LumberLok Structural Wood Screws

The LumberLok Structural Connector Screw is a self-drilling screw that can be used with a number of USP Structural Connectors and also for wood-to-wood applications. The screws feature a T20 Torx® head with integral washer and gimlet point for ease of installation. The twin-lead threads drive in twice as fast as the single lead threads significantly reducing installation time. The USP head stamp identifies the screw length for easy inspection. Screw shear capacities are based on a diameter of 0.162" when the shear plane is on the screw shank (SH) and 0.109" when the shear plane is on the threads (T). USP LumberLok Structural Connector Screws have a bending yield strength of 180,000 psi.
