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).

A motor adapter assembly can couple a motor shaft for a ceiling fan motor to a downrod. The motor adapter assembly can include a base plate, a cradle with arms extending through the base plate, and a threaded bushing secured between the arms of the cradle. Threading a cap to the threaded bushing can be used to pivot the downrod between an upright position and a pivoted position.

A penetrated floating nut includes: a first retaining member including a cylindrical first cylindrical section and a first flange section provided at one end portion of the first cylindrical section; a second retaining member including a cylindrical second cylindrical section and a second flange section provided at one end portion of the second cylindrical section, the second cylindrical section being joined to the first cylindrical section of the first retaining member; and a nut housed in the first cylindrical section of the first retaining member with a gap therebetween and including a third flange section at one end portion of the nut and further including rotation stopping means between the nut and the first cylindrical section of the first retaining member, the third flange section being housed in the second cylindrical section of the second retaining member with a gap therebetween and being capable of contacting an end surface of the first cylindrical section of the first retaining member. A bolt fastened to the nut is capable of penetrating through the penetrated floating nut from the first retaining member side to the second retaining member side.

A retainer comprises first and second legs extending away from a base wall. In one embodiment, the first leg includes a dimple array surrounding an aperture and projecting from an inboard surface of the first leg. In another embodiment, the first leg has a necked portion having a set of first shoulders extending away from a first base, and a first apertured portion extending away from the set of first shoulders. The second leg has a necked and stepped portion having a step extending away from a second base, and a shouldered portion extending away from the step and having a set of second shoulders extending laterally outwardly, and a second apertured portion extending away from the second shoulders. The retainer of either embodiment may be coupled to a nut to produce a retainer and nut assembly.

A method of securing a structure against a slide-type mounting rail of an electronic equipment enclosure includes: providing a hardware assembly having a spring retainer and bolt, a head of which is received at least partially within the spring retainer; positioning the hardware assembly within a T-slot channel of the slide-type mounting rail such that bent edges of deflectable spring arms engage ledges of the T-slot channel to prevent the retainer from rotation; configuring the bolt from an unlocked position to a locked position by rotating the bolt a quarter turn relative to the retainer to position the head transversely within the channel, thereby obstructing the hardware assembly from inadvertent removal from the slide-type mounting rail; placing the structure against the slide-type mounting rail such that a shaft extends through an aperture; and tightening a nut onto the shaft such that the nut is pressed firmly against the structure.

A fastener for retaining a bolt in a hole in a structure, comprising a bushing integrally formed with and extending from the bottom surface of a retainer, the bushing being dimensioned for insertion into the hole in the structure and having a wall thickness ranging from about 0.005 inches to about 0.030 inches, wherein the bushing is configured to be expanded within the hole, thereby securely coupling the expanded bushing within the hole of the structure and anchoring the retainer to the surface of the structure surrounding the hole. A tool for installing a fastener, comprising a tapered mandrel configured for insertion within a fastener situated within a hole of the structure, a drive mechanism configured to retract the mandrel through the fastener and thereby expand the fastener, and a force sensor configured for measuring a force applied by the drive mechanism to retract the mandrel through the fastener.

A CAGED NUT, of the type formed by the composition of a container housing and a nut accommodated therein, wherein said nut is formed by a planar base from which emerges a threaded cylinder linked to said base by means of a connection vault; said housing or cage being formed by a stamped clip that clasps said nut between flexed lateral arms and folds at the ends of said clip; tabs for engaging with the panel where said assembly is to be fastened emerging from said end folds.

Expandable collet bodies with sectional finger-based anti-rotation features are disclosed. The collet body comprises not only a plurality of gripping finger as a first part of a two-part anti-rotation means (ARM), but also a first part of a two part translation arresting means (TAM), which may or may not be sectional in nature. The TAM prevents over translation of a collet body within the work piece(s), and cooperates with a second part of the TAM associated with a work piece or an auxiliary structure. In this manner, a collet body inserted into a work piece or auxiliary structure will not accidentally be pushed beyond the blind side of the work piece(s) during insertion or initial clamp-up.

Fitting for fixing a threaded element to a wall section, including a base body which is penetrated by a recess, which recess is extended along a central axis, further including a clamping ring which is rotatably mounted on an outer surface of the base body, wherein a cam is assigned to the outer surface of the base body or to the clamping ring, which cam effectuates a change in diameter of the clamping ring during a rotary movement of the clamping ring relative to the base body, wherein a coupling part is movably received in the recess and forms with the base body a rotary coupling, wherein a threaded portion of the coupling part determines a thread axis, wherein the coupling part is accommodated in the recess with a variable orientation of the thread axis within a predetermined angular interval and/or within a predetermined distance interval to the central axis.

WELDED BOARD AND ELECTRICAL CABINET STRUCTURE presents a cabinet built with welded frames that use vertical and horizontal profiles, having an internal fastening wall with holes and cutouts to the fitting of a cage nut and an internal fastening tab, a side sealing surface, a front sealing surface and the isolation barrier, the structure being assembled with at least two welded frames, which are assembled in parallel and joined through four depth profiles, said depth profiles being joined directly to the welded frames vertices.
