Abstract: An anchor bolt for use in a hole in a base material is provided and includes a stud, a sleeve disposed about the stud and a retainer nut, disposed in operable communication with the stud and having a dimension measured from a central axis of the hole that is at least as large as a corresponding dimension of the hole.

Abstract: A masonry anchor includes a head and a body integral to the head and extending therefrom. At least one helical male thread surrounds the body and includes a leading face and a trailing face substantially perpendicular to the body disposed between the leading face and the head. The trailing face intersects the leading face at a thread crest.

Abstract: Disclosed is an anchor bolt including a wedge having a surface with a plurality of protrusions and a sleeve in operable communication with the surface. Furthermore, the sleeve is expandably receptive to the surface.

Abstract: An anchor for masonry. The anchor is relatively smooth walled and is forcibly driven into a hole formed in masonry or other suitable material for purposes of attaching fixtures. When driven into the hole, a shaped portion of the anchor is deformed in such a manner as to facilitate a 360 degree or greater bearing surface with the holes of wall. The walls of the hole impose forces onto the shank along this bearing surface which tend to deform shank into alignment with the hole by primarily elastic deformation so that the resulting frictional forces between the shank and the wall resist dislodgment from the hole.

Abstract: A fixing assembly for attaching a fixing to a workpiece, having a fixing and a resilient member. The fixing includes an aperture and is adapted for mating with the workpiece and holding the fixture. The resilient member includes a first portion secured in the aperture, and a second portion adapted for frictional engagement with a nosepiece of a fastener-driving tool.
