Important Installation Instructions If the screws are to be driven by a screw gun, be sure the bit is securely seated in the square recess of the screw. Start slowly and gradually increase speed until the head is driven flush. Using a high driving speed increases the chance of stripping the square drive recess. If the tool has an adjustable torque collar, use a piece of scrap lumber to determine the proper setting needed to drive the head flush with the surface. This will prevent twisting off the screw head.
