The Simpson CCQ5-8SDS2.5 CCQ Column Cap from Simpson Strong-Tie delivers a high-capacity column-to-beam connection purpose-built for wood construction projects. Designed to fit a 5-1/8 in. beam and a nominal 8x post, this column cap generally eliminates the need for additional brackets or braces, simplifying the connection at the column head. The extended seat bearing surface reaches beyond each side of the column, helping distribute load from the beam and provide reliable support at the connection point. Fabricated from 3-gauge steel with certified welds and a Simpson Strong-Tie gray paint finish, this column cap comes complete with 30 Strong-Drive SDS Heavy-Duty Connector screws for straightforward installation.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - faster installation out of the box with no separate fastener purchase required, and attachment to a greater net section area of the column than a bolt attachment normally entails
• Lower-profile SDS screw connection - keeps the finished assembly cleaner and less obtrusive compared to standard through bolts, which matters in exposed structural applications
• Extended seat bearing surface - distributes the load from the beam beyond each side of the column, reducing stress concentration and improving overall connection support
• Certified welds - gives builders and inspectors confidence in the structural integrity and load ratings of the connection
• Increased uplift load ratings for earthquake and wind loading - makes this column cap suitable for demanding structural applications in high-load environments
• Diamond holes for temporary fastening - allows the cap to be held in place during positioning before final fasteners are driven, streamlining the installation process
• 3-gauge steel construction with Simpson Strong-Tie gray paint finish - provides heavy-duty strength and corrosion resistance appropriate for structural column-to-beam connections

Why This Product

• An all-in-one column cap solution - the CCQ5-8SDS2.5 is designed to generally eliminate the need for additional brackets or braces in most column-to-beam connections, reducing complexity and material costs on the job site
• Built for code-sensitive structural environments - increased uplift loads for earthquake and wind loading, combined with certified welds, make this cap well-suited for projects where structural performance under lateral and uplift forces must be documented and verified
• Screws outperform lag bolts at the connection - the Strong-Drive SDS screws fasten to a greater net section area of the column than a standard bolt attachment, contributing to a stronger, more reliable structural connection without the added bulk of through bolts
• Designed for efficiency from layout through final fastening - diamond holes allow temporary positioning before committing to final fastener placement, and the included SDS screws mean crews can move from layout to installation without interruption
