Product Description
The Simpson CCQ5-6SDS2.5 CCQ Column Cap is a heavy-duty structural connector built to create strong, reliable column-to-beam connections in wood construction. Sized for a 5-1/8 in. beam and a nominal 6x post, this cap is engineered to generally eliminate the need for additional brackets or braces, simplifying structural framing on decks, pergolas, post-frame buildings, and similar projects. Its extended seat design increases the bearing surface area beyond each side of the column, helping distribute beam loads more effectively across the connection. Installation is driven by Strong-Drive SDS Heavy-Duty Connector screws - included - which engage a greater net section area of the column than standard through-bolt attachments, delivering a faster, lower-profile installation without sacrificing load capacity.
Key Features
- Strong-Drive SDS Heavy-Duty Connector screws included - thirty 1/4 in. x 2-1/2 in. SDS screws ship with the cap, so the connection is ready to install right out of the box with no separate hardware purchase required.
- Lower-profile fastening than standard through bolts - SDS screw installation sits tighter to the column surface, producing a cleaner finished appearance while still achieving high load ratings.
- Extended seat bearing surface - the seat projects beyond each side of the column, spreading beam load over a larger area and providing added support at the connection point.
- Certified welds - weld certification provides documented confidence in structural integrity and load-carrying capacity for inspected or permitted projects.
- Increased uplift load ratings for seismic and wind applications - enhanced uplift capacity makes this cap suitable for earthquake and high-wind load environments where standard connectors may fall short.
- Diamond holes for temporary fastening - allow the cap to be held in position during layout and alignment before final SDS screw installation, reducing the chance of misalignment.
- 3-gauge steel construction - heavy steel gauge delivers the structural thickness required for high-capacity post-to-beam connections in demanding framing applications.
- Simpson Strong-Tie gray paint finish - provides a corrosion-resistant coating suitable for the protected interior or covered exterior conditions typical of post-frame and deck framing.
Why This Product
- Complete, ready-to-install package - the cap ships with all thirty required SDS screws included, eliminating a separate trip to source fasteners and ensuring the correct hardware is always used for rated load performance.
- Faster installation with greater column engagement - Strong-Drive SDS screws attach to a greater net section area of the column than a bolt attachment normally allows, combining speed of installation with connection quality that meets structural demands.
- Built for code-sensitive seismic and wind load conditions - uplift loads have been increased specifically for earthquake and wind loading scenarios, making this cap a practical choice for projects in high-demand regions where uplift resistance is a design requirement.
- Versatile fit that reduces job-site complexity - sized to accommodate a 5-1/8 in. glulam or engineered beam on a 6x post, the CCQ generally eliminates the need for supplemental brackets or braces, streamlining the structural framing process.

Frequently Asked Questions
- What beam and post sizes is the CCQ5-6SDS2.5 compatible with?
- This column cap is designed for a 5-1/8 in. beam width and a nominal 6x post size. It is engineered specifically for these member sizes and generally eliminates the need for additional brackets or braces in wood construction applications.
- What fasteners are required, and are they included?
- The CCQ5-6SDS2.5 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 necessary.
- 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 entails. This results in a cleaner, less obtrusive connection without sacrificing structural performance.
- What material and finish is this column cap made from, and is it suitable for seismic or high-wind applications?
- The CCQ5-6SDS2.5 is made from 3-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish. Uplift loads have been increased specifically to address earthquake and wind loading requirements, making it suitable for demanding structural environments.
