Patent ID: 10145405

Abstract:
A self-tapping insert has at least one interior die slot which repairs damaged threads on a fastener used with the insert. The self-tapping insert is used for providing replacing threads in a workpiece. The self-tapping insert has a cylindrical body with a top and a bottom, an exterior portion and an interior portion. The exterior portion has a cutting thread wrapped around the exterior surface, where the cutting thread sequentially intersects a cutting slot disposed in a generally axial orientation along the exterior portion. The interior portion has a screw thread for receiving the fastener. The screw thread intersects the die slot having a die slot leading edge and a die slot trailing edge. A screw thread leading edge is defined by each sequential intersection of the screw thread with the die slot leading edge and a screw thread trailing edge is defined by each sequential intersection of the screw thread with the die slot trailing edge.
