Abstract
A wall anchor for insertion in wall board and having a cylindrical body with an outer thread and an axial through passage extending from a flanged proximal end to a saw-tipped distal end. The cylindrical body comprises a proximal extension and a distal extension of approximately the same length equal to the width of wall board. The flange at the proximal end may be provided with locking tabs and the saw-tipped end may be provided with mashing teeth on a circumference of revolution smaller than that of the sawing teeth.
Claims8
A wall anchor for insertion in a wall, said wall anchor comprising a cylindrical body having an outer thread and an axial through passage extending from a flanged proximal end of said body to a saw-tipped distal end of said body, saw teeth extending distally from said distal end in the configuration of peaks separated by flat valleys circumferentially spaced about said distal end surrounding said through passage, said flat valleys comprising the distal edge of said distal end, means extending axially along said through passage from said proximal end for receiving the threads of a screw fastener and recess means at said flanged proximal end for receiving a drive tool for rotating said anchor for sawing through the wall with said saw-tipped distal end.
A wall anchor for insertion in a wall, said anchor having a distal extension octagonal in cross-section with short sides and long sides, the distal ends of said extension comprising an octagonal edge having short sides and long sides with saw teeth extending distally from said short sides of said octagonal edge for sawing through the wall and teeth means positioned rearwardly of said saw teeth and extending distally from said long sides of said octagonal edge for mashing wall material sawed loose by said saw teeth, said teeth being in the configuration of peaks separated by curved valleys circumferentially spaced about said octagonal edge.
