Abstract

The present invention includes a fastener comprising: a fastener body having a longitudinal axis and a first external male threaded portion, and two or more through-holes perpendicular to the longitudinal axis of the fastener body in the threaded portion.

First claim

What is claimed is:

1. A fastener comprising:
a fastener body having a longitudinal axis and a first external male threaded portion, and two or more through-holes perpendicular to the longitudinal axis of the fastener body in the threaded portion, wherein each of the through-holes is on a different plane located perpendicular to the longitudinal axis of the fastener, and wherein the two or more through-holes are on a different one of the planes and angle from an adjacent through-hole of the two or more through-holes, is adapted to receive a pin.

2. The fastener of claim 1 , further comprising a head opposite the first external male threaded portion.

3. The fastener of claim 1 , further comprising a second external male thread opposite the first external male thread.

4. The fastener of claim 1 , wherein a longitudinal axis of the two or more through-holes form an angle between 0 and 90 degrees.

5. The fastener of claim 1 , wherein the through-holes are intersecting or non-intersecting.

6. The fastener of claim 1 , wherein the through-holes are sized to hold a pin, wherein the pin is selected from at least one of a split pin, a hairpin cotter pin, a bowtie cotter pin, a circle cotter, or a cotter pin, or a lockwire.

7. The fastener of claim 1 , wherein the first external male threaded portion extends throughout the body to a seat surface on a head portion on the body opposite the first external male threaded portion.

8. The fastener of claim 1 , wherein the first external male threaded portion is configured to matingly engage a fastening member having two or more openings or notches through which the pin is inserted to prevent loosening of the fastening member as a result of vibration.

9. The fastener of claim 1 , wherein the first external male threaded portion and the through-holes are configured to matingly engage a castellated fastener.

10. The fastener of claim 1 , wherein each of the two or more through-holes is on a different plane.
