A rivet-like bone anchor has a floating washer at its head that can adapt to an angled bone surface and, thereby, better secure a tissue thereto. The anchor includes a rivet, an expandable sleeve, and a washer. The rivet includes a head and an elongate body having proximal and distal ends, the head being mounted on the proximal end of the elongate body. The expandable sleeve has an inner bore adapted to receive the rivet body. The washer “floats” at a proximal end of the sleeve. As the rivet is inserted into sleeve, the sleeve expands into an interference fit with the bone. The head of the rivet, moreover, forces the floating washer into contact with the tissue at an angle that conforms to that of the underlying bone surface. A deployment tool permits the anchor to be deployed without application of unnecessary counterforce. The tool includes an outer tube, the distal end of which can hold the anchor housing, e.g., via a screw fit. A rod, which is slidably disposed within the bore of the tube, can be used to push the rivet into the expandable sleeve so that the sleeve expands into the bone, so that the floating washer is forced into position against the bone surface, and so that anchor is broken away from the housing. This can be effected, for example, by squeezing the distal ends of the outer tube and the rod together, e.g., in the manner that the end of a syringe is squeezed.

A bonding washer for making electrical connection between two metal pieces that are to be mechanically fastened together.

Captive fasteners and alignment posts for allowing ceiling fan blade arms to be easily and safely mounted onto ceiling mounted motors. Fasteners such as Philips head screws, regular head screws and bolts can be held captive in place on blade mounting arms with rubber grommet type washers. The grommet type washers have portions that can be sandwiched between the fastener head and the mounting arms and sandwiched between the mounting arms and rotating member on the ceiling fan motor in order to reduce vibration noise and movement Alternatively, novel captive fasteners having a thicker neck portion between a threaded end a the bead can be positioned within the grommet type washers. A second embodiment of the captive fastener is floatingly supported within the mounting arm between the fastener head and a ledge within the mounting arm through-hole, with an enlarged threaded end of the fastener on the opposite side of the ledge. A tip portion of these captive fasteners can remain extended from the upper surface of the mounting arm and is used to guide the fasteners to the mateable threaded openings on the bottom of the rotating member on the motor. A third embodiment incorporates at least one alignment post and mateable receiving hole for allowing the mounting arm to be properly aligned with the correct position on the rotating member. The alignment posts can be tapered, rounded or having flat sides such as squares and hexagons, to further position and hold the mounting arms to the rotating members on the motor. The alignment post(s) can be located on the upper surface of the mounting arms or extend downward from the rotating member of the motor. With the alignment posts either or both captive fasteners or regular fasteners such as bolts, regular head and Philips head screws can be used. Additionally, the alignment post(s) can be used without the grommet shaped washers. The alignment members and captive fasteners eliminate wobble effects by evenly attaching the mounting blade arm to the ceiling fan motor.
