Simpson Strong-Tie SDWS221000DBBR50 TIMBER Screw (Exterior Grade) — 0.220" x 10" T40, Black (50-Qty)
The Simpson Strong-Tie® Strong-Drive® SDWS™ Timber screw is designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. This screw is ideal for the contractor and do-it-yourselfer alike. It is code listed in IAPMO UES ER-192 and meets IRC® and IBC® code requirements for most common wood framing applications. The double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for certain exterior and preservative-treated wood applications, as described in the evaluation report.
