Product description

Strong-Drive SDWS TIMBER Screw (Exterior Grade) 0.220 in. x 10 in. T40, Tan (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.

EASY DRIVING: These exterior screws have a 6-lobe T40 drive that provides positive engagement, making the screw easy to drive. The Sawtooth point ensures a fast start, eliminating the need for predrilling in almost every application.
MULTIPLE APPLICATIONS: Due to the versatile nature of these screws, they can be successfully used in a variety of applications from wood-to-wood ledger applications, mass timber connections including CLT wall-to-wall, floor-to-floor and lap joints.
DOUBLE BARRIER COATING: Each of these timber screws have double-barrier coating, which provides corrosion resistance that is equivalent to hot-dip galvanization in steel screws, making it suitable for select exterior and preservative-treated wood applications.
CONVENIENT DESIGN: As they are intended to serve as an alternative to through bolting and traditional lag bolts, these screws are distinguished by the bold thread design, and the under head nibs allow for the head to drive flush to surface with reduced splintering.
