ABSTRACT:
A device for locking a threaded insert into a prepared hole in a parent material. The device includes a locating portion, a locking portion and a gripping portion which is removed upon installation. The locating portion comprises a finger which is positioned in a preformed slot in the external threads of the threaded insert. The locking portion, which extends outwardly from the locating portion, is driven across the corresponding threads of the parent material to shear and distort the threads and lock the insert in place. The gripping portion which extends outwardly from the locking portion is used by the installer to position the device during installation and is then broken off.
