Abstract

A fastener includes a head, a shank extending from the head, a first threaded portion having a plurality of first threads formed on the shank adjacent to the head, and a second threaded portion having a plurality of second threads formed on the shank distal from the head. The plurality of first threads have a handedness that is different from a handedness of the plurality of second threads.

Claims (44)

1 . A fastener, comprising:

a head;

an elongate shaft extending from the head and having a first end and a second end, the first end attached to the head;

a first threaded portion having a plurality of first threads formed on the first end of the shank adjacent to the head;

a second threaded portion having a plurality of second threads formed on the second end of the shank distal from the head, the head defining a first terminus of the fastener and the second threaded portion defining a distal, second terminus of the fastener; and

a transition portion intermediate the first threaded portion and the second threaded portion, wherein the transition portion is devoid of threads;

wherein the plurality of first threads have a handedness that is different from a handedness of the plurality of second threads, the plurality of first threads being one of left-handed threads or right-handed threads and the plurality of second threads being the other of the left-handed threads or the right-handed threads; and

wherein the first threaded portion has a diameter that is greater an a diameter of the second threaded portion.

2 . A fastener, comprising:

a head;

a shank extending from the head;

a first threaded portion having a plurality of first threads formed on the shank adjacent to the head; and

a second threaded portion having a plurality of second threads formed on the shank distal from the head;

wherein the plurality of first threads have a handedness that is different from a handedness of the plurality of second threads.

3 . The fastener of claim 2 , wherein:

the plurality of first threads are left-handed threads; and

the plurality of second threads are right-handed threads.

4 . The fastener of claim 2 , wherein:

the plurality of first threads are right-handed threads; and

the plurality of second threads are left-handed threads.

5 . The fastener of claim 2 , wherein:

the first threaded portion has a diameter that is greater than a diameter of the second threaded portion.

6 . The fastener of claim 2 , further comprising:

a transition portion intermediate the first threaded portion and the second threaded portion, wherein the transition portion is devoid of threads.

7 . The fastener of claim 2 , wherein:

the head is one of a hexagonal head, domed head, or 12-point head.

8 - 15 . (canceled)

16 . A fastening system, comprising:

a first component having a first threaded throughbore;

a second component having a second throughbore, the first threaded throughbore and the second throughbore being generally aligned with one another; and

a fastener received through the first threaded throughbore and the second throughbore, the fastener including a head, a shank extending from the head, a first threaded portion having a plurality of first threads formed on the shank adjacent to the head, and a second threaded portion having a plurality of second threads formed on the shank distal from the head;

wherein the plurality of first threads are received by corresponding threads of the first threaded throughbore;

wherein the second threaded portion protrudes from the second throughbore and receives a nut; and

wherein the plurality of first threads have a handedness that is different from a handedness of the plurality of second threads.

17 . The fastening system of claim 16 , wherein:

the plurality of first threads are left-handed threads; and

the plurality of second threads are right-handed threads.

18 . The fastening system of claim 16 , wherein:

the plurality of first threads are right-handed threads; and

the plurality of second threads are left-handed threads.

19 . The fastening system of claim 16 , wherein:

the first threaded portion has a diameter that is greater than a diameter of the second threaded portion.

20 . The fastening system of claim 16 , further comprising:

a transition portion intermediate the first threaded portion and the second threaded portion, wherein the transition portion is devoid of threads.
