A fastener includes a base member; a first member, on the base member and having a through bore; a second member, on the base member and spaced from the first member to form a receiving portion to receive a panel structure, including an aperture defining an internal surface, the internal surface including at least one stop member protruding radially inwardly, and a nut member, coaxially aligned within and frangibly connected to the internal surface, including at least one block member protruding radially outward from an outer surface of the nut member to stoppingly engage with the at least one stop member. During use, the nut member moves from a first position, where the nut is frangibly connected to the internal surface, to a second position, where the least one block member abuttingly engages with the at last one stop member.

In accordance with one or more embodiments of the invention, nut restrainers and methods of use are presented, particularly as they apply to high-strength bolted connections for steel structures. Nut restrainers may define a cavity that accepts insertion of a nut, and may include deformable or removable centering elements that allow the nut to move laterally to accept a bolt that is inserted non-concentrically with the nut restrainer, and may comprise a mobile central portion and a rigid outer portion; A method of positioning a nut restrainer concentric with a bolt hole accurate to within the radial tolerance of the bolt hole.

A tolerance compensation arrangement for fastening first and second components with automatic or self-acting compensation of tolerances in the spacing between the components. The arrangement includes a base element having first and second metal elements with inner threads. An adjustment unit includes a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the threaded sleeve. The outer thread forms a first thread pairing of a first thread direction with the inner thread of the first metal element. A fastening screw can be screwed into the inner thread of the second metal element via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.

A cage nut including a nut arranged in a cage. The cage has a base which has a round hole from which two opposing side parts ascend, each side part carrying a supporting portion facing outward. The cage and the nut have diametrically opposed projections which are shaped in such a way that, in a determined rotational position, when the nut is arranged in the cage it can be partially inserted axially into a non-round, preferably square opening in a thin wall, if necessary after compressing the side parts, whereupon the screw can be screwed into the nut.

A tolerance compensation fastening apparatus (1) for fastening a first vehicle component (200) to a second vehicle component (300) by way of a bolt (100), the fastening apparatus being set up to compensate for a tolerance within a tolerance compensation range. A fastening system including such a fastening apparatus, as well as to a method for fastening a first vehicle component to a second vehicle component by way of a bolt.

A connecting device, in particular for connecting two components, includes a housing device, having an axial shaft portion delimiting a receiving space, and a radial flange portion having a screw through-passage terminating into the receiving space, wherein a face of the flange portion facing the shaft portion is a connecting wall, and a face of the shaft portion opposite the connecting wall is a fastening wall, wherein the axial shaft portion is adapted to be inserted into a through passage of a first component and a nut device is in particular axially displaceably and rotatably arranged in the receiving space, wherein the nut device can preferably only be inserted laterally into the receiving space.

Disclosed is retainer for a nut. The retainer is positioned within the frame that provides access to a closure. The closure, in turn, is secured by way of a removable cover. The cover is removably secured to the frame by way of a series of bolts and corresponding nuts. The nuts are secured by way of the retainer to allow the bolts to be secured. Each retainer includes upper and lower opening and an internal area. The upper opening is preferably angled such that the nut must be oriented at an angle in order to be inserted into the retainer. The internal area of each retainer includes a ledge with an angled step. The angled step function is rotating the nut to a horizontal orientation after it has been inserted into the retainer. Thereafter, a user can access the nut with a finger through the lower opening. This allows the nut to be rotated and removed via the upper opening. The various features of the present retainer, and the manner in which they interrelate, are described in greater detail hereinafter.

A threaded insert with a replaceable nut element allows a user to replace only the nut element of the threaded insert rather than the entire threaded insert. The threaded insert includes an insertable housing, a replaceable nut, a retaining mechanism, and an attachment mechanism. The insertable housing allows the threaded insert to be engaged within a wall structure and is used to contain the replaceable nut. The replaceable nut allows the threaded insert to be engaged by a fastener such as a screw or bolt. The attachment mechanism allows the replaceable nut to be attached within and detached from the insertable housing. The retaining mechanism further secures the replaceable nut within the insertable housing and also prevents the replaceable nut from rotating within the insertable housing.

In accordance with one or more embodiments of the invention, nut restrainers and methods of use are presented, particularly as they apply to high-strength bolted connections for steel structures. Nut restrainers may define a cavity that accepts insertion of a nut, and may include deformable or removable centering elements that allow the nut to move laterally to accept a bolt that is inserted non-concentrically with the nut restrainer, and may comprise a mobile central portion and a rigid outer portion; A method of positioning a nut restrainer concentric with a bolt hole accurate to within the radial tolerance of the bolt hole.

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.
