Simpson 0.220 x 5-1/2" Black Outdoor Accents Structural Wood Screw by Simpson is a heavy-duty fastener engineered for wood-to-wood connections in outdoor structures, decks, ledgers, and decorative DIY projects. Featuring a bold thread design and SawTooth point, this structural wood screw drives easily without predrilling, saving installation time while delivering a secure, load-bearing hold. The striking black Double-Barrier Coating pairs function with appearance - giving any outdoor project a bold, finished look while providing protection against the elements. When paired with the load-rated Outdoor Accents hex-head washer, this screw creates the decorative appearance of a bolt connection with a fraction of the installation effort, making it a strong choice for both the Mission Collection and Avant Collection as well as standalone outdoor builds.

Key Features

• SawTooth Point - cuts into wood fibers cleanly to drive without predrilling, reducing installation time and labor on ledger attachments and structural connections
• Double-Barrier Coating in Black - delivers corrosion resistance alongside a bold, decorative black finish that gives outdoor wood projects a polished, bolt-like appearance
• T40 6-Lobe Drive Type - provides superior torque transfer with reduced cam-out compared to standard hex or Phillips drives, giving installers better control during high-torque fastening
• Low Profile Head (0.760 in. diameter) - sits close to the wood surface for a cleaner finished look without sacrificing holding strength in structural applications
• 5-1/2 in. Length with 3 in. Thread Length - provides deep thread engagement into the receiving member, enabling strong, lasting connections in ledger boards and heavy timber assemblies
• 0.220 in. Shank Diameter with 5 TPI bold thread - coarse thread pattern bites aggressively into wood for superior withdrawal resistance in demanding outdoor structural uses
• Compatible with Outdoor Accents Mission and Avant Collections - integrates seamlessly with load-rated decorative hardware so your structural connection also serves as a design element

Frequently Asked Questions

Does this screw require predrilling before installation?

No. The SawTooth point is specifically designed to cut into wood and drive without predrilling, reducing installation steps and saving time on structural connections like ledger attachments and post assemblies.

What drive bit is needed for this screw?

This screw uses a T40 6-Lobe drive. Using the correct T40 6-lobe bit is important for achieving full torque transfer and avoiding damage to the screw head during installation.

Can this screw be used on its own, or does it require Outdoor Accents hardware?

This structural wood screw can be used separately to add flair to any outdoor project, or in combination with the Outdoor Accents Mission Collection or Avant Collection hardware. When paired with the load-rated Outdoor Accents hex-head washer, it creates the decorative appearance of a bolt connection with simpler installation.

What type of drill is recommended for driving this screw?

For best results, use a minimum of 1/2-in. low-speed corded drill to install. A low-speed drill provides the torque needed to drive the 0.220 in. shank diameter screw into wood without overdriving or stripping the 6-lobe head.
