Various embodiments provide a post-to-beam fastener including a head, a tip, and a threaded shank connected to the head at a first end and the tip and a second end. In various embodiments, threaded shank includes a longitudinal axis extending from the head to the tip, and the tip includes a recess operable to removably receive a drill bit to the fastener.

Disclosed is a sheet-metal fastener configured to join two components, such as sheet-metal. The sheet-metal fastener comprising a head and a shank. The head may define an undercut region and a serrated region. The serrated region can be positioned at an outer perimeter of the head. The serrated region can be composed of a plurality of knurls. The shank extends perpendicularly from the undercut region and comprises one or more threads.

Seal arrangement (48) comprising a plug member (46) configured to seal a through opening (12) in a wall (10); a pressing section (74); and a cover member (70) configured to be connected to the plug member (46) and configured to force the pressing section (74) to press a sealing element (72), arranged laterally outside the plug member (46), towards the wall (10). A kit of parts and a method for sealing a through opening (12) in a wall (10) and for painting the wall (10) are also provided.

Toolbar systems that can be used to mount tools and other items onto vehicles and other structures are disclosed. The toolbar systems may be installed on the underside of a truck cover in order to protect tools or other items during transport, and to allow easy access during use. The toolbar systems are adjustable to many different configurations in order to accommodate various types and sizes of tools and other articles. The toolbar systems are also usable with various types of clamping mechanisms that can releasably secure the tools and other items to the toolbar bases.

In one embodiment, a fastener includes a flexible head and a shank coupled to the flexible head. The flexible head includes a center head portion and a plurality of wing portions coupled to the center head portion. Each of the plurality of wing portions includes a contact area configured to contact a first surface of a part to be fastened. The shank includes a clip groove configured to hold a retainer clip against a second surface of the part to be fastened. The second first surface of the part to be fastened is opposite the first surface of the part to be fastened.

An installation tool assembly kit for a toilet, comprising an installation wrench and an installation nut, wherein the wrench is configured to be removably coupled to the nut via an upper aperture of the nut, the nut is configured to be threadingly coupled to a flange bolt via a lower aperture of the nut, and the nut upper aperture and nut lower aperture are concentrically aligned. The toilet may be a concealed trap, skirted toilet and/or a pressure-assist toilet.

This invention relates to a safety screw assembly and operating key. The head of the screw is movable between a position where it is rotationally integral with the body and a position where it is freely rotatable. The head of the screw has on one face, an opening or a relief, that matches a relief or an imprint formed on part of the operating key. One end of the body of the screw has a stator and a rotor. The head of the screw forms a housing for receiving the rotor, and the assembly forms a translationally movable securing component which is movable between a loose position, where the head is freely rotatable and the rotor and the stator are rotationally integral, and a locked position, where the head and the stator are rotationally integral, where the key has at least one component for setting the rotor into rotation.
