FastenMaster ThruLok Screw Bolt

The ThruLOK-? 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 pre-drilling required. ThruLOKs replace traditional carriage and through bolts in applications ranging from 4-1/2 to 8-1/2 in. Its three-part assembly includes a screw, featuring the patent pending Paddle PointG?ó, engineered washer and LOK-Nut.
