An anchor for wallboard installation includes an elongated anchor body including a driving end and a wall boring end. The anchor body has a main body portion running from the driving end toward the wall boring end. The wall boring end includes a plurality of axially cutting extending teeth. The anchor body includes an internal bore and diametrically opposed slots to facilitate split of an end portion of the anchor body when the anchor is installed in a wall and a fastener is inserted for mounting an object.

A high capacity radial-fit coupling bolt (or expanding sleeve bolt) has a pair of tapered sleeves about a shank of a bolt to which can be applied a tensioning load. An extrudable ring, or a compression ring, is interposed between a head nut or head flange at one end of the shank, and one end of an inner sleeve. A tensioning load is applied to the shank, the inner sleeve causing the outer sleeve to expand diametrically. At a preset load limit, the extrudable ring is extruded through at least one bore in a drive piston between the head nut and the extrudable ring, to allow shank to move relative to the inner sleeve until the tensioning load is fully applied. Alternatively, a drive member is provided between the head nut or head flange and the compression ring, and at a preset limit, the compression ring allows the shank to move relative to inner sleeve until the tensioning load is fully applied. The preset limit will typically correspond to the force required to fully expand the outer sleeve.

A fastener including a body having a threaded portion and an opposing, tapered portion, where the tapered portion includes an outwardly angled surface, and a sleeve movably connected to the body. The sleeve includes a plurality of fingers at least partially separated from each other, where each of the fingers includes at least two, axially spaced gripping members protruding from the body. When the fastener is inserted in a borehole formed in a substrate and a fastening member is threaded onto the threaded portion and tightened, the sleeve progressively moves along the angled surface causing the fingers to move outwardly and at least one of the gripping members to engage an inner surface of the substrate forming the borehole to secure the fastener in the borehole.

Fishing lures with arrangements for attaching fishing lines thereto.

A fastening assembly includes a panel, a fastener and a primary anode insert. The panel defines an aperture and the fastener includes a shaft portion disposed within the aperture. The primary anode insert may be disposed adjacent to a reaction region of the fastener. Alternatively, the fastening assembly may include a fastener and a primary anode insert. The fastener includes a shaft portion which is configured to be disposed within at least two aligned component apertures. The primary anode insert may be also be disposed adjacent to a reaction region of the fastener.

A joint block suitable for both rectangular pipes and round pipes has a base having a plurality of separated elastic petals evenly and peripherally disposed at an end of the base. A through aperture is disposed in a center position of the base, another end of the base has a circular ring, and the circular ring comprising at least a facet providing a contact surface. An outer surface of the circular ring contacts an inner surface of the round tubular railing, the contact surface contacts an inner surface of the rectangular tubular railing, and the elastic petals pushes against the inner surface of the round tubular railing or the rectangular tubular railing.

A fastening element comprising a first plate with at least two pin-shaped connection elements extending from the first plate, and a second plate with at least one recess, in particular two recesses, for the pin-shaped connection elements, wherein the at least one recess is formed such that the connection elements are insertable into the at least one recess, and wherein the pin-shaped connection elements comprise stop elements arranged, in particular rigidly arranged, on the same and acting in the longitudinal direction of the connection elements and against which the second plate can be brought into abutment when the connection elements pass through the recess of the second plate.
