The Simpson CCQ64SDS2.5 Column Cap from Simpson Strong-Tie is engineered to deliver a strong, high-capacity connection between a 6x beam and a 4x post in wood construction. Part of the CCQ series, this column cap generally eliminates the need for additional brackets or braces, streamlining structural connections across a wide range of wood-frame applications. The seat of the column cap provides an extended bearing surface area beyond each side of the column, helping to distribute load from the beam and provide robust support for the connection. Fabricated from 7-gauge steel with a Simpson Strong-Tie gray paint finish, this cap uses Strong-Drive SDS Heavy-Duty Connector screws - included in the box - which attach to a greater net section area of the column than a bolt attachment normally entails, while delivering a lower-profile installation.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - (30) 1/4 in. x 2-1/2 in. SDS screws come with the cap so the connection is ready to install without sourcing separate fasteners
• Lower-profile fastener design - SDS screws sit below the surface profile of standard through bolts, resulting in a cleaner, less obtrusive installation in finished or visible structural assemblies
• Extended bearing seat - the seat surface area reaches beyond each side of the column, distributing beam loads more broadly and providing stronger, more reliable support at the connection point
• Certified welds - weld quality is independently certified, giving builders and inspectors confidence in the structural integrity and load ratings of every unit
• Increased uplift load capacity - uplift loads have been increased to meet the demands of earthquake or high wind loading, making this cap well suited for seismic zones and hurricane-prone regions
• Diamond holes for temporary fastening - built-in diamond holes let installers secure the cap in position before final fastening, reducing the chance of misalignment and speeding up the installation process
• 7-gauge steel construction - heavy-gauge steel provides the thickness and rigidity required for high-capacity column-to-beam connections in structural wood framing
• Simpson Strong-Tie gray paint finish - the factory-applied coating provides a consistent, professional appearance and baseline surface protection throughout the installation process

Why This Product

• Everything needed for installation is included - the (30) Strong-Drive SDS Heavy-Duty Connector screws ship with the column cap, so there is no need to track down compatible fasteners separately, saving time on the job site
• Engineered for demanding structural loads - with certified welds and increased uplift load ratings, this column cap is specifically built to handle the forces generated by earthquake and high wind events, not just standard gravity loads
• Simplifies connections without extra hardware - the CCQ series is designed to generally eliminate the need for additional brackets or braces, reducing the number of components required to complete a structurally sound column-to-beam connection
• Precision fit for 6x beam and 4x post assemblies - purpose-sized for this specific member combination, the cap delivers a consistent, well-fitted connection that supports both correct load transfer and a clean structural appearance
