Abstract
The present disclosure provides various embodiments of a winged threaded fastener primarily suited to be used to connect a wooden object to a metal object. The fastener includes a head, a shank, a helical thread formation extending from the shank, a first wing extending from the shank, and a second wing extending from the shank. In various embodiments, the wings are offset along the longitudinal axis of the shank with respect to each other and are angled with respect the longitudinal axis of the shank.
Claims20
A fastener comprising:
- a head;
- a shank having a tip, a first portion adjacent 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, the first wing having a semi-cylindrical shape;
- and
- a second wing extending from the second portion of the shank, the second wing having a semi-cylindrical shape, 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, wherein the first wing or the second wing extends at an angle relative to the longitudinal axis of the shank.

A fastener comprising:
- a head;
- a shank having a tip, a first portion adjacent 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, the first angle being approximately 10 degrees offset from a plane that extends through and along the longitudinal axis of the shank;

A 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 extend from the second portion of the shank at offset positions relative to each other along the longitudinal axis of the shank, 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.

A 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 and the first wind and the second wind extend from the second portion of the shank at offset positions relative to each other along the longitudinal axis of the shank, wherein the offset positions of the first wing and the second wing are not overlapping along the longitudinal axis of the shank.
