Abstract

According to aspects of one or more exemplary implementations, disclosed is a flanged ribbed nut, or FRN, having a head above an extended flange formed integral to said head, and a neck integral to and extending from said flange opposite said head, and a threading guide in fluid communication with said head, flange and neck, and having at least two interfering ribs formed therein.

Claims (21)

1. A fastening method, the method comprising:

threading a ribbed nut with a threading guide containing ribs separated by gaps onto a threaded fastener, said threaded fastener being constructed of a material which is harder than said ribbed nut;

forming lips of displaced rib material at least partially extending into said gaps during the threading of said threaded fastener onto said ribbed nut; and

inserting a beveled area into a guide hole, wherein the beveled area is above a neck of the ribbed nut and extends at least one third of a radial length of a flange of the ribbed nut;

wherein said ribbed nut has at least two buttresses connecting a head of the nut to the flange such that the flange will withstand a greater load than a solid hexagonal nut of the same material.

2. The fastening method of claim 1 wherein the threading guide is a generally circular annular wall from which said ribs extend and traverse longitudinally.

3. The fastening method of claim 1 , the method further comprising affixing one or more materials via guide holes between said threaded fastener and said ribbed nut.

4. The fastening method of claim 1 , further comprising a plurality of buttresses located in an array connecting the head of the nut to the flange;

whereby the flange will withstand a greater load than a solid hexagonal nut of the same material.

5. The fastening method of claim 1 , wherein the threading guide extends beyond both sides of the flange.

6. A method of fastening, the method comprising:

placing a guide hole in a first material;

placing a neck of a plastic flanged nut with a threading guide therein in said guide hole, the flanged nut having malleable ribs running axially from an annular wall of the flanged nut through the neck;

threading a threaded fastener into the threading guide, said threaded fastener being constructed of a material which is harder than said ribs; and

deforming the malleable ribs to at least partially fill in around threads of the threaded fastener with displaced rib material at least partially extending into gap spacing during the threading of said threaded fastener into the threading guide, wherein said flanged nut has at least two buttresses connecting a head of the nut to a flange of the flanged nut.

7. The method of claim 6 , wherein said flanged nut has a stepped flange which fits into said guide holes.

8. The method of claim 6 , wherein the threading guide is a generally circular annular wall from which said ribs extend and traverse.

9. The fastening method of claim 6 , further comprising:

a plurality of buttresses located in an array connecting the head of the nut to the flange;

whereby the flange will withstand a greater load than a solid hexagonal nut of the same material.

10. The fastening method of claim 6 , wherein the threading guide extends beyond both sides of the flange.
