STAR CON LAG 5/16X8

These construction lag screws feature Star Drive technology which virtually eliminates camout 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. The 1000 hour bronze ceramic coat provides superior rust and corrosion protection.
