An attachment system intended to equip a wall (17), the system including a nut intended to receive a screw (31) of which the orientation is normal to the wall (17), the screw (31) passing through an element such as an outer panel (32) in order to attach the element to the wall (17). The attachment system comprises a socket (26) having a threaded cylindrical outer face (34) intended to be screwed into a hole (29) passing through the wall (17) and having dimensions greater than the dimensions of the fastener that the repair socket (26) replaces, the socket (26) carrying, in the central region of same, a nut (28) receiving the attachment screw (32).

An equipment mounting system for mounting equipment to a support structure is described. An equipment mounting system including: (i) a mounting plate having defined therein a plate aperture of a particular shape; (ii) a bolt having a shaft portion including a threaded portion and a non-threaded portion that is of a complementary shape that complements the particular shape of the plate aperture; and (iii) a washer having defined therein a scored aperture that includes multiple radially extending scorings. In an assembled configuration of the mounting plate, the bolt and the washer, the plate aperture of the particular shape aligns with the scoring aperture such that both of the plate aperture and the scoring aperture receive the non-threaded portion of the complementary shape, and the particular shape of the mounting plate engages with the complementary shape of the bolt to prevent rotational displacement of the bolt around the mounting plate.

Inexperienced users of conventional self-drilling drywall anchors may apply too much torque to its screw drive, even after the anchor has become fully bedded down in the drywall, under the mistaken impression that applying a greater torque will improve security of the anchor within the drywall. However, continuing to rotate the anchor after it has been fully inserted into the dry wall continues to rotate the anchor within the drywall and gouges out drywall material from around the anchor. Such gouging causes a cavity to form around the anchor, reducing its security within the wall. The present invention provides a self-drilling drywall anchor having a screw drive 16 that comprises a clutch configured to limit an amount of torque transmitted to the shank 5 by a tool engaged with the screw drive 16. In this way, a user may drive the anchor into a drywall, but over-tightening is prevented as the clutch limits the amount of torque transmitted to the shank 5, thereby preventing the external threads 7 on the shank from gouging out drywall material adjacent to the anchor and reducing the anchor's security within the drywall.

A fastening system includes an anchoring structure defining a threaded bore. A stud or insert is threaded into the threaded bore. A lockring is fixed to the stud or insert to prevent relative rotation of the stud or insert and lockring. The lockring includes a key extending radially outward from the stud or insert. The key of the lockring is seated in a keyway defined in the anchoring structure to prevent relative rotation of the stud or insert and the anchoring structure. There can be multiple keys extending radially from the lockring and multiple corresponding keyway defined in the anchoring structure, wherein each key is engaged in a corresponding keyway.

A method of assembling a steering column assembly includes pressing a first pivot bushing into a first rake bracket first opening of a first rake bracket and inserting a first pivot fastener into the first pivot bushing and into a first mounting bracket opening of a first mounting bracket arm of a mounting bracket. The method further includes displacing material of the first mounting bracket arm with first splines of the first pivot fastener to form first mating splines within the first mounting bracket opening.

The present disclosure relates to non-cylindrical fastening systems and related methods, such as methods of installing a non-cylindrical fastening system. Presently disclosed non-cylindrical fastening systems may include a first fastening component and a second fastening component, where the second fastening component includes an elongate shank configured to be inserted through a hole in the first fastening component and through a hole in a structure to which the first fastening component is being secured. The holes in the first fastening component and the structure may be non-circular, and the elongate shank may be non-circular in perpendicular cross-section. Disclosed fastening systems may also include a third fastening component configured to be installed onto the elongate shank, and substantially prevent axial movement of the elongate shank with respect to the structure and/or first fastening component. Such fastening systems may lower the number of parts required in manufacturing an apparatus, such as an aircraft.

An aircraft joint between overlapping first and second components includes a fastener assembly. The fastener assembly includes a threaded fastener and a boss having an outer diameter and a threaded internal bore. The boss is fixedly attached to the second component at the overlap region. The first component has a through hole having a diameter sized to receive the outer diameter of the boss. The boss is received in the through hole from a first side of the first component. The fastener extends through the through hole from a second side of the first component opposite the first side. The fastener is threadably received in the internal bore of the boss and reacts against the second side of the first component to fasten the first component to the second component.

The present disclosure relates to a fastener system for use in securing objects, such as stress skinned panels, to a structural support, such as an aircraft spar or cross member. The fastener may be provided with a radially-expandable collar assembly, an anti-rotator assembly, a shaft, and a bolt-lock.

A screw bolt for connecting a lower casing part of a turbine and an upper casing part of a turbine, has a bolt body with a lower end and an upper end, an external thread being arranged on both the lower end and the upper end. A casing for a turbine has a lower casing part, an upper casing part, a screw bolt and two attachment nuts screwed onto ends of the screw bolt, wherein the upper casing part has an upper receiving section and the lower casing part has a lower receiving section of a continuous screw bolt receiving portion for receiving the screw bolt. A turbine has such a casing and a method for assembling such a casing of a turbine.

An assembly includes a mounting component having a first surface and a second surface with a hole extending between the first surface and the second surface. The assembly includes a flange extending generally perpendicularly in a first direction from a first end of the mounting component, and a first tab and a second tab extending generally perpendicularly in a second direction from a second end of the mounting component, wherein the first tab and the second tab are spaced apart from each other. The assembly includes a boss extending from a base plate, a fastener extending through the hole of the mounting component and into the boss, and an anti-rotation projection fixed to the boss and positioned between the first tab and the second tab.
