A complete line of innovative, building code-approved structural wood screws that outperform the competition.



The patented screw design offers features that are unmatched in the category and set a new benchmark for performance.

Our structural screws are ideal for a variety of projects both indoors and outdoors. The proprietary corrosion resistant coating is compliant with ACQ and other forms of treated lumber. Unlike competitor structural fasteners, the Power Pro® Structural Lag Screw features an innovative thread design and a self-drilling tip to penetrate and sink into wood quickly, resulting in a 30% faster installation, and no pre-drilling. Drive more screws per battery charge. Easy-to-read depth code imprinted on the head allows for quick post-inspection.
