FastenMaster FMTHR614-INDY Lag Screw ThruLOK 1/2" X 6-1/4" L Hex Galvanized Steel Galvanized

ThruLOK is a multi-purpose structural wood-to-wood fastener that replaces carriage or through bolts. It is perfect for specific applications such as multiple beams, girder trusses, deck posts and many places where a traditional carriage or through-bolt is used. The performance and corrosion resistance of ThruLOK is guaranteed for the life of the project when used in accordance with the installation instructions and supporting technical literature included in all packaging. ThruLOK is tested and supported by engineering data that conforms to the most current ICC standards. It is also approved for use in ACQ or treated lumber. The ThruLOK system combines the strength of a through-bolted connection with the speed of a LOK fastener with no predrilling required. It can be used for applications including multi-ply beams, deck posts, carrying beams and more.
