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.
- SawTooth point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
- Bold thread design provides superior holding power

- Large low-profile washer head provides maximum bearing area (0.760-in. head dia.)
- Size identification on all SDWS screw heads
- 6-lobe T40 drive provides positive engagement that makes the screw easy to drive and improves bit life (replacement driver bit – BIT40T-134-R2)
- Length: 5 in.
- Color: tan
- Quantity: 50 per package
- SDWS screws install best with a low-speed 1/2-in. drill and 6-lobe, T40 driver bit (included)
