<p>A helical thread insert (10) having a removable tang (16) attached to the front end (12) of the insert, a retention device and a removal notch (24) located along the rear portion (14) of the insert. The removable tang (16) is oriented radially inward and 5 includes a 'V' shaped notch (24) oriented along the bottom of the thread to detach the tang (16) at a specified point. The retention device is located at the rear end (14) of the thread insert and prevents counterclockwise, removal rotation of the insert (10) by engaging the female threads of the bore which the helical thread (10) insert is disposed. A removal notch is formed along the inner surface of the insert proximal to the retention device to allow a tool to actuate the retention device inward, away from the female threads of the parent material, to allow relatively free counterclockwise rotation, removal, of the thread insert.</p> |
