That's the way you proceed:
First update your TARGET 3001! version free of charge (menu Help/Free Update). Then renew the database by the menu "Update" in the database browser. This is free of charge as well. Close all dialogs and open a front panel project. Now open the component database by clicking this milling tool in the frontpanel toolbar: 
If the milling tool bar does not show please find it in menu View/Toolbars/Frontpanel toolbar visible
In the database find the bolts named CHC (= bolts) or CSS (= bushings).
