Product Description
The Simpson CCQ5-4SDS2.5 CCQ Column Cap from Simpson Strong-Tie provides a strong, engineered column-to-beam connection for wood construction projects where a 5-1/8 in. beam meets a 4x post. The extended seat design delivers additional bearing surface area beyond each side of the column, helping distribute load from the beam and reinforce the overall connection - generally eliminating the need for additional brackets or braces. Rather than relying on traditional through bolts, this column cap is built for use with Strong-Drive SDS Heavy-Duty Connector screws, which attach to a greater net section area of the column for a more efficient and faster installation. Fabricated from 3-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, the CCQ5-4SDS2.5 is well-suited for structural applications where verified strength and dependable load transfer are required.
Key Features
- Strong-Drive SDS Heavy-Duty Connector screws included - eliminates the need to source fasteners separately and allows for faster installation compared to traditional bolt methods
- Lower-profile fastener design vs. standard through bolts - results in a cleaner, less obtrusive connection that works well in finished or visible structural applications
- Extended seat with additional bearing surface area beyond each side of the column - helps distribute beam load more effectively across the connection, reducing stress concentration at the post
- Certified welds - provides verified confidence in the strength and load-carrying integrity of the cap without relying on field assumptions
- Increased uplift load values for earthquake and wind loading - makes this column cap a reliable choice for structural connections in high-wind or seismic zones
- Diamond holes for temporary fastening - allows the installer to hold the cap in position during layout before final fastening, improving accuracy and reducing rework
- 3-gauge steel construction with Simpson Strong-Tie gray paint finish - delivers heavy-duty structural performance with a corrosion-resistant coating suited for wood frame construction environments
Why This Product
- All-in-one connection hardware - the column cap ships with the required Strong-Drive SDS screws already included, so contractors and builders have everything needed to complete the column-to-beam connection without sourcing additional fasteners
- Engineered to reduce installation steps - the CCQ design generally eliminates the need for additional brackets or braces at the column-beam joint, simplifying the structural assembly and saving time on the job site
- Built for demanding load conditions - uplift loads have been increased to address earthquake and high-wind scenarios, making this cap a dependable choice for residential and commercial wood frame projects in challenging climate or seismic regions
- Made in the United States with certified welds and heavy-gauge steel - the 3-gauge construction and weld certification give builders and inspectors a traceable standard of quality at a critical structural connection point

Frequently Asked Questions
- What beam and post sizes is the CCQ5-4SDS2.5 designed to fit?
- This column cap is specifically designed for a 5-1/8 in. beam width and a nominal 4x post size, making it suitable for engineered lumber and standard dimensional lumber applications in wood construction.
- What fasteners are required, and are they included?
- This column cap installs with 30 Strong-Drive SDS Heavy-Duty Connector screws measuring 1/4 in. x 2-1/2 in. (Model: SDS25212). These screws are included with the column cap, so no separate fastener purchase is needed.
- Why are SDS screws used instead of standard through bolts?
- The Strong-Drive SDS screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than a bolt attachment normally allows. This results in a cleaner installation appearance and can deliver strong connection performance throughout the assembly.
- What material and finish is used on the CCQ5-4SDS2.5?
- The column cap is fabricated from 3-gauge steel with certified welds for verified strength and load performance. It is finished in Simpson Strong-Tie gray paint to provide a consistent, durable surface coating.
