411090000 | Member extending between and engaging flat formed on side of each of a plurality of bolts or nuts (e.g., side lock) | 6 |
20090263206 | Method and Structure for Preventing Screw From Loosening and Method of Manufacturing Male Screw - Prior to engaging a male screw formed on the outer circumference of a second member with a female screw formed on the inner circumference of a hole in a first member, protruding parts which protrude outward in the radial direction and are positioned at one end side of the male screw in the axial direction are formed in a plurality of regions which are separated from each other in the circumferential direction on the outer circumference of the second member on which the male screw is formed. The male screw is then engaged with the female screw from the other end side of the male screw in the axial direction. The torque required to rotate the male screw engaged with the female screw in the loosening direction is set so as to be greater in a state where the protruding parts are interposed between the male screw and the female screw than in a state where the protruding parts are not so interposed. | 10-22-2009 |
20150110573 | LOCKING FASTENER - A locking fastener is provided that may be automatically unlocked and locked by sliding a wrench onto the nut and removing the wrench. The fastener includes a biased arm extending outward from a wrench bearing surface that presses against a pawl. The pawl includes ratchet teeth that engage ratchet teeth of a retainer to lock the fastener. The fastener is unlocked by compressing the arm with a wrench. | 04-23-2015 |
411091000 | And element on opposite face of substructure restricting rotation of a cooperating nut or bolt | 1 |
20150300398 | ROTARY FASTENER - A rotary fastener includes a mounting base member including an inner barrel and an outer barrel fixedly fastened together, a fastening device including a spring-loaded pin member inserted through the mounting base member and a head member affixed to the pin member outside the mounting base member, an operating cap member fixedly mounted with the head member and rotatable relative to the mounting base member between an upper-limit position and a lower-limit position to move the pin member in and out of the bottom side of the mounting base member between a locking position and an unlocking position, and a guide track unit for guiding movement of the operating cap member relative to the mounting base member between the upper-limit position and the lower-limit position upon a rotary motion. | 10-22-2015 |
411092000 | Having plural openings or notches engaging a bolt or nut on two sides | 3 |
20080292425 | Threaded insert for receiving a threaded fastener in a composite panel - A threaded insert for use in a composite and/or honey-comb matrix has a nut member disposed within a plastic housing. The threads of the nut member have a free running thread section and a thread lock section. When a fastener is made up into the nut member, a surface on the nut member engages an opposite-facing surface on the plastic housing, thereby reversing the nut loading from tensile loading to compression loading. A thermoplastic embodiment of the nut member may be fabricated to meet the specifications of aircraft manufacturers required for the SL2334 insert, including thread reusability, tensile loading (pullout load), shear, and interchangeability with the metal component currently in use. | 11-27-2008 |
411095000 | Elastically or plastically deformable part | 2 |
20090317206 | FASTENING DEVICE - A fastening device for a nut comprises a fastening part configured to engage in a screw element, a securing part configured to engage in the nut, and an intermediate part providing a non-positive connection between the fastening part and the securing part, wherein the intermediate part is made of a restorable material and is designed to apply a restoring torque directed at the original state during a rotation of the securing part in relation to the fastening part. | 12-24-2009 |
20160377110 | THREADED INSERT - The invention relates to an insert ( | 12-29-2016 |
