Abstract: The present invention relates to an anti-loosening bolt coupled to a bolt and a spring and, more specifically, to an anti-loosening bolt which can: prevent the bolt from being unintentionally loosened by a rotating object or by continuous long-time or momentary vibration; be fixed on a wall; be combined with a nut; prevent a periodic shaking phenomenon; and be reused.

Abstract: A moldable wire thread insert 1 for reinforcing a screw-in opening of a component has the following characteristics: a cylindrical spiral 20 made of a helically, wound wire 10, the neighboring coils 30 of which are arranged such that a closed cylindrical spiral wall 22, 24 is present, while at least one end of the cylindrical spirals 20 has a fastening flange 40, which extends radially outwards over the cylindrical spiral wall 22, 24 and with which the wire thread insert 1 is anchorable in the component and/or one end of the cylindrical spiral 20 is designed in a planar manner in order to form an even axial front surface of the cylindrical spiral 20.

Abstract: A nut lock includes a nut body, a locking coil, and a cage. The locking coil includes first and second tangs and has an internal diameter that is smaller than the internal diameter of the nut body. The cage is fixed within the nut body and includes a circumferential wall defining first and second stops. The locking coil is located within the cage, and the first and second tangs are positioned proximate the first and second stops of the cage. The first tang engages the first stop when the nut lock is turned in a first direction, and the second tang engages the second stop when the nut lock is turned in a second direction.

Abstract: A locknut includes a body, a locking element, and a cage. The body has a threaded portion and an unthreaded portion. The locking element includes a coil portion having first and second tangs. The locking element is positioned within the cage, and the cage is secured within the unthreaded portion of the body. The cage includes first and second stops, and the first and second tangs of the coil are proximate the stops to be engaged by the stops during rotation of the locknut.

Abstract: A locking fastener includes a fastener body and a locking band. The body includes a tangential slot. The locking band includes a coil portion and first and second tangs extending tangentially from the coil portion. The first tang extends into the slot to limit angular movement of the first tang with respect to the body. When the locking fastener is turned in a loosening direction with sufficient torque, the second tang contacts the fastener body to open the coil portion and to allow removal of the locking fastener.

Abstract: A self-locking threaded fastener that can be driven using conventional driving tools. The threaded fastener includes a fastener body and a locking band. The body includes a) a threaded portion and an unthreaded portion and b) an aperture extending radially from the unthreaded portion. The locking band includes a curved portion within the unthreaded portion of the fastener body and a tang extending into the aperture to limit angular movement of the tang with respect to the body. The curved portion terminates at an end having a range of radial movement with respect to the fastener body. When the threaded fastener is turned in a loosening direction, the locking band inhibit loosening of the threaded fastener.

Abstract: A locking threaded connection (a) providing free relative rotation in a first direction, (b) preventing unintended relative rotation in a second opposite direction, and (c) enabling intended relative rotation in the second direction. The connection includes male and female threaded portions and a helical spring therebetween. The spring is sized and configured to interfit with the male and female threads. The spring enables relative rotation in the first direction, but prevents relative rotation in the second direction. If removability is desired, the spring is provided with an accessible tang, enabling the locking force of the spring to be released.

Abstract: The invention is an anti-loose lock nut which prevents a screw coupling between a bolt 12 and a nut 10 by a coil spring 11 which is mounted in the inner circumferential surface of the nut 10 from loosening, the anti-loose lock nut characterized in that: an extended diameter portion 50 whose inner diameter is wider than the thread 13 of the nut 10 and in the inside of which a spiral groove is not formed, is formed in the inner circumferential surface of the nut 10; an insertion groove 52 into which a bent end portion 51 is fit-coupled is formed in the end of the extended diameter portion 50, in which the end of the coil spring 11 is outwardly bent to form the bent end portion 51; a semicircular curved portion 53 is protrudingly formed in the inner surface of the coil spring 11, and the outer surface of the coil spring 11 is formed of a flat cross-sectional plane; clearance spaces 54 and 55 which are respectively wider by one pitch than a thread pitch P of the bolt 12, are formed in the lengthy width of the ext

Abstract: A quick mount disk brake rotor is configured for use with a splined hub of a bicycle or the like. The rotor includes a splined rotor carrier that slides over the splined hub and a rub area positioned outwardly from the rotor carrier. The rotor carrier also includes slots which are alignable with a receptacle such as a groove on the hub. A retainer clip is biased through the slots in the rotor carrier and into the groove in the hub to axially lock the rotor to the hub. The clip includes a pair of outwardly extending ends that can be squeezed together to drive the clip out of the groove on the hub against the inherent bias of the clip to enable the rotor to be removed from the hub in a quick and simple manner. The result is a biased retaining member is disengageable from the brake rotor carrier so as to move brake rotor carrier from frictional contact with the retained brake hub by tool-free compression of the biased retaining member.
