T40 Torx drive Wafer head Construction lag screws

Great screws for barns, pole buildings, sheds, wood fences, docks, airplane hangers, and much more! With a large head and shank these wood screws are super heavy duty. And the self-drilling tip allows you to apply less torque and still drive these huge lags home. The big modified truss style round washer head helps to draw the material being fastened snuggly into place with less effort than then one would expect. The star drive torx heads allow you to drive this lag screw with much less downward pressure than otherwise would be needed
