The Simpson Strong-Tie Outdoor Accents Button-Head Connector Screw brings a low-profile, bolt-like aesthetic to exterior structural connections, making it a standout choice for pergolas, patio covers, decks, and other outdoor wood projects. Engineered specifically for use with the Outdoor Accents Mission Collection and Avant Collection connectors - as well as Essentials heavy joist hangers - this screw delivers a tested, code-listed, load-rated fastening solution that combines structural reliability with a clean, finished appearance. The black double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it well-suited for exterior and preservative-treated wood applications where long-term weather performance matters.

Key Features

• Low-profile button head with unique underhead geometry - designed, tested, and load-rated specifically for Outdoor Accents Mission Collection and Avant Collection connectors and Essentials heavy joist hangers, ensuring a structurally approved connection every time
• Engineered alternative to the Outdoor Accents structural wood screw and hex-head washer combo - delivers the same approved fastening performance in a single-fastener solution that resembles a bolted connection
• SawTooth point - drives fast and clean through wood without predrilling, saving time and reducing effort on the job
• Black double-barrier coating - provides corrosion resistance equivalent to hot-dip galvanization, making this screw suitable for certain exterior and preservative-treated wood applications as described in the evaluation report
• Deep 6-lobe T40 recess drive - delivers easy, secure bit engagement that reduces cam-out and keeps installation consistent (T40 driver bit included)
• Shank diameter of 0.220 in. and length of 3 1/16 in. - sized and engineered to meet the load requirements of Outdoor Accents hardware connections
• Head diameter of 0.760 in. - wide enough to seat cleanly within the connector geometry while maintaining the low-profile look
• Thread length of 2 3/4 in. - provides deep wood thread engagement for strong, reliable holding power in structural outdoor assemblies
