FastenMaster® ThruLokTM Screw Bolt Fastening System can be used for applications including multi-ply beams, deck posts, carrying beams and more. It combines the strength of a through-bolted connection with the speed of a LOK fastener with no predrilling required. Its three-part assembly includes a screw, featuring the patent-pending Paddle PointTM, engineered washer and LOK-Nut.
Save time, money and labor costs! ThruLokTM is the first fastener engineered to make a code compliant connection for your 4x4 decking posts and notched carrying beams without pre-drilling! ThruLokTM is over 15 times faster than the traditional method of installing posts and the only tool required is an 18 Volt drill. No need to predrill, hammer in a 1/2" carriage or through-bolt, and hand wrench the nut to tighten on the back. ThruLokTM zips right in and has a patent-pending encapsulating nut that self tightens on the end saving time and labor.

Installation:
- Put the ThruLokTM-Washer on the ThruLokTM 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 ThruLokTM 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 ThruLokTM-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 ThruLokTM until the pre-installed washer and hex head are almost flush against the wood surface. On the opposite side, thread the ThruLokTM nut onto the exposed point of the fastener and firmly hand tighten. Finish by driving the screw until washer and nut are snug.
WASHING INSTRUCTIONS:
Machine wash separately in cold water on a gentle cycle. Tumble dry separately on low heat. Add QE Home Wool Dryer Balls to reduce wrinkles and increases drying efficiency. Touch up with a low heat iron as needed. Do not bleach or dry clean.
