Simpson CCQ66SDS2.5 CCQ Column Cap for 6x Beam, 6x Post with Strong-Drive SDS Screws by Simpson Strong-Tie is engineered to deliver strong, reliable column-beam connections in wood construction. The seat of the column cap provides an additional surface area of bearing that extends beyond each side of the column, helping distribute the load from the beam and provide support for the connection. Designed to accommodate 6x beams and 6x posts, this column cap uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation and attaches to a greater net section area of the column than a bolt attachment normally entails - all while generally eliminating the need for additional brackets or braces.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - installs faster than traditional bolt methods and engages a greater net section area of the column for a stronger, more reliable connection
• Lower profile than standard through bolts - results in a cleaner, less obtrusive finished appearance without sacrificing connection strength
• Certified welds - provides verified confidence in the strength and load capacity of every connector
• Increased uplift load ratings for earthquake or wind loading - makes this column cap a dependable choice for structural projects in high-wind or seismic design regions
• Extended bearing seat surface - distributes load from the beam across a wider area beyond each side of the column, improving overall support at the connection point
• Diamond holes for temporary fastening - simplifies positioning and alignment during installation before final fasteners are driven
• 7-gauge steel construction with Simpson Strong-Tie gray paint finish - delivers heavy-duty structural integrity with a corrosion-resistant coating suited for wood post and beam applications

Why This Product

• Engineered for a broader net section attachment - the SDS screw fastening method connects to more of the column's material than standard bolt attachments, meaning the structural connection works harder where it matters most in post-and-beam framing
• Built for demanding load conditions - with uplift loads increased specifically for earthquake or wind loading, this column cap is a practical solution for contractors and builders working in regions with strict structural design requirements
• Simplified installation without sacrificing performance - the included Strong-Drive SDS screws drive quickly and sit at a lower profile than through bolts, reducing installation time and keeping the connection area clean and unobstructed
• Designed to stand alone - the extended bearing seat and certified welds are engineered to generally eliminate the need for additional brackets or braces, reducing material costs and simplifying the overall connection assembly

Frequently Asked Questions

What fasteners are used to install the CCQ66SDS2.5?

Install with (30) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212 included). Note that lag screws will not achieve the same load.

Why use SDS screws instead of standard through bolts?

The 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, resulting in a stronger and cleaner connection.

Is the CCQ66SDS2.5 suitable for use in high-wind or seismic regions?

Yes. Uplift loads have been increased for earthquake or wind loading, making this column cap well-suited for projects in areas subject to high-wind or seismic design requirements.

Can the CCQ column cap be ordered without legs for field-welding to pipe or other columns?

Yes. The CCOQ and ECCOQ column cap only (no straps) versions may be ordered for field-welding to pipe or other columns. Dimensions are the same as the CCQ and ECCQ.
