摘要： 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.

摘要： An anchor (910) for mounting to a hollow wall (W) made of friable material comprises a proximal flanged end (918) adapted to be engaged by a rotatable tool (B) to rotate the anchor (910) about a longitudinal axis (A) thereof and to cause is to gradually engage the wall (W). The anchor (910) also includes a distal end (912) adapted to cut through the wall (W) as the anchor (910) is rotated, and a shank (920) extending between the proximal and distal ends (918, 912). The shank (920) includes at least one expandable leg (924) that is in a collapsed position thereof when the anchor (910) is rotated to mount it to the wall (W) and that is located distally beyond a non visible surface of the wall (W) once the anchor (910) has been mounted to the wall and is in a first position thereof. The wall anchor (910) includes an outer thread (922) that securely engages the wall (W). A threaded fastener (B), e.g. a screw, is adapted to be introduced in the anchor (910) and to threadably engage the same distally of the leg (924) such that sufficient rotation of the threaded fastener (B) retracts the distal end (912) towards the proximal end (918) thereby causing the leg (924) to displace to a laterally expanded position thereof and to engage the non visible surface of the wall (W).

摘要： An undercut anchor system designed for effecting a drill hole and enlarging a lowermost end thereof for insertion and setting of an anchor therein, which utilizes interlocked components surrounding a rod body which can be used as a setting tool in a one-step process to position a bore hole sleeve and an anchor in position within the bore hole. An anchor is positioned on the rod body below the bore sleeve. A cutting tip protrudes from a lower end of the rod body. The cutting tip portion has an operational cutting radius greater than a radius of the rod body. In this manner, an anchor can be inserted within the pre-drilled hole, and, when the anchor has been flanged outwardly by conventional means within the hole, the flange portions of the anchor will rest within the enlarged area, thus securely retaining the anchor in place.
