Product Description
The Simpson CCQ5-4HDG-SDS CCQ HDG Column Cap for 5-1/8 in. Beam, 4x Post with Strong-Drive SDS Screws is a heavy-duty structural connector engineered by Simpson to deliver strong, reliable column-beam connections in wood construction. The seat of the column cap provides an additional bearing surface that extends beyond each side of the column, helping distribute the load from the beam and provide critical support at the connection point. Built from 3-gauge steel with a hot-dip galvanized finish, this column cap is well suited for demanding exterior installations and treated-wood applications where long-term corrosion resistance is essential. Thirty 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws are included, so the hardware needed for installation arrives with the cap.
Key Features
- Strong-Drive SDS Heavy-Duty Connector screws included - eliminates a separate hardware purchase and allows installation to begin immediately with the correct fasteners already on hand.
- SDS screws provide a lower profile than standard through bolts - keeps the connection clean and compact while attaching to a greater net section area of the column than a bolt attachment normally entails.
- Extended seat bearing surface beyond each side of the column - distributes the beam load more effectively across the connection, supporting a stronger and more stable post-to-beam joint.
- Certified welds - gives buyers confidence in the structural integrity and load-carrying capacity of the connector before it ever goes into the field.
- Uplift loads increased for earthquake or wind loading - makes this column cap a dependable choice for projects in high-wind or seismic zones where enhanced uplift resistance is required.
- Diamond holes for temporary fastening - simplifies alignment and staging during installation, allowing the connector to be held in position before final fastening.
- Made from 3-gauge steel - heavy material thickness translates to the structural strength needed for demanding load-bearing post and beam applications.
- Hot-dip galvanized coating - provides extra corrosion resistance compared to standard finishes, making this column cap a dependable option for exterior structures and connections involving treated lumber.
Why This Product
- A purpose-built connector that generally eliminates the need for additional brackets or braces - Simpson designed the CCQ column cap to handle column-beam connections on its own, reducing the number of components required and simplifying the overall structural assembly.
- Fastener-inclusive design saves time and reduces risk of mismatched hardware - the included Strong-Drive SDS screws are the correct fasteners for this specific cap, ensuring the connection is made with hardware that meets the load ratings for the product rather than a substitute that may not.
- Hot-dip galvanization makes it a lasting choice for exterior and treated-wood projects - where standard coatings can break down over time in harsh or chemically active environments, the HDG finish on this column cap is engineered to hold up, protecting the structural connection for the long term.
- Increased uplift resistance addresses real-world loading conditions - for decks, pergolas, carports, and other open structures exposed to wind or located in seismic regions, the enhanced uplift capacity built into this connector directly addresses the forces that put column-beam connections under the most stress.

Frequently Asked Questions
What size beam and post does the CCQ5-4HDG-SDS fit?
This column cap is designed for a 5-1/8 in. wide beam and a nominal 4x post, making it suitable for engineered lumber and other beams of that width paired with standard 4x column members.
Why use Strong-Drive SDS screws instead of standard through bolts?
The Strong-Drive SDS Heavy-Duty Connector screws provide a lower profile than standard through bolts and allow attachment to a greater net section area of the column than a bolt attachment normally entails, resulting in faster installation and strong, reliable connections. Note that lag screws will not achieve the same load.
Is this column cap suitable for exterior or treated-wood applications?
Yes. The hot-dip galvanization (HDG) finish offers extra corrosion resistance, making the CCQ5-4HDG-SDS well suited for exterior environments and applications involving treated wood where increased protection against corrosion is required.
Has this column cap been rated for seismic or high-wind conditions?
Yes. Uplift loads have been increased for earthquake or wind loading, and the connector features certified welds for confidence in strength and loading, providing added assurance in demanding structural applications.
