摘要

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.

主权项

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.
