| 1)Insert the 8 or 10 mm (according to required size) hex head adapter into the drill motor. Center the adapter into the drill's chuck to ensure that adaptor does not wander. | |
| 2)Put on the safety glasses to protect your eyes. | |
| 3)Inspect the hex end of the adaptor for cleanliness. If metal shavings are built up inside the tip, insert the drilling end of the screw into the cavity of the hex head while holding the trigger of the drill. | |
| 4)Place a self-drilling screw into the hex head adapter. | |
| 5)Depress the trigger of the drill slowly, while the drilling tip of the screw rests against the metal. Increase the speed of the drill when the screw finds its center. | |
| 6)Stop drilling when the head of the self drilling screw tightens against the surface of the metal. If the drill you are using does not have a clutch, pay close attention to the screw head, as too much pressure will either snap the screw of strip the threads formed in the metal by the screw. | |
| 7)Perform Step 3 before you install another self drilling screw. |
