Abstract
Official abstract text for this publication.
A fastener includes an elongated shank body having one or more helical threads and a head connected with the body. The head can include a drive design indentation extending into a first side of the head that is configured to be engaged with a drive tool. The head also includes radially projecting saw teeth extending around an outer perimeter of the head.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fastener comprising: an elongated shank body having one or more helical threads; and a head connected with the body, the head including a drive design indentation extending into a first side of the head that is configured to be engaged with a drive tool, the head having radially projecting saw teeth extending around an outer perimeter of the head. 2 . The fastener of claim 1 , wherein the radially projecting saw teeth are curved in a clockwise direction. 3 . The fastener of claim 1 , wherein the radially projecting saw teeth include curved outer edges that are convex from the outer perimeter of the head to intersections with straight edges that radially project from the outer perimeter of the head. 4 . The fastener of claim 1 , wherein the radially projecting saw teeth of the head form a serrated outer edge of the head. 5 . The fastener of claim 1 , wherein the head includes ramped surfaces that are opposite of the radially projecting saw teeth on a second side of the head. 6 . The fastener of claim 5 , wherein the ramped surfaces are oriented at oblique angles to the first side of the head. 7 . The fastener of claim 1 , wherein the head has a circular shape with the radially projecting saw teeth projecting outward from the circular shape. 8 . A fastener comprising: an elongated shank body having one or more threads; and a head connected with the body and configured to be engaged with a drive tool, the head having curved saw teeth extending around an outer perimeter of the head. 9 . The fastener of claim 8 , wherein the curved saw teeth radially project from the outer perimeter of the head. 10 . The fastener of claim 8 , wherein the saw teeth are curved in a clockwise direction. 11 . The fastener of claim 8 , wherein the saw teeth include curved outer edges that are convex from the outer perimeter of the head to intersections with straight edges that radially project from the outer perimeter of the head. 12 . The fastener of claim 8 , wherein the saw teeth of the head form a serrated outer edge of the head. 13 . The fastener of claim 8 , wherein the head includes ramped surfaces that are opposite of the saw teeth on a second side of the head. 14 . The fastener of claim 13 , wherein the ramped surfaces are oriented at oblique angles to the first side of the head. 15 . The fastener of claim 8 , wherein the head has a circular shape with the saw teeth projecting outward from the circular shape. 16 . A fastener comprising: an elongated shank body; and a head connected with the body, the head having curved radially projecting saw teeth extending around an outer perimeter of the head. 17 . The fastener of claim 16 , wherein the head also includes a drive design indentation extending into a first side of the head that is configured to be engaged with a drive tool. 18 . The fastener of claim 16 , wherein the saw teeth are curved in a clockwise direction. 19 . The fastener of claim 16 , wherein the saw teeth include curved outer edges that are convex from the outer perimeter of the head to intersections with straight edges that radially project from the outer perimeter of the head. 20 . The fastener of claim 16 , wherein the saw teeth of the head form a serrated outer edge of the head.
