE-END THREADED BODY AND INTERNALLY-THREADED BODY - A duplex threaded body having a right-handed and left-handed thread on the circumferential surface of a single solid member. A single-nut or double-nut type internally-threaded body demonstrates a locking effect at an intermediate position without substantially loosening by using a combination of a duplex externally-threaded body and one or more internally-threaded bodies. Moreover, a screw structure in which a pair of internally-threaded bodies can only be removed once they are mutually coupled when screwed onto a duplex externally-threaded body, making it possible to impart tamper-proof characteristics and a locking effect. The duplex externally-threaded body has, on the outer circumferential surface, an overlapping region with a clockwise spiral right-handed thread and a counter-clockwise spiral left-handed thread in an overlapping manner. A right-handed internally-threaded body in which a right-handed thread is formed, and a left-handed internally-threaded body in which a left-handed thread is formed, that are screwed onto a duplex externally-threaded body. | 01-16-2014 |

| 20140308092 | FORM-ROLLING DIE STRUCTURE AND FORM-ROLLING METHOD FOR COMPOUND SCREW - [Problem] The present invention aims to provide, without an increase in cost, a directional indication structure for threaded bodies that enables the visual and tactile distinction between left-hand thread and right-hand thread threaded bodies, enables the identification, from the external appearance and the external surface, of which direction a threaded body should be rotated in order to be tightened or loosened, enables mass production and the like, has a good external appearance, and has form properties that do not impinge the properties inherent in the threaded body or the strength, etc. thereof | 10-16-2014 |
| 20150147138 | NUT - A nut includes a thread portion and a pressing portion. The thread portion is formed at an end of the nut. The thread portion includes a threaded inner wall surface for engaging with a screwing shaft of a screwing piece. The pressing portion is extended from the thread portion and formed at the other end of the nut. A wall thickness of the pressing portion is smaller than a wall thickness of the thread portion. An outer wall surface of the pressing portion is aligned with an outer wall surface of the thread portion. | 05-28-2015 |

| 20090016848 | SCREW NUT, METHOD OF PRODUCTION THEREOF AND CORRESPONDING TOOL - A screw nut from a metal material, which comprises a tapped hole and an inner groove which radially extends in relation to the longitudinal axis thereof. An annular collar is formed onto one of the faces of the screw nut and its cross-section is bent in the direction of the axis to such a degree as to delimit, together with a section of the face surrounding the tapped hole as a contact surface, a receiving slot that is directly associated therewith. | 01-15-2009 |
| 20100278615 | METHOD FOR PRIMARY MOLDING OF A MOLDED PART, AND MOLD PART PRODUCED BY PRIMARY MOLDING, IN PARTICULAR NUT - In a method for primary molding of a molded part having an opening and an internal thread formed in the opening, segments of a course of the inner thread arranged in two different sectors of the opening are formed by molding cores projecting into the opening. For release from the mold, the mold cores are withdrawn from the molded part radially with respect to the longitudinal axis of the internal thread. A molded part produced according to the method has an opening and, formed in the opening, an internal thread that has segments of a course of thread located in different sectors of the opening, wherein one core opening is opposite each segment of the internal thread, which opening penetrates the wall of the molded part radially outward. | 11-04-2010 |

| 20100221087 | Preload locking Wire Insert - A preload locking wire insert comprised of a unitary, coiled wire having a particular polygonal cross-section for use in combination with a threaded fastener and a complementary threaded bore in a work piece, wherein the wire insert provides a ramping surface which locks the threads of the fastener into place against the inner threaded wall of the bore in the work piece. A further embodiment provides for the wire insert to be threaded into the bore in either direction, with no regard to orientation, while still retaining the definitive locking aspect. | 09-02-2010 |
| 20100272539 | ANTI-LOOSE LOCK NUT - The invention is an anti-loose lock nut which prevents a screw coupling between a bolt | 10-28-2010 |
| 20110158769 | TANGED SCREW THREAD INSERT WITH IMPROVED REMOVABILITY - A helical-shaped insert to engage a threaded fastener to a receiving member includes a helical coil having a plurality of coil sections having inner and outer surfaces forming a thread shape, and opposing first and second coil end sections. A removable tang extends radially inward from the first coil end section. A continuously curved surface at a finished end of the second coil end section forms a tangent point where the continuously curved surface tangentially meets the second coil end section outer surface. | 06-30-2011 |
