Installation:

• Put the ThruLok™-Washer on the ThruLok™ screw with the teeth of the washer facing away from the head of the fastener. No predrilling required when properly installed. Using a 1/2" high torque variable speed drill (18V if cordless), drive the ThruLok™ until washer and hex head are just above the wood surface (approx 1/4") and point of screw protrudes out other side of connection. Thread the ThruLok™-Nut onto point of fastener. Hand tighten nut until flush with wood. Tighten screw with drill. Repeat to match code-compliant fastening pattern.
• Using an Impact driver or high torque 1/2" variable speed drill (18V if cordless), drive the ThruLok™ until the pre-installed washer and hex head are almost flush against the wood surface. On the opposite side, thread the ThruLok™ nut onto the exposed point of the fastener and firmly hand tighten. Finish by driving the screw until washer and nut are snug.
