A threaded insert is designed to snap into a standard bone plate hole. The insert has an upper section divided into sectors by slots, a lower section having deflectable tabs with external projections, and a central threaded hole. When a standard bone screw is tightened in the insert, the insert rigidly fixes the screw to the plate by collapsing the threads of the insert onto the threads of the screw, and by expanding the sectors of the upper section to clamp the bone plate.
