Tanged screw thread insert with improved removability

A thread insert, comprising:

• a helical-shaped insert defining a plurality of coil sections including opposing first and second coil end sections;
• each coil section having an inner surface and an outer surface defining a thread shape;
• a removable tang radially extending inwardly from the first coil end section;
• a finished end of the second coil end section;
• a continuously curved surface operably created at the finished end;
• a tangent point created where the continuously curved surface tangentially meets the outer surface of the second coil end section;
• and
• a notch disposed in the first coil end section proximate to the tang and positioned between the inner and outer surfaces;
• wherein the tang is removable from the insert by mechanical failure at the notch.

A thread insert, comprising:

• a helical-shaped insert defining a plurality of coil sections including opposing first and second coil end sections and a coil longitudinal axis;
• each coil section having an inner surface and an outer surface defining a thread shape;
• a removable tang inwardly radially extending from the first coil end section and substantially transverse to the coil longitudinal axis;
• a finished end of the second coil section;
• a continuously curved surface operably created at the finished end of the second coil section;
• a tangent point operably created where the continuously curved surface tangentially meets the outer surface of the second coil end section;
• a V-shaped notch disposed in the first coil end section proximate to the tang and positioned between the inner and outer surfaces, the V-shaped notch operable to create a failure point in the first coil section for removal of the tang;
• and
• a second notch created in the second coil section proximate to the continuously curved surface, the second notch having a contact surface operable to assist in removal of the insert from an installed position.
