Abstract
The present invention provides a threaded insert assembly with a locking plate having a non-circular shape and a non-serrated outer edge instead of a conventional circular shaped locking ring having a circular serrated outer edge. The non-circular locking plate is shaped to engage mating edges of a correspondingly shaped recess formed in the anchoring structure so as prevent the insert from rotating out of the anchoring structure once the insert is locked into the plate. The threaded insert is secured to the locking plate by interdigitated serrations swaged into engagement.
