A star shaped fastener having at least three fins radiating from a central core with the fin-included angle in a five finned embodiment being between 72 to 98 degrees which configuration reduces the fabricated material by 50% and increases the surface area by 15%-85% compared to a common round nail of equal radius.

A series of drywall screws are nested together and individually seated with a special driving tool after separation from one another. Each screw is hollow and has interior and exterior screw threads. One end of the screw has a hollow flat head and the body tapers downwardly to a bottom portion having a diameter less than half the diameter of the first end. A drill bit having an eccentric point drills a bore having a diameter greater than the diameter of the drill bit so that the bore operatively receives the screw.

A wire straightener and multiple preform rollers prepare a continuous length wire for further forming by multiple form rollers having multiple spaced apart notches formed in an annular edge of the rollers. Some notches skip a section of the wire to be headed, and other notches serve to form barbs in the wire. In a first embodiment, after the formed wire is fed to a gripper housing where the wire is cut to a predetermined length, the skipped section is punched to create the fastener head. In a second embodiment, the formed wire is cut and fed to a rotary heading machine.

Apparatus includes a mandible alignment device and a jaw pattern jig to prepare a one-piece metal dental implant for insertion into a patient's mouth. The alignment device has a central scissors member with a rear positioned thumb wheel controlling the longitudinal spread of the scissors blades. A front portion of a longitudinal angle adjustment member mounted over the scissors holds an anterior foot portion of a dental implant. A rod integral with the end of each scissors blade supports a housing holding a ramus member portion of a dental implant. After a pattern is determined by the alignment device, it is locked into the jaw pattern jig and the one-piece metal dental implant is bent to shape to substitute for the anterior foot and ramus members removed from the alignment device.

A star shaped fastener having at least five spaced vertical cups and edges about a central core with the included angle being 90. degree. reducing the fabricated material by 50% and increasing the surface area by 15% compared to a common round nail of equal radius. The holding power is significantly enhanced by compression laterally and vertically into cups, shoulders therein and/or a taper of less than 14. degree.

A horizontally extending reinforcing bar having a central core in transverse cross-section exhibiting at least three radial fins projecting outwardly symmetrically from the center of the bar to its outer edge. Each pair of adjacent fins define a valley between them containing a pattern of raised surface area. Two in-line reinforcing bars are held together by a coupling device having a housing with multiple flexible inwardly projecting plates from grooves in an inner wall. The plates flex in the direction of insertion of a reinforcing bar and exert a force to prevent removal of the bar.

A wire straightener, and multiple preform rollers prepare a continuous length wire for further forming with multiple form rollers having multiple spaced apart notches on an exterior surface edge of the rollers. The notches cause a section of the wire to be non-formed. After the formed wire is fed to a gripper housing where the wire is cut to a predetermined length, the non-formed section is punched to create the fastener head. The end section of the fastener opposite the head is tapered and the finished fastener is ejected from the machine.

A machine for making concrete reinforcing bars, known as rebars, from wire stock having a round cross section. A preform roller station cold works the round cross section of the wire stock into the shape of a polygon. A first form roller station cold works the polygonal cross section into a cross section having a central core and radial fin members extending therefrom. A second form roller station further reduces the diameter of the central core, and further increases the radial extent of the fin members. A third form roller station reduces the core still further, and again increases the radial extent of the fins, imparts shoulder members that provide an anti-longitudinal slip function at preselected intervals along the extent of the rebar, and roughens the rebar.
