An improved fastener comprising a fastener body orientated about a central axis and having a tool-engaging portion, a threaded fastening portion and a shroud-receiving portion having an inwardly facing annular groove orientated transverse to the central axis; a shroud concentrically mounted on the shroud-receiving portion to rotate relative to the fastener body under an applied external torque and having an axially-buckled radially-extending annular protrusion extending outwardly transverse to the central axis and disposed in the inwardly facing annular groove of the shroud-receiving portion of the body; the axially-buckled radially-extending annular protrusion of the shroud and the annular groove of the shroud-receiving portion of the body forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis.

An improved fastener comprising a fastener body orientated about a central axis and having a tool-engaging portion, a threaded fastening portion and a shroud-receiving portion; a shroud concentrically mounted in the shroud-receiving portion to rotate relative to the fastener body under an applied external torque and having an outwardly extending annular shoulder; the shroud-receiving portion comprising an inwardly deformed stop radially overlapping the outwardly extending annular shoulder of the shroud; and the deformed stop of the shroud-receiving portion and the annular shoulder of the shroud forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis.

An improved fastener comprising a fastener body having a tool-engaging portion, a threaded fastening portion and a shroud-receiving body portion; a shroud concentrically mounted on the shroud-receiving body portion and having an inner surface facing an outer surface of the shroud-receiving body portion; the inner surface of the shroud comprising an annular groove and the shroud-receiving body portion comprising a substantially arch-shaped axially-buckled radially-extending annular protrusion extending outwardly transverse to the central axis and disposed in the annular groove of the shroud; and the annular protrusion and annular groove of the shroud forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis such that the shroud will rotate relative to the fastener body under an applied external torque prior to the fastener body rotating when the fastener is engaged with an external structure at a design installation torque.

A container for dispensing an aerosol product. The container (1) includes a body (2) formed of plastics material such as PET, and a mounting cup and collar assembly (53). The body (2) includes a neck (10) defining an opening (50) having internal and external walls (51 and 52), respectively. The mounting cup and collar assembly (53) is formed of malleable material, and is shaped to straddle the internal and external walls (51 and 52) of the opening (50), and be crimped to the external wall (52) of the neck (10). The mounting cup and collar assembly (53) is preferably of unitary construction, and, includes a lining (60) on its inner surface to assist in providing a seal between the components.

A riveting tool configured to install a plurality of fasteners simultaneously is provided including a body having a generally central cavity. A strike surface is arranged at a first end of the body and a plurality of contactors extends generally outwards from a second, opposite end of the body. Each contactor includes an engagement surface configured to contact a surface of an adjacent fastener when a force is applied to the strike surface. A biasing mechanism is arranged within the cavity adjacent an upper cavity surface. A dowel is positioned within the cavity adjacent the biasing mechanism. The dowel is configured to engage a portion of an adjacent nut plate and translate within the cavity.

In an example embodiment, the flange 10 has one or more openings 90 for accommodating fasteners 92 for fastening the flange and tubular member (e.g., for fastening the grab bar) to a structure such as a wall, as for example shown in FIG. 6. In example embodiment as shown in FIGS. 6 and 7, flange covers 94 that extend over the flange 10, so as to cover the flange, may be used. The flange cover may be installed over the tubular member prior to the bucking, or from the opposite end of the tubular member after buckling. As can be understood, if flanges are connected to both ends of the tubular member in accordance with the example embodiment herein, the flange covers must be placed over the tubular member at least prior to the bucking of the second end portion of the tubular member. In an example embodiment, each flange cover has an opening 96 having a diameter larger than the outer surface diameter of the tubular member but smaller than the outer surface diameter of the buckled section of the tubular member. A such, the flange cover can be axially retained by the its corresponding buckled section of the tubular member. If the flange cover opening has a diameter greater than the diameter of the buckled section of the tubular member, the cover will be axially retained by the flange. The flange cover should have an appropriate area to cover its corresponding flange. In the example embodiment shown in FIGS. 6 and 7, the flange cover 94 has a radially extending surface 98 from which extends an axially extending surface 100. With this example embodiment, as shown in FIG. 6, the radially extending surface 98 covers the flange 10, while the axially extending surface 100 surrounds the flange 10.

A tubular member and flange combination includes a tubular member having a buckled section proximate an end of the tubular member. A flange is penetrated by an end of the tubular member where an end section of the tubular member is bent over the flange such that the flange is axially retained by the buckled section and the bent end section of the tubular member. A method of forming the tubular member and flange combination includes buckling the tubular member at a location proximate an end of the tubular member forming a buckled section, placing the flange over the tubular member end section such that the tubular member end section penetrates an opening of the flange, and bending an end section of the tubular member to extend over the flange, such that the flange is axially retained by the buckled section and the bent end section of the tubular member.
