The Simpson CCQ46-SDS2.5HDG CCQ HDG Column Cap for 4x Beam, 6x Post with Strong-Drive SDS Screws is engineered by Simpson to deliver strong, reliable column-to-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 providing critical support for the connection - generally eliminating the need for additional brackets or braces. Built from 7-gauge steel with a hot-dip galvanized finish, this heavy-duty post cap is well suited for demanding exterior and treated-wood applications where both structural integrity and corrosion resistance are essential.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - installation is faster and cleaner, and the screws attach to a greater net section area of the column than a bolt attachment normally entails, resulting in a stronger connection
• Lower-profile SDS screw fastening - delivers a neater, less obtrusive finished appearance compared to standard through bolts
• Certified welds throughout - provides verifiable confidence in the strength and load capacity of every connection
• Increased uplift load ratings - the column cap is engineered to handle elevated uplift demands, making it a dependable choice for high-wind and seismic applications
• Diamond holes for temporary fastening - simplifies positioning and alignment during installation, reducing time on the job
• 7-gauge steel construction - delivers the thickness and rigidity needed for structural post-to-beam connections in demanding wood-frame builds
• Hot-dip galvanized finish - offers extra corrosion resistance for exterior environments and contact with pressure-treated lumber, extending the service life of the connection

Why This Product

• A complete fastening solution right out of the box - the column cap ships with (30) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws already included, so there is no need to source compatible hardware separately before starting the job
• Engineered for the realities of exterior and treated-wood construction - the hot-dip galvanized coating provides the level of corrosion resistance required where standard coatings fall short, including applications involving treated lumber and exposed outdoor conditions
• Designed for code-sensitive structural applications - certified welds and increased uplift load ratings make this column cap a credible choice for projects where earthquake or wind loading must be accounted for in the connection design
• Versatile bearing design that supports the whole connection - the extended seat bearing surface distributes load from the beam across a wider area, reducing stress concentration at the post and supporting a more balanced, stable column-to-beam assembly

Frequently Asked Questions

What fasteners are required to install the CCQ46-SDS2.5HDG, and are they included?

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

Why are SDS screws used instead of standard through bolts?

The Strong-Drive SDS Heavy-Duty Connector 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 this column cap suitable for exterior or treated-wood applications?

Yes. The hot-dip galvanization (HDG) finish provides extra corrosion resistance, making this column cap well suited for exterior and treated-wood applications.

Can the CCQ46-SDS2.5HDG be used in high-wind or seismic conditions?

Yes. Uplift loads have been increased for earthquake or wind loading, and the certified welds provide confidence in strength and loading performance for demanding structural conditions.
