Starborn Industries Structural H19 Multi-Purpose Hex Head Wood Screws feature a hex washer head for maximum drivability, a unique Tri-Forge point for reducing drive torque, and a high-adhesion exterior grade coating. These screws are IRC/IBC code compliant and are alternatives to traditional lag screws and through-bolts without the need for pre-drilling. The black exterior grade coating has high-adhesion and is an ACQ approved alternative to hot-dip galvanized coatings. The 6" screw is ideal for truss or rafter to top plate connections and is a code compliant alternative to toe-nail connections, metal hurricane ties, and seismic clips.
