The present disclosure provides an insert of a fastening system. The insert includes (a) a flange, (b) a sidewall extending from the flange and defining a first through-hole, (c) a nut including a first end and a second end and defining a second through-hole, wherein the second end of the nut comprises two or more gripping fingers extending longitudinally from the first end of the nut and separated by two or more slots, and wherein the two or more gripping fingers are flexible in a radial direction and biased to converge inward such that the second through-hole is tapered from the first end of the nut to the second end of the nut, and (d) a stopper coupled to an interior surface of the sidewall and positioned between the first end of the nut and the flange.

A screw fastening structure includes: a screw fastener having a threaded portion; and a fastening assist member having a flanged screw hole, a through-hole through which the threaded portion of the screw fastener passes, and a folded part folded back such that the screw hole and the through-hole face each other. A flange of the screw hole projects toward a side opposite to a side of the through-hole, and the threaded portion of the screw fastener is fastened to the screw hole after passing through the through-hole.

Provided is a universal accessory surface mount that allows a broad range of accessories to be attached to the ceilings, walls, and/or flat surfaces of vehicles or campers, or surfaces. The surface mount may have a flange having two sides. The flange may comprise a central insert that is open and recessed on one of the two sides and closed on the other of the two sides. The central insert may be threaded internally and configured to be threaded by a screw.

A thimble assembly for a cyclone separator comprising a plurality of mounting brackets separately mountable on a shelf of the separator along the perimeter of an exhaust opening, a plurality of segments vertically successively suspended from the brackets, the segments of an upper row being joined to the brackets, the segments of each successive lower row being joined to the segments of a row immediately above, each bracket exclusively serving a chord of an arc concentric with the preferably circular opening that is substantially the same in length as the chord of an arc that a segment spans, a center-to-center chordal spacing of adjacent brackets being the same as a center-to-center distance of an adjacent pair of segments.

A disclosed tolerance compensator system reduces or avoids bending of components when the components are fastened to each other, thereby increasing the reliability of the components. The limited number of parts of the tolerance compensator system simplifies manufacturing and reduces costs. A disclosed method for fastening components together using the tolerance compensator system reduces or avoids bending of components, increases the reliability of the components, reduces fastening times, and simplifies fastening procedures.

A flange assembly includes a flange for connection to a hose or pipe, the flange defining a contact face for engagement with a contact face of an opposed flange. The flange assembly also includes at least three clamps spaced circumferentially around the contact face. Each clamp includes a clamp body pivotably secured to the flange and a clamp member mounted on the clamp body, which is movable between a first, retracted position and a second, clamping position. A clamp face of the clamp member faces the contact face of the flange. The clamp member is movable relative to the clamp body to adjust the position of the clamp face relative to the contact face of the flange and adjust a clamping force created between the clamp face and the contact face of the flange to retain an opposing flange in face-to-face engagement with the contact face of the flange.

The presently disclosed fitting stop turn device includes a fitting retainer plate and a backer plate that provide a clamping mechanism to a fitting that passes through a partition such that the fitting retainer plate and backing plate prevent axial rotation of the fitting positioned through the partition. The fitting retainer plate secures the fitting on a first side of the partition and abuts a first side of the partition, while the backer plate abuts a second side of the partition. The retainer plate and backer plate are held in their respective positions against the partition by one or more fasteners that traverse the retainer plate, the partition, and the backer plate.

Provided is a universal accessory surface mount that allows a broad range of accessories to be attached to the ceilings, walls, and/or flat surfaces of vehicles or campers, or surfaces. The surface mount may have a flange having two sides. The flange may comprise a central insert that is open and recessed on one of the two sides and closed on the other of the two sides. The central insert may be threaded internally and configured to be threaded by a screw.

A device mounting structure for mounting a load maintaining mechanism on a hydraulic cylinder, a pipe for suppling and discharging working oil to and from the hydraulic cylinder being connected to the load maintaining mechanism such that the working oil is led thereto, includes a single coupling portion that includes a screw hole and is provided on the hydraulic cylinder, and a bracket to which the load maintaining mechanism is fixed, the bracket being coupled to the coupling portion via a first screw member that is screwed into the screw hole, wherein the bracket includes a first through hole through which the first screw member is passed so as to leave a gap in a radial direction.

An electrical machine (12) comprising a fastening flange (10), wherein the fastening flange (10) has a rim (46), so that the fastening flange (10) is arranged on a housing part (14) of the electrical machine (12) in such a way that the fastening flange (10) surrounds the housing part (14) at least in sections in the circumferential direction (16) of the housing part (14) at least by way of the rim (46), wherein the fastening flange (10) has at least one radially directed raised portion (18) which is integrally formed from the fastening flange (10) and bears against the housing part (14), wherein at least one recess (47) is formed within the rim (46), wherein the recess (47) influences the rigidity of the fastening flange (10).
