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 self-piercing rivet comprises a bearing flange and a piercing end with a radially-expandable hollow tubular body extending axially between the flange and the piercing end, the body comprising a cylindrical first portion that is adjacent to said flange, a cylindrical second portion that is adjacent to said piercing end, and an expandable barrel-shaped third portion between the cylindrical first and second portions, and a bushing arranged in the second portion that is designed to be driven in axial translation towards the flange. The bushing extends axially inside the third portion of the tubular body in such a manner that it is inserted into said first portion of the body when the third portion is completely expanded. The third portion of the body is designed to produce, before being deformed radially, an abrasion or deburring effect on the peripheral edge of a hole being pierced by said piercing end.

The disclosure relates to an anchor system having an internally threaded anchor and a bolt or shaft screwed together with said anchor for holding an add-on component in a hole that is pre-drilled into a wall made of concrete or brick work, characterized in that the bolt of shaft comprises a coil spring which is wound suitably to the inner thread of the internally threaded anchor and screwed into said inner thread.

A longitudinal channel with increased holding strength, configured for use as an anchoring element for an anchor used in supporting objects on a substrate and a method for the production thereof and an anchor. The channel has a generally U-shaped axial cross section in at least a portion thereof with, the U-shaped cross section being comprised of longitudinal side walls and a longitudinal base connection between the side walls. The side walls have free edges configured for holding contact with the substrate. A portion of the free edges of the channel are covered with a planar continuous surface material which is co-extensive with non-covered free edges whereby the planar continuous surface material and the free edges provide a planar holding surface with greater surface area than that of the free edges alone for the increased holding strength.

A self-drilling anchor including a screw and an anchor body configured to receive a shank of the screw, the anchor body including: a flange at an end oriented toward a head of the screw, a threaded portion, a deformable expansion portion between the flange and the threaded portion, and a rotation locking mechanism preventing rotation of the anchor body relative to the wall. The threaded portion is configured to engage with the screw thread and advance in a direction of the flange, by deforming the expansion portion, when the screw is screwed into the threaded portion. The anchor body further includes a piercing element at the opposite end from the flange, the anchor including a fastening mechanism between the screw and the anchor body, the fastening mechanism being detachable by a torque, applied between the screw and the anchor body, equal to or greater than a predetermined torque.

An anchoring device for a attaching a plurality of substrates when only one side of the substrates is accessible.

An internal cake support device for forming a multi-tiered cake. The device comprises a shaft having a first end and a second end and a head is provided at a first end. The device comprises a first measurement scale for measuring a linear dimension from the second end of the shaft. The device comprises a second measurement scale for measuring a linear dimension from the first end of the shaft.

An anchor fastener includes a head, a generally cylindrical shaft extending from the head, and a base at a distal end of the shaft. The shaft includes a helical thread on an outer surface and a self-drilling tip at its distal end adjacent the base. The base is frangibly connected to the distal end of the shaft by at least one web of frangible material separable from at least one of the base and the shaft under application of a force to the shaft.

A setting device for a self-drilling anchor bolt of the present invention includes: a drive shaft, one end thereof having a shank for connecting to an impact tool, and another end being a setting part for pushing the self-drilling anchor bolt axially; a coupling, partially surrounding the drive shaft along an axis, and being supported on the drive shaft in such a way as to be incapable of relative rotation while being axially moveable at least locally; and a releasable locking component, disposed between the drive shaft and the coupling; in a locked position, the locking component is coupled to an extremity of an anchor rod such that the anchor rod is fed axially with rotational striking into a receiving material, and in a released position, the drive shaft strikes a sleeve to advance axially along the anchor rod and expand at an expansion part.

A panel fastener and panel fastening system are provided. The panel fastener includes a body having a collar and an elongated shank extending from the collar. The elongated shank defines an interior space and having a penetrating tip disposed at an end opposite of the collar. The panel fastener also includes a substrate fastening portion configured to be driven into a substrate and a holding mechanism connected to the substrate fastening portion and configured to engage the substrate.
