Abstract

The present disclosure provides various embodiments of a fastener for securing a wooden object to a metal object, the fastener comprising a head including a tapered body, a shank having a tip, a first portion adjacent to the tapered body of the head, a second portion adjacent to the tip, and a third portion between the first portion and the second portion. The shank having a longitudinal axis extending from the head to the tip, a helical thread formation extending from the shank, a first wing extending from the second portion of the shank at a first angle relative to the longitudinal axis of the shank, and a second wing extending from the second portion of the shank at a second angle relative to the longitudinal axis of the shank. The first wing and the second wing have a same shape as each other, extend from the second portion of the shank at offset positions relative to each other along the longitudinal axis of the shank, and wherein the offset positions of the first wing and the second wing are partially overlapping relative to each other along the longitudinal axis of the shank.

Claims (4)

1. 5 10 15 A fastener for securing a wooden object to a metal object, the fastener comprising: a head including a tapered body; a shank having a tip, a first portion adjacent to the tapered body of the head, a second portion adjacent to the tip, and a third portion between the first portion and the second portion, the shank having a longitudinal axis extending from the head to the tip; a helical thread formation extending from the shank; a first wing extending from the second portion of the shank at a first angle relative to the longitudinal axis of the shank; and a second wing extending from the second portion of the shank at a second angle relative to the longitudinal axis of the shank, wherein the first wing and the second wing have a same shape as each other, wherein the first wing and the second wing extend from the second portion of the shank at offset positions relative to each other along the longitudinal axis of the shank, and wherein the offset positions of the first wing and the second wing are partially overlapping relative to each other along the longitudinal axis of the shank.
2. The fastener of claim 2, wherein the first angle is approximately 10 degrees offset from a plane that extends through and along the longitudinal axis of the shank. 20 25
3. The fastener of claim 3, wherein the second angle is approximately 10 degrees offset from the plane that extends through and along the longitudinal axis of the shank.
4. The fastener of claim 1, wherein the first wing and the second wing each include a semi cylindrical shape.
