The Simpson CC86 Column Cap is a heavy-duty structural connector engineered to create strong, reliable column-to-beam connections in wood-frame construction. Sized for a nominal 8x beam width and a nominal 6x post size, this connector features a seat design that extends bearing surface area beyond each side of the column, helping to distribute load from the beam and provide solid support at the connection point. Fabricated from 3-gauge steel with a Simpson Strong-Tie gray paint finish and certified welds throughout, the CC86 is built to meet the demands of both residential and commercial structural applications - including those in high-wind and seismic regions.

Key Features

• Certified welds - provide verified strength and load confidence, so you know the connection meets structural expectations before installation is complete
• Increased uplift load capacity - engineered to handle elevated forces from earthquake or wind loading, making this connector appropriate for high-demand structural environments
• NDS code-compliant bolt spacing - ensures the connection meets National Design Specification requirements, reducing the risk of code issues on inspected projects
• Diamond holes for temporary fastening - allow the connector to be held in position during layout and alignment before final bolting, simplifying the installation process
• 3-gauge steel construction - delivers the structural thickness required for heavy column-to-beam connections where load transfer and long-term durability matter
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and baseline surface protection suited to typical wood construction environments
• Installs with six 3/4-in. diameter bolts - a defined fastener requirement that takes the guesswork out of hardware selection and supports consistent, repeatable installation

Why This Product

• Built for seismic and wind-load applications - the CC86 specifically addresses increased uplift resistance, making it a practical choice for structural connections in earthquake zones and high-wind regions where standard connectors may fall short
• Certified weld quality you can count on - unlike connectors with uncertified fabrication, the CC86 carries certified welds that give engineers, inspectors, and contractors documented confidence in the strength of every connection
• Seat design that improves load distribution - the extended bearing surface on each side of the column helps transfer beam loads more evenly into the post, reducing stress concentrations at the connection point
• Sized for demanding structural members - matching a nominal 8x beam to a nominal 6x post, this column cap is purpose-built for the larger timber sizes common in heavy wood-frame structures, pergolas, pavilions, and post-and-beam construction
