Construction Lag Screws are perfect for your next outdoor project. Common applications include decks, stairs and playsets. These products have features that are both impressive and unique. Topping the list is the new "Star Drive" technology which virtually eliminates cam-out for a smooth, effortless drive every time. Chances for splitting wood are greatly reduced by the patented cross-cut threads and the wood biting cut point. These two features combine to prevent wood splitting by grinding wood and removing fibers from the hole. Use with treated lumber.
