Abstract: An anchor assembly (A) for hollow walls comprises an anchor body (400) and a toggle member (231) that is displaceable between a first position wherein the toggle member (231) is substantially aligned with the anchor body (400) such that the anchor assembly (A) can be inserted in the wall (W) via a cutting distal end (325) of the toggle member (231), and a second position wherein the toggle member (231) extends behind the wall (W) at an angle relative to the anchor body (400) which extends through the wall (W). The toggle member (231) is held captive in the first position but is released and then rotated to the second position by a fastener (218) introduced in the anchor body (400). The fastener (218) threadably engages the toggle member (231) thereby drawing the toggle member (231) against a hidden side of the wall (W).

Abstract: A lock nut system includes a nut, a keeper engagement with the nut to inhibit movement of the keeper relative to the nut, and a keeper retaining member. The keeper has a radially inner side configured to engage a shaft to inhibit rotational movement of the nut relative to the shaft when the keeper engages the nut and a radially inner side engages the shaft. The keeper retaining member is secured to the keeper and is engageable with the nut to hold a keeper axially such that keeper is engaged with the nut. A cover member is located on an opposite side of the keeper retaining member relative to the nut and engaged to the keeper retaining member to inhibit a separation of the cover member from the keeper retaining member in such that that the separation of the cover member from the keeper retaining member provides a visual indication to a user.

Abstract: A blind fastener device for fastening at least two workpieces, including a sleeve, an expander having a tensioning section, a locking section, and an expansion section, and a nut. A portion of the expander passes through the sleeve to cooperate with the nut so that relative rotation of the expander and nut draws the expander's distal end toward the sleeve's proximal end thereby drawing a portion of the expansion section of the expander into a structural region located on the sleeve and expanding at least a portion of the sleeve's structural region, and drawing a portion of the locking section past the sleeve's distal end toward the sleeve's proximal end and deforming at least a portion of the sleeve's distal end to a locked state. The sleeve may be configured as a multi-section sleeve having a sleeve retainer to locate the sections in a predetermined relationship.

Abstract: A hanger for a shower curtain comprises two opposing direction hooks and a captive roller for riding along the top of a curtain rod. A base part of the hanger has a hub with both a hook and a cradle at the lower end of a shank. The hook faces in one planar direction and a cradle faces in the opposite direction. The base comprises a spindle lying in said plane; the roller is rotatably captured on said spindle. The cap portion of a closure mounts on the free end of the spindle to keep the roller in place. The closure comprises a hook portion at the end of the shank; the hook portion mates with the cradle of the base. Preferably, the closure is rotatable about the spindle end, so that when the closure hook is disengaged from the cradle there is an opening which enables the hanger to be mounted and dismounted from a curtain rod.

Abstract: A multi-thread screw includes a head end, a shank and a tapered end. Both a high thread and a low thread begin on the tapered end and extend onto the shank. A set of intermediate threads are located on the shank portion only and overlap with and intersect at least part of the high thread.

Abstract: A split nut and assembly steps for fitting the nut around an exposed portion of anchor bolt having no convenient access for conventional nuts to engage. The split nut includes first and second nut halves, and each nut half has an interior surface having a threaded half cylinder that, when aligned with the other threaded half cylinder and joined along joining surfaces, forms a threaded opening. The two half nuts may be connected by connectors that are inserted into penetrations that extend through at least a portion of both half nuts. At least one end of the penetration extends from the joining surface through the exterior surface of the half nut so that the connector may be inserted into the penetration. The exterior surface of both half nuts also include flat that, when the half nuts are joined, are dimensioned to form opposed parallel drive surfaces configured to be engaged by a wrench for screwing the split nut onto the bolt.

Abstract: A bolt for securing timber to any other material, comprises: a bolt head with a series of spiked teeth on its underside; a cylindrical bolt rod extending from the bolt head is threaded and split into two rods at its free end, so as to define a slot therebetween. In use a user drills a hole through pieces of timber to be secured together, and hammers the bolt through the hole. The spiked teeth on the bolt head lock into the timber, securing the bolt at one end. At the free, split end of the bolt rod, a washer and nut are tightened onto the bolt. A cold chisel is hammered into the slot between the split ends of the rod, bending the ends outwards and thus preventing the nut from loosening.

Abstract: A tacking fastener for securing workpieces together to form a temporary assembly is provided that includes a stem and a sleeve. The stem includes a proximal end portion, a central portion, and a distal end portion. The stem further includes a head disposed at the proximal end portion, the head defining a distal face having a gripping feature. The sleeve includes a flange disposed at the distal end portion, the flange defining a proximal face having a gripping feature. The sleeve is disposed around the stem and configured to form a tacking rivet upon installation of the tacking fastener. The sleeve is plastically deformed during installation to form a plurality of bulbs, thereby being capable of securing workpieces of varying grip length. The stem and the tacking rivet remain within the workpieces after the workpieces are secured.

Abstract: A self-clinching fastener for insertion into ductile sheets of varying thicknesses has increased push-out and torque-out resistance. The self-clinching fastener includes a plurality of radial projections and spline teeth that embed into the ductile sheets, causing the material to cold flow into a recess, thereby permanently clinching the self-clinching fastener to the ductile sheet.

Abstract: Punch pins which have further extending lobes, and which are designed to punch sockets that have deeper flutes while not having lobes which extend further toward a center axis of the fastener. Using such a punch pin to form a socket in a fastener provides that the resulting socket has flutes which are deeper than they otherwise would be, without having to provide corresponding lobes which extend further toward the center axis of the socket. This extra deepness in the flutes helps to provide extra room for a coating to deposit.

Abstract: A blind fastener device for fastening workpieces, including a sleeve, an expander having a locking section and an expansion section, and a separate and distinct tensioning section configured to mechanically cooperate with the expander. One end of the tensioning section is configured as a tensioning section gripping region, which may be formed as the head of a bolt. A portion of the tensioning section passes through the sleeve to cooperate with the expander so that relative rotation of the tensioning section and the expander draws the expander distal end toward the sleeve proximal end and ultimately deforming a portion of the sleeve distal end to a locked state. The sleeve may be configured as a multi-section sleeve having a sleeve retainer to locate the sections in a predetermined relationship.

Abstract: An apparatus includes a nut plate with a plurality of retention tabs integrally attached to the nut plate. A spring assembly is contained with the plurality of retention tabs. The apparatus also includes a nut retained by the retention tabs.
