A toner cartridge includes: a housing to accommodate toner and including a fastening boss at a front end; a front cover including a fastening hole aligned with the fastening boss; a fastening member including a fastening portion and a head portion, the fastening portion configured to pass through the fastening hole and be fastened to the fastening boss to couple the front cover to the housing; and a separating portion to allow the fastening hole to be separated from the head portion of the fastening member by an external force acting on the front cover.

A fastener which includes a first portion of a shaft which defines threads, and a second portion of the shaft, which extends from the first portion of the shaft, includes a planar curved surface. A method for securing a fastener to an e-nut, which includes the step of inserting the fastener positioned within an e-nut into an opening defined by and which extends through at least two components to be secured together, wherein: a first portion of the shaft of the fastener defines threads; and a second portion of the shaft of the fastener, which extends from the first portion of the shaft, defines a curved planar surface.

A fastening arrangement with damping effect, consisting of two structurally identical fastening units each having a central first through opening. Each fastening unit comprises a mounting element and a damping element. The mounting element is disc-shaped with a central second through opening and an identical detent structure extends from a first side of each mounting element. The damping element is disc-shaped with a central third through opening and is arranged at last partially in the central second through opening of the mounting element. Due to this construction the two fastening units can be fastened to one another by means of the mutually facing first sides having the identical detent structure of the respective mounting elements with first component arranged between them.

A roof mount assembly mounts a structure to a roof having a rafter and a substrate supported by the rafter. The roof mount assembly includes a piece of flashing positioned on the substrate. The flashing includes a first surface, a second surface opposite the first surface and an aperture extending through the flashing. A fastener extends through the flashing aperture. A bracket is connected to the flashing via the fastener, and the bracket is sized to support at least one roof-mounted structure on the roof. A seal is positioned between the flashing aperture and the fastener. The seal is sized to form a water-tight seal with the aperture to inhibit flow of fluid through the aperture. The seal includes a first portion and a second portion, in which the first portion is positioned to abut the flashing first surface and the second portion is positioned to extend through the aperture.

A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, including, two identically constructed damping elements. Each damping element includes: a head portion with a first outer diameter, a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as a central first thru-opening, and only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection. By means of the only one sleeve, the two identically constructed damping elements with bottom sides, facing each other, of the head portion with the first component arranged in between are fastenable to one another.

A tile-securing system having a polymeric wedge component positioned between two adjacent tiles that are in plane and the polymeric wedge component contacting a side edge of each adjacent tile, wherein the polymeric wedge component exerts a force against both side edges; the polymeric wedge component being secured to a solid substrate using a fastener.

A fixing disc (1) for initially fixing a fastening element (2) in an opening of a component to be fastened, in particular a facade panel, during mounting of the fastening element (2) and for cutting into and/or removing a defined region of a protective film on the component to be fastened during mounting of the fastening element (2) is described. The fixing disc (1) has a fixing means for initially holding the fastening element (2) in a predetermined position relative to the opening during mounting of the fastening element (2), at least one connecting means (4) for at least temporarily producing a connection between the fixing disc (1) and the fastening element (2), and at least one cutting and/or friction means (5) on that side of the fixing disc (1) which faces the component to be fastened. Furthermore, a fastening element (2) corresponding to the fixing disc (1), a system consisting of fixing disc (1) and fastening element (2), and a corresponding method for cutting into and/or removing a protective film are described.

A doubling-up fitting includes an expansion sleeve which has a sleeve base with a sleeve base opening and has at least one expansion tab which can be spread radially outward. An inner ring is axially displaceable in the expansion sleeve towards the sleeve base in a tightening direction in order to spread the at least one expansion tab radially outward. A threaded bolt with a screw thread and with a bolt head engages behind the inner ring in the tightening direction. A threaded part has a widened head and can be screwed to the screw thread of the threaded bolt. The opening diameter of the sleeve base opening and the clear opening diameter of the inner ring are each greater than the bolt diameter of the threaded bolt.

An expansible fixing plug, having a sleeve-like portion, an expander body, and an expansion part which has expansion elements which, in a non-expanded state, are integrally joined to the sleeve-like portion and to the expander body. In addition, the expansion part has connecting elements which integrally join the sleeve-like portion and the expander body in the non-expanded state and also in the expanded state. The connecting elements are interlockingly connected to the expander body.
