Whether you are a homeowner or a contractor, you demand quality products to complete a project faster, easier and stronger. FastenMaster offers quality materials for a variety of projects, including composite deck screws, exterior wood screws, engineered wood fasteners, heavy-duty wood screws, ledger board fasteners, and stainless-steel trim screws.
| ThruLOK has been a great addition to the FastenMaster LOK Line of structural wood-to-wood fasteners. With a three-part assembly including a ThruLOK fastener featuring the patent-pending Paddle Point™, engineered washer, and LOK-Nut, ThruLOK offers the speed of a LOK Line Product and the strength of through-bolt connections. |  |
This fastener comes in specific lengths that allow contractors to replace their 1⁄2″ carriage and through-bolts in three primary deck applications: 6 1⁄4″ fastener – Single 2x to 4x Decking Posts, 7″ fastener – Notched 6x Carrying Beams, and 8″ fastener – Double 2x to Single 4x Decking Posts. There are no drill bits or wrenched required and installs with an 18-volt cordless drill. Moreover, their galvanized coating meets IRC ACQ corrosion requirements and there is a lifetime performance guarantee.
To install FastenMaster ThruLOK, simply put the ThruLOK-Washer on the ThruLOK screw with the teeth of the washer facing away from the head of the fastener. Using a 1⁄2″ high torque variable speed drill (18V if cordless), drive the ThruLOK until the washer and hex head are just above the wood surface (approx 1⁄4″) and the point of the screw protrudes out the other side of the connection. Thread the ThruLOK-Nut onto the point of the fastener and tighten the nut by hand until flush with the wood. Finally, tighten the screw with a drill and repeat to match a code-compliant fastening pattern.
