Simpson Outdoor Accents Structural Wood Screw - 0.250 x 2 inch, Black Double-Barrier Coating by Simpson Strong-Tie is engineered for outdoor structural connections that demand both strength and visual appeal. This low-profile black structural screw drives fast without predrilling, saving installation time on decks, pergolas, fences, and other exterior wood projects. Compatible with nominal 2x lumber, it pairs with the patented, load-rated Outdoor Accents hex-head washer to deliver the bold, finished look of a bolt connection with the speed and simplicity of a screw. The Type-17 point and T40 6-Lobe drive work together to reduce cam-out and splitting, making this a reliable choice for both professional contractors and serious DIY builders working with pressure-treated or outdoor lumber.

Key Features

• No Predrilling Required - the Type-17 point bores its own pilot path as it drives, cutting installation time significantly on outdoor framing and finish work
• Double-Barrier Coating in Black - provides corrosion resistance suited for outdoor environments while delivering the dark, decorative finish that complements the Outdoor Accents connector system
• Low Profile Head (0.760 in. diameter) - sits close to the wood surface for a clean, finished appearance that mimics a bolt connection without the bulk
• T40 6-Lobe Drive - maximizes torque transfer and reduces cam-out during high-torque driving, ensuring secure, consistent seating in dense lumber
• Type-17 Point - self-starting tip bites into wood fibers immediately, reducing the chance of splitting even in hard or dense outdoor lumber species
• 0.250 in. Shank Diameter with 10 TPI Threading - provides robust holding power in structural wood-to-wood connections, suitable for nominal 2x lumber applications
• 1-1/4 in. Thread Length - engineered thread engagement optimized for the 2 in. overall length, maximizing withdrawal resistance in the receiving member
• Made in the United States - domestic manufacturing supports consistent quality control for structural fastener applications

Why This Product

• Eliminates the predrilling step that slows down outdoor structural projects - the Type-17 self-starting point means you drive directly into nominal 2x lumber and move on, reducing labor time on decks, pergolas, and exterior framing
• Delivers a decorative bolt-like appearance when paired with the load-rated Outdoor Accents hex-head washer - ideal for builders and homeowners who want structural integrity without sacrificing the finished aesthetic of their outdoor space
• Versatile compatibility with both the Mission Collection and Avant Collection, as well as standalone use - one screw works across multiple outdoor accent connector systems, simplifying purchasing and jobsite inventory
• The black Double-Barrier Coating coordinates with Outdoor Accents hardware finishes, making this screw the correct match for a cohesive, professional-looking outdoor structure rather than an afterthought fastener

Frequently Asked Questions

Do I need to predrill before installing this structural wood screw?

No. The Type-17 point is specifically designed to start and drive without predrilling, which reduces installation time. This makes it especially practical for projects involving nominal 2x lumber where drilling a pilot hole first would slow down the workflow.

What drive bit does this screw require, and is one included?

This screw uses a T40 6-Lobe drive. A T40 drive bit is included with the product, so you can begin installation right away without sourcing a separate bit. Using the correct T40 bit is important for maximizing torque and minimizing cam-out.

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

This structural wood screw can be used with either the Mission Collection or Avant Collection connectors, or separately to add flair to any outdoor project. It does not require an Outdoor Accents connector to function, though pairing it with the load-rated Outdoor Accents hex-head washer delivers the decorative bolt-connection appearance the system is known for.

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 corded drill provides the consistent torque needed to seat the 0.250-in. shank cleanly into structural lumber without overdriving or stripping the T40 6-Lobe drive recess.
