MASONRY ANCHOR
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.
1 . A masonry anchor comprising:
a head;
a body integral to the head and extending therefrom; and
at least one helical male thread surrounding the body, the at least one helical male thread including:
a leading face; and
a trailing face substantially perpendicular to the body disposed between the leading face and the head, the trailing face intersecting the leading face at a thread crest.
2 . The masonry anchor of claim 1 wherein the leading face has a substantially straight cross-section.
3 . The masonry anchor of claim 1 wherein the at least one helical male thread comprises a first helical male thread and a second helical male thread.
4 . The masonry anchor of claim 3 wherein a first crest diameter of the first helical male thread is greater than a second crest diameter of the second helical male thread.
5 . The masonry anchor of claim 3 wherein a cross-section of the second helical male thread is substantially V-shaped.
6 . The masonry anchor of claim 3 wherein a lead of the first helical male thread is disposed about 180 degrees from a lead of the second male helical thread.
7 . The masonry anchor of claim 1 wherein the at least one male helical thread includes a plurality of notches extending inwardly from the thread crest.
8 . The masonry anchor of claim 7 wherein each notch of the plurality of notches is substantially v-shaped.
9 . The masonry anchor of claim 7 wherein adjacent notches of the plurality of notches are disposed along the at least one male helical thread about 120 degrees apart.
10 . The masonry anchor of claim 1 comprising a nail point tip.
11 . A masonry anchor comprising:
at least one helical male thread surrounding a body, the at least one helical male thread including:
a leading face;
a trailing face substantially perpendicular to the body and intersecting the the leading face at a thread crest; and
a plurality of notches extending inwardly from the thread crest.
12 . The masonry anchor of claim 11 wherein the at least one helical male thread comprises a first helical male thread and a second helical male thread.
13 . The masonry anchor of claim 12 wherein a first crest diameter of the first helical male thread is greater than a second crest diameter of the second helical male thread.
14 . The masonry anchor of claim 11 wherein each notch of the plurality of notches is substantially v-shaped.
15 . The masonry anchor of claim 11 wherein adjacent notches of the plurality of notches are disposed along the at least one male helical thread about 120 degrees apart.
