A bushing includes an upper collar with a lower sheath and an annular shoulder intermediate the collar and sheath. The collar has a plurality of spaced apart notches and the sheath has a plurality of spaced apart slits that may be circumferentially aligned with the notches. The sheath has a plurality of spaced apart ribs projecting outward circumferentially offset from the slit for assisting in maintaining the sheath within a hole in a fastener with the annular shoulder against the fastener. A securing member with an elongate shank extending from a head with a distal portion is maintained in the longitudinal opening in an upright position aligned with the hole. As the fastener is driven longitudinally through the opening and hole, force from the fastener causes the bushing to break away and yields direct contact between the securing member head against the top surface of the fastener.

A stop washer for an elastomeric bearing is manufactured as a single unit from a sheet metal blank and furnished with a surface protection. In addition to its function as a path limiter, it has at least one of the following functions by a structure integrated into the forming process of the sheet metal blank, namely the function of a thread and/or anti-rotation protection. Furthermore, an elastomeric bearing with such a stop washer and a subframe equipped therewith are conceivable.

It is known to use screws to fasten cladding to the structural timber framing of a building. A problem is that in an earthquake event, movement of the wall can cause the screws to bend and cause non-recoverable damage to the cladding and framing. This may adversely affect the ability of a building to absorb energy sufficient to resist the destructive forces that earthquakes bring to bear. The fasteners address this problem. The fastener has a head 2, a first shaft portion (a fuse) 4 and a second shaft portion (a shank) 5. The fuse extends between the head and the shank and has less resistance to bending than the shank.

A clamp assembly that may be used for securing to a raised portion of a surface. The clamp assembly comprising a mounting body of a general block shape having a slot for receiving the raised portion formed in a bottom surface of the mounting body attaching the clamp assembly thereto. The clamp assembly is configured with one or more pins that may be formed in a substantially elongated cylindrical shape. The pins may be configured to be received in one or more push-pin holes formed in the mounting body, whereby the push-pin holes extend to the slot from a side surface of push-pin holes. The clamp assembly includes a fastening element adapted to be received in a fastener hole formed adjacent the push-pin holes in the side surface of the mounting body. The fastening element is configured to secure, attach and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

A versatile clamp assembly that may be used for securing a device generally to an edge of a structure such as a raised portion of a standing seam of a metal roof. The assembly comprises a mounting body with an open loop having a slot for receiving the raised portion formed by the mounting body attaching the clamp assembly thereto. The assembly is configured with one or more pins that may be configured to be received in one or more push-pin openings formed in the mounting body, whereby the push-pin openings extend from a fastener base portion to a second arm portion. The assembly includes a fastener adapted to be received in a fastener opening formed adjacent the push-pin openings. The fastener is configured to secure and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

A connection system for a hot gas-conducting annular duct of a turbine intermediate casing of a gas turbine includes a first housing element, a second housing element situated next to the first housing element in the circumferential direction, and a fastening unit configured for connecting the first housing element and the second housing element to one another at edges adjacent to one another in the circumferential direction, the fastening unit including a clamping element which is mounted on the one housing element with the aid of a connection, the clamping element resting on a clamping surface provided on the other housing element in such a way that the other housing element is accommodated between the clamping element and the one housing element. It is provided that the top side of the clamping surface facing the clamping element has a clamping surface contour—relative to a longitudinal section which extends along, in particular essentially in parallel to the adjacent edges of the two housing elements—which is designed in such a way that it thwarts a rotation of the clamping element about an axis of the connection.

A hanger for a pipe, the hanger comprising: a suspension member configured to engage the pipe, the suspension member comprising a side edge and defining a hole in through the suspension member; a threaded rod extending through the hole; a nut threaded on the threaded rod; and a lock tab washer disposed on the threaded rod between the suspension member and the nut, the lock tab washer comprising a first tab and a second tab, the first tab bent over a side edge of the suspension member, the first tab configured to prevent the lock tab washer from rotating with respect to the suspension member, the second tab bent over a circumferential side of the nut, the second tab configured to prevent the nut from rotating with respect to the lock tab washer.

A fastening unit for connecting a heat-generating body to a heat sink is provided. The fastening unit includes a retaining pin and a retaining element wherein the retaining pin is connected to a retaining head. The retaining pin extends through the retaining element and the retaining head contacts the retaining element. The retaining element is engageable upon a body of the heat sink so as to retain same in a fastening direction of the retaining pin. The retaining element is engageable laterally on the body of the heat sink, the retaining element having, on a side thereof for facing the body of the heat sink, a retaining groove extending in a longitudinal direction perpendicular to the fastening direction. In an assembled state for the fastening unit, at least one groove surface of the retaining groove of the retaining element contacts the body of the heat sink.

The present invention relates to a quick-fit connection assembly not affected by accidental rotations during the installation due to the presence of an innovative connecting element (1) which has, in the threaded external region, one or more sliding tracks (3) suitable for engaging with the nosepiece (91) of a corresponding washer (9).

A method of securing a pipe in a hanger includes supporting the pipe with a suspension member; inserting a threaded rod through the suspension member; placing a lock tab washer on the threaded rod; threading a nut on the threaded rod; preventing the lock tab washer from rotating with respect to the suspension member by folding a first tab of the lock tab washer over a side edge of the suspension member; and preventing the nut from rotating with respect to the lock tab washer by folding a second tab of the lock tab washer over a circumferential side of the nut.
