  • Patent number: 10876568
    Abstract: A fastener assembly is provided. The fastener assembly includes an insert having a radial circumference. An annulus extends from the insert and defines an annular end distal from the insert. The annulus further defines a radial cutout section along a length thereof for providing a flex point. The annulus is configured for being radially compressed by a blind hole of a working surface upon tightening of a nut. A nut is positioned adjacent the insert on an end distal the annulus, and a threaded bolt extends from the nut and through the annulus, wherein the bolt is configured to be accepted by the blind hole.

  • Patent number: 9784299
    Abstract: A fastener assembly is provided. The fastener assembly includes a nut having an internally threaded portion and an annulus extending from the nut and configured for receiving the shank of an elongate fastener. A compression collar is configured for deflecting the annulus into at least one of fixed engagement with the shank or to impart a spring bias of the annulus against the compression collar upon tightening of the nut about a working surface.
