20080260491 | Fall-Off Preventing Element and Loosening Preventing Nut - Provided is a fall-off preventing element and a loosening preventing nut, which, by a wire of a coil spring, with a free lower end, being fitted onto a thread groove of a bolt, can prevent fall-off of a nut or loosening of a nut. A fall-off preventing element is screwed onto a bolt and includes a coil spring portion and a cylindrical main body affixing an upper end of the coil spring portion and having an opening formed therein in which a lower end of the coil spring portion is latched. The coil spring portion is made smaller in its inner diameter than the outer diameter of a leg portion of the bolt. The lower end of the coil spring portion is latched in a diameter-expanded state to the cylindrical main body, and the lower end of the coil spring portion is enabled to move in a diameter-expanding direction. | 10-23-2008 |
20090041560 | LOCK NUT - A lock nut includes a nut body in which there is a drill hole equipped with an internal thread for a bolt body equipped with an external thread. In the nut, there are provided essentially axial cuts which extend to the drill hole over part of its length. Locking claws are positioned in the cuts. The locking claws bite when pressed against the bolt to prevent the nut from opening. The cut is of such a shape that a fulcrum is created for the locking claw, with the aid of which the locking claw can be levered away from the bolt. | 02-12-2009 |
20110305538 | Self-Locking Screw Connection - A screw connection having a screw section and a nut threaded thereon. A self-locking effect of the nut on the screw section is achieved in a simple manner in that an intermediate disk is supported non-rotatably on the screw section and is received on the nut so as to be rotatable relative to the nut. The intermediate disk includes a grid distributed around the circumference of the intermediate disk, and the nut carries at least one resiliently elastic, radially displaceable catch formed by a sheet-metal part which, after installing the nut, positively engages the grid to lock the nut against rotation relative to the screw section and intermediate disk. Upon application of a wrench to the nut, the at least one resilient, radially displaceable catch is compressed and drawn out of engagement with the grid, so that the nut can be rotated relative to the screw section. | 12-15-2011 |
411195000 | Other element is a bolt, and member includes opening configured to engage side flat thereon | 1 |
411196000 | And further includes spaced, axially extending legs for engaging side flats on the nut | 1 |

411197000 | Structure is coaxial, distinct member (e.g., washer) that restricts nut piece when fixed | 8 |
20090110510 | WASHER INCLUDING PROTRUSIONS FOR USE IN A FASTENER ASSEMBLY - A washer, including a body having a first face, a second face, and an aperture extending through the body from the first face to the second face, and a plurality of protrusions extending from at least one of the first face and the second face. The plurality of the protrusions have sufficient structural integrity to create a plurality of corresponding deformations in a separate mating surface during compressive loading of the washer against the separate mating surface. | 04-30-2009 |
20110299956 | Locking Plate to be used in a Locking Arrangement and such a Locking Arrangement - The present invention refers to a locking plate ( | 12-08-2011 |
20140178147 | ANTI-THEFT FASTENER WITH LOCKING FEATURE - An anti-theft fastener with locking feature includes a nut, a nut casing, a lock casing and a lock. An engaging ball of the lock casing gets embedded in an engaging groove of the nut casing. The lock and its' casing are positioned inside the nut casing. An abutting portion of the lock no longer abuts against a positioning ball of the nut. The positioning ball is no longer embedded inside a positioning engaging passage of the nut casing, thereby preventing the nut casing from driving the nut except idling. Under locked condition, the fastener is unable to be mounted. To dismount the fastener requires turning the lock with a key until the engaging ball falls into a curved groove of the lock and exits the engaging groove. The positioning ball is pushed outward and embedded inside the positioning engaging passage, thereby unfastening the screw element. | 06-26-2014 |

20100303580 | UNLOCKING-RESISTANT AND LOOSENING-RESISTANT NUT ASSEMBLY - An unlocking-resistant and loosening-resistant nut assembly includes a conic nut and a wedge washer. The conic nut includes a conic portion, a force application portion, and a first wedge face formed on a bottom surface of the conic nut. The force application portion includes a hexagonal prism to enable force application thereto by a socket or open-ended wrench. The conic portion has a curved contour that shows a concave curve. The wedge washer includes a circular washer having a diameter greater than the conic nut. The wedge washer has a surface on which a second wedge face that corresponds in configuration to the first wedge face of the conic nut is circumferentially formed and an opposite surface forming at least one sharp fitting rib that has a cross-section comprising a right-angle having a hypotenuse extending in the direction of tightening the conic nut. | 12-02-2010 |
20140154026 | Slider Locknut - A locknut ( | 06-05-2014 |
20140356098 | NUT LOCK - 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. | 12-04-2014 |
411200000 | Member comprises key movable laterally into engagement with threaded elements | 1 |
20150010372 | RATCHETING FASTENER - The specification discloses a fastener assembly including two elements. One element is an elongated body including that a gear rack and a radial stop. The other element is a nut fitted over the elongated body and including a pawl engaging the gear rack. The current embodiment includes two pairs of gear racks and two pairs of pawls. The two pairs of pawls are axially offset from one another. The elongated body and the nut are keyed to prevent relative rotation therebetween. The elongated body defines a conduit through the fastener assembly. | 01-08-2015 |
411201000 | Member includes plastically deformable portion | 1 |
20100247266 | Self-locking nut - A self-locking nut comprises a slotted nut and a locking nut and is assembled by complementary asymmetrical threading. After the locking nut is threaded onto the neck of the slotted nut, the assembled self-locking nut turns freely as it is threaded onto the shaft of a bolt. Once the forward face of the slotted nut contacts the material being fastened, additional turns clamp the material to the desired torque. Now, when additional torque is applied to the locking nut, its internal thread slides forward along the shallow incline of the asymmetrical external thread on the neck of the slotted nut, thereby exerting a compressive radial force on the slotted neck. | 09-30-2010 |
