Disclosed herein is an integrated bonding mid clamp device for solar panel mounting and grounding, as well as a related system and method. The integrated bonding mid clamp includes a deformable toothed washer for breaking an anodized layer of a solar panel frame. The deformable toothed washer is capable of deforming to avoid obstructing proper contact between the mid clamp and the solar panel frame.

An anchor bolt fastener assembly with specialized connection capabilities and features for attaching building components to concrete slabs, walls, ceilings, and/or structural surfaces. Compression force can be established and maintained over time using a compression washer in combination with a specialized fastener stud that is designed to exploit the compression washer benefits. Methods of using exemplary embodiments include installing the anchor bolt fastener assembly relatively flush with the surface of the concrete slurry by direct insertion in the slurry using a specialized threaded anchor bolt float. Once the slurry hardens, the anchor bolt and anchor bolt float embedded in the concrete slurry cooperate with the specialized fastener stud to secure the building component to the concrete.

A mounting hardware and theft deterrent device includes a hand knob; a threaded screw coupled to the hand knob; a U-clip configured to replace a stock retaining clip on a motorcycle frame and for placement on the motorcycle frame to receive the threaded screw coupled to the hand knob and thereby to secure a motorcycle saddlebag to the motorcycle; and a lock washer for placement over the threaded screw coupled to the hand knob before the threaded screw is inserted into the U-clip. The hand knob, threaded screw fixedly coupled to an underside surface of the hand knob, U-clip, and lock washer collectively form the theft deterrent device. The theft deterrent device is configured for utilization to secure a motorcycle saddlebag to a motorcycle frame without a need for any additional installation tools. The theft deterrent device includes a retaining clip to hold the hand knob to the motorcycle saddlebag.

A fastener with a locking mechanism includes an elongated bolt member with threaded segment defining a banking feature and generally planar surfaces, a nut member, a washer member, and a lock member. The nut member has a threaded bore for cooperating with the threaded segment of the bolt member and a peripheral edge with a flat side defining an axial slot. The washer member has a central bore with a banking portion that complements the banking feature of the bolt member such that, when the threaded segment is inserted in the central bore, the washer member moves axially and is rotatably fixed relative to the bolt member. The washer member has an axially projecting circumferential wall with radially inward facing engagement teeth for intermeshing with teeth of the lock member. The lock member has a spring finger upstanding from the annular body that is received in the axial of the nut member for fixing the lock member in rotation relative the nut member.

Aspects of the disclosure are directed to a bolt comprising: a body having a head, a circumferential sidewall, a central bore extending at least a portion of a length of the bolt, and a plurality of slots extending through the sidewall from the bore, a plurality of positioning arms at least partially located within an interior of the bolt, and a screw seated within the head, where a position of the screw within the head controls an extent to which the plurality of the positioning arms are extended through the sidewall.

A magnetic fastener and wall covering system include at least one wall panel having a front facing surface, a metallic rear facing surface and a side surface forming any number of different shapes. A plurality of wall fasteners and wall anchors are provided to penetrate and engage a wall. A plurality of magnetic washers are provided having a central aperture for receiving one of the plurality of wall fasteners, and for attracting to the metallic rear surface of the wall panel. The system also includes one or more wall strips having a magnetic top surface and an adhesive back surface.

Provided are a washer that has a non-rotating function and does not damage an attachment surface at the time of fastening and loosening without increasing the number of components, and a fastening structure that prevents accompanying rotation of a bolt by applying the non-rotating function.

Disclosed is a washer 1 is used by being sandwiched between an attachment surface Sa of an object S to be attached and a nut 2 or a bolt head. A first annular protrusion 3 is formed on a side of the attachment surface Sa. An inner shape of the first annular protrusion 3 is larger than an outer shape of the nut 2 or the bolt head.
