APPLICATION
Starborn® Structural F23 screws are designed for heavy duty framing applications including decking, fencing, pergolas, landscape timbers, timber framing, and more. They are fully tested and code compliant alternatives to traditional lag screws and through-bolts, with no pre-drilling required. These versatile screws feature a low-profile flat head design that minimizes interference with connectors and finish materials, a unique Tri-Forge® point for reduced driving torque, and a high-adhesion exterior grade coating. The 4″ and 5″ lengths are specifically designed for code compliant deck ledger attachments.
