.275" x 4-1/2" Conquest Structural Screw - T-30 Star Drive, Pkg 50

Conquest structural screws are heavy duty timber screws designed to be used in place of conventional lag bolts. All Conquest CSS screws are ICC certified under listing report ESR-4613. The high strength hardened steel allows these structural 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. Conquest Structural Timber Screws feature a silver ruspert coating that's approved for use with ACQ treated lumber. Special shank ribs enlarge the driving hole to reduce splitting, reduce driving resistance and pull the materials tighter together.
