Abstract: A modular system facilitates packaging, marking, handling, sterilizing, tracking, tagging and storing small components such as surgical screws. A small, suitably cylindrical or similar cell receives a screw or other component and seats the component in a predetermined orientation. A complementary cap is adapted to engage the cell from above, closing the top and retaining the component in the cell. The cap is also adapted for use as a tool for handling the cell and the component contained therein. A coupling between the cell and the the cap allows the cap to be snapped securely on the cell under manual pressure; the coupling is further adapted to release on application of sufficient bending moment across the co-axis of the cell and cap.
