Conquest structural screws are heavy duty timber screws designed to be used in place of conventional lag bolts. The high strength hardened steel allows these timber screws to be a smaller diameter than lag bolts yet have the same strength. A type 17 point combined with serrated starting threads make for quick installation and eliminates the tedious process of pre-drilling. The T-30 star drive provides excellent driving power without worry of stripping the head due to cam out.
