Made from heat-treated carbon steel, SDS wood screws have a double-barrier coating finish that provides improved corrosion resistance over the hot-dip galvanization, making one screw versatile enough to be used on the interior, exterior and on certain pressure-treated wood applications.

The prep work required for wood screws is generally seen as a time-consuming downside, as not only is a pilot hole required but also a counterbore hole and a countersink hole.

However, Simpson Strong-Drive wood screws are 1/4" diameter structural wood screws that require no pre-drilling and are ideal for various connector installations as well as wood-to-wood applications.

The Simpson Strong-Tie patented 4CUT tip features a square core and aggressive, serrated threads. This reduces installation torque and makes driving easier while minimizing wood splitting. Many woodworkers opt to coat the screw in bar soap or beeswax prior to driving in order to ease driving and prevent screw breakage, but this may not be necessary with the patented technology of the Simpson Strong-Tie SDS wood screws.
