The Simpson Strong-Tie CCQ4.62-5.50SDS Column Cap is an engineered heavy-duty connector built to create strong, reliable column-to-beam connections between a triple 2x beam and a 6x post in wood construction. The extended seat design provides additional bearing surface area beyond each side of the column, helping distribute loads from the beam more effectively across the connection. Rather than relying on traditional through-bolt attachment, this column cap uses Strong-Drive SDS Heavy-Duty Connector screws to engage a greater net section area of the column - delivering a faster installation process and a lower-profile result. Thirty 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws are included, making this a complete connection solution ready for structural applications where enhanced uplift resistance against earthquake or wind loading is required.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws instead of through bolts - engage a greater net section area of the column for a stronger connection while keeping a lower profile at the joint
• Extended seat with additional bearing surface area - distributes beam loads beyond each side of the column, improving load transfer and supporting the overall connection
• Increased uplift load capacity for earthquake and wind loading - engineered to meet the demands of high-load environments, providing greater confidence in seismic and high-wind applications
• Certified welds - third-party verified for strength and loading performance, giving builders and inspectors confidence in the structural integrity of each connector
• Diamond holes for temporary fastening - allow the cap to be held in position during layout and alignment before final installation, improving accuracy and workflow on the job site
• 7-gauge steel construction - heavy-duty material thickness delivers the load capacity and durability required for structural column-cap applications
• Simpson Strong-Tie gray paint finish - provides a consistent, professional appearance and baseline corrosion resistance for interior and protected structural applications
• Includes 30 Strong-Drive SDS screws - everything needed for a complete installation arrives together, eliminating a separate fastener purchase and reducing project delays

Why This Product

• A complete, ready-to-install connection - the included Strong-Drive SDS Heavy-Duty Connector screws mean no separate fastener sourcing is required; the cap and its full screw complement arrive together for a streamlined installation process
• Eliminates the need for additional brackets or braces - the CCQ series is specifically designed to handle column-to-beam connections without supplemental hardware, simplifying the build and reducing material cost
• Built for demanding structural environments - uplift loads have been increased specifically for earthquake and wind loading, making this column cap a dependable choice for projects in high-load or code-sensitive regions
• Faster installation without sacrificing connection strength - SDS screw attachment is quicker than traditional bolt drilling while connecting to a greater net section area of the column, delivering both job-site efficiency and structural performance

Frequently Asked Questions

What beam and post sizes is the CCQ4.62-5.50SDS designed to fit?

This column cap is specifically designed for use with a triple 2x beam and a 6x nominal post. The beam width accommodated is 4-1/2 in., making it the correct fit for a triple 2x lumber beam assembly on a 6x post.

What fasteners are required for installation, and are they included?

Installation requires 30 Simpson Strong-Drive SDS Heavy-Duty Connector screws sized 1/4 in. x 2-1/2 in. (Model: SDS25212). These screws are included with the column cap, so no separate fastener purchase is necessary.

Why are SDS screws used instead of standard through bolts?

Strong-Drive SDS screws provide a lower profile than standard through bolts, resulting in a cleaner installation. They also attach to a greater net section area of the column compared to a typical bolt attachment, which contributes to a stronger connection and increased uplift capacity for earthquake or high-wind loading conditions.

What material and finish is used on this column cap?

The CCQ4.62-5.50SDS is constructed from heavy 7-gauge steel with certified welds and is finished with a Simpson Strong-Tie gray paint coating.
