A fastener for attaching grooved decking planks to a support member has a body defining an attachment opening spacing apart opposing legs extending from a shoulder. The legs have at least one frontward extending prong. The rear end of the body includes a bend transitioning to a lip. The front end may have downward extending teeth. A nose may extend from the front end while a tail may extend from the rear end of the body. Adjacent fasteners may be joined by their respective noses and tails to form a collated series of fasteners.

One aspect of the present disclosure is directed to a crush washer for a firearm that comprises a ring of material about a center axis having an inner surface towards the center axis and an outer surface away from the center axis, and at least one groove in the inner surface or outer surface. The groove forms: a first flange having an inner surface and an outer surface with a thickness therebetween; a second flange having an inner surface and an outer surface with a thickness therebetween; and a bridge connecting the first flange and the second flange, the bridge having an inner surface and an outer surface with a thickness therebetween. In an undeformed state, the inner surface of the first flange is adjacent to, but spaced apart from, the inner surface of the second flange. In a deformed state, the inner surface of the first flange is closer to the inner surface of the second flange compared to the undeformed state. The thickness of the bridge is less than the thickness of the first flange and less than the thickness of the second flange.

A washer includes a first lobe comprising a first hole, a second lobe comprising a second hole, a third lobe comprising a third hole, and a fourth lobe comprising a fourth hole. A first leg extends from the first lobe to the second lobe, and a second leg extends between the third lobe and the fourth lobe, wherein the second leg is parallel to the first leg. A third leg extends from the first lobe to the third lobe and spaces the first leg from the second leg such that the second lobe is disposed opposite the fourth lobe.

A ceramic fastener assembly for high temperatures. One embodiment is a fastener assembly that includes a ceramic fastener configured to engage a hole of a structure. The ceramic fastener includes a head and a non-threaded shank including one or more indentations around its perimeter. The fastener assembly also includes a sleeve configured to slide over the non-threaded shank of the ceramic fastener. The sleeve includes a hollow cylindrical body, an exterior surface with threads, and an interior surface with one or more protrusions configured to mate with the one or more indentations of the non-threaded shank. The fastener assembly further includes a nut configured to engage the threads of the sleeve to tighten the one or more protrusions with the one or more indentations of the non-threaded shank. The fastener assembly also includes a thermal spacer configured to thermally isolate the nut and the sleeve from the structure.

A fastener assembly is provided. The fastener assembly includes a nut having an internally threaded portion and an annulus extending from the nut and configured for receiving the shank of an elongate fastener. A compression collar is configured for deflecting the annulus into at least one of fixed engagement with the shank or to impart a spring bias of the annulus against the compression collar upon tightening of the nut about a working surface.

An offset hygienic anchor sealing bracket for installation of block style tube and pipe hangers to a paneled strata in which there is no access to the reverse side, there being a need to secure the anchor bracket to an anchor bolt or toggle bolt and simultaneously shield the exposed toggle bolt structure from the environment of the clean room, sterile room, or sanitary room in order to protect the irregular surface of the toggle bolt from caustic cleaning solutions and to prevent the build up of dirt and bacteria, the anchor bracket having bored pedestals in communication with the cavity which encapsulates the exposed portion of the toggle bolt and secures the anchor bracket thereto, the anchor bracket having a plurality of female threaded receptacles for receipt of fasteners utilized in assembling block style tube and pipe hangers, thus securing the block style tube and pipe hanger to the panel at a desired slope and center line.

A connector assembly includes a generally L-shaped fitting with a first mounting portion having a mounting hole(s), a second mounting portion extending generally angled to the first mounting portion and having a mounting hole(s) and a joint portion integrally connecting the two mounting portions. The joint portion has a load section(s) defined between a concave surface section extending between inner surfaces of the first and second mounting portions and a convex surface section extending between outer surfaces of the first and second mounting portions, the load section concave surface section having a radius of curvature. A washer has an outer perimeter surface with a section having a partially spherical profile and is sized such that the spherical surface section is disposed against the joint load section concave surface so that the washer exerts force generally against the joint load section when the washer is clamped to the second mounting portion.
