Starborn® Structural H23 screws are specifically designed to attach deck ledgers to rim joists. They are fully tested and code compliant alternatives to traditional lag screws and through-bolts, with no pre-drilling required. Structural H23 screws feature a hex washer head for maximum drivability, a unique Tri-Forge® point for reduced driving torque, and a high-adhesion exterior grade coating. Complete fastening instructions are available in the Deck Ledger to Rim Joist Technical Guide. Structural H23 screws can also be used in a variety of other code compliant wood-to-wood connections.
