FOR FAST INSTALLATION
Use a 0-1800 RPM variable speed drill (at least 14.4V if cordless). Use the PoziSquare
driver bits provided. Install fastener perpendicular to deck, increasing drill speed as the
screw threads into the deck. Slightly countersink. Do not overdrive. If cam-out occurs,
remove and replace screw.
No Predrilling
GuardDog’s sharp piercing point allows for installation without predrilling for most
applications. Predrilling is recommended at all seam joints, when fastening within 1

eliminates cam-out during installation. (If cam-out does occur during installation, the
fastener should be removed and replaced with a new GuardDog screw.)
