Abstract

A truss fastener which includes a shaft having a head and a tip. Threading extends along the shaft from the tip end toward the head end of the shaft. The threading is interrupted, abbreviated, and/or otherwise separated by wings projecting from the surface of the shaft. The interrupting projection extends in a generally oblique orientation to the center axis of the fastener.

Claims (27)

1. A truss fastener comprising:

a shaft having a center axis, a tip and a head, said shaft including a profiled portion located proximate said tip and a cylindrical portion located between said profiled portion and said head;

a first threaded portion on said cylindrical portion;

a second threaded portion on said profiled portion; and

a wing positioned on said profiled portion between said first and second threaded portions, said wing protruding radially relative to said center axis from a surface of said shaft and extending in an oblique orientation relative to the center axis along a portion of said shaft surface.

2. The truss fastener of claim 1 , wherein the wing includes an arcuate portion having a cutting edge.

3. The truss fastener of claim 1 , wherein the wing includes a trailing portion which is substantially perpendicular to a surface of the profiled portion.

4. The truss fastener of claim 1 , wherein the profiled portion has a tapered configuration.

5. The truss fastener of claim 1 , wherein there are a plurality of wings protruding from the shaft surface.

6. The truss fastener of claim 1 , wherein the second threaded portion is proximate an entry end of the wing and the first threaded portion is proximate a trailing portion of the wing.

7. The truss fastener of claim 6 , wherein the first threaded portion has about 9 threads per inch and the threads have a thread angle of about 40°.

8. The truss fastener of claim 6 , wherein the wing protrudes outward from the center axis to a lesser distance than the first threaded portion protrudes outward from the center axis.

9. The truss fastener of claim 1 , wherein the wing protrudes outward from the central axis to a greater distance than the distance from the center axis to a surface of an unthreaded portion of the substantially cylindrical portion of the shaft.

10. The truss fastener of claim 1 , wherein the head has a tool engagement portion and a tapered neck which extends between a substantially cylindrical portion of the shaft and a lip.

11. The truss fastener of claim 10 , wherein the tool engagement portion is hexagonal.

12. A truss fastener and engineered lumber material assembly comprising:

at least one engineered lumber material element having a bore hole formed by the truss fastener;

the truss fastener having a shaft with a center axis extending into the bore hole of the engineered lumber material, a tip, a profiled portion proximate the tip, and a head in contact with a surface of the engineered lumber material, said shaft having a threaded cylindrical portion engaged with the engineered lumber material, said threaded portion having threads that protrude a first distance outwardly from the center axis;

a wing extending a second distance outwardly from the center axis of the shaft into a portion of the laminated construction material and extending in an oblique orientation relative to the center axis along a portion of the shaft surface, said first distance being greater than said second distance.

13. A method of fastening engineered lumber materials together comprising:

positioning at least two engineered lumber construction members in surface-to-surface relationship;

placing a distal end of an engineered lumber material fastener in contact with a surface of one of the engineered lumber members;

rotatably driving the fastener such that a threaded portion of a shaft of the fastener engages the engineered lumber members;

reaming an engineered lumber members portion adjacent to a surface of the shaft with a wing which extends from the shaft in an oblique orientation relative to a center axis of the shaft, said wing extending along a portion of the shaft surface;

engaging the reamed portion with a threaded portion on a cylindrical portion of the shaft; and

seating a head of the fastener against the surface of the one engineered lumber member.

14. The method of fastening engineered lumber members together of claim 13 , wherein the step of reaming includes forming a bore hole in the engineered lumber members.
