The Simpson Strong-Tie CCQ84SDS2.5 is an 8x beam by 4x post column cap 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 to distribute the load from the beam and provide support for the connection. Fastened with included Strong-Drive SDS Heavy-Duty Connector screws, this column cap offers fast installation while attaching to a greater net section area of the column than a standard bolt attachment normally entails. Manufactured in the United States, the CCQ84SDS2.5 is a trusted solution for demanding structural applications where performance under earthquake and wind loading is critical.

Key Features

• Low-Profile Fastening: The SDS screws provide a lower profile than standard through bolts, resulting in a cleaner, less obtrusive connection.
• Certified Welds: Certified welds provide confidence in strength and loading for every connection.
• Enhanced Uplift Performance: Uplift loads have been increased for earthquake or wind loading, making this cap suitable for high-demand structural environments.
• Diamond Holes: Diamond holes allow for temporary fastening during installation, simplifying the assembly process.
• Extended Bearing Surface: The seat extends beyond each side of the column to distribute beam loads more effectively across the connection.
• SDS Screw Compatibility: Designed specifically for use with Strong-Drive SDS Heavy-Duty Connector screws for optimal load performance. Note: Lag screws will not achieve the same load.

Specifications

• Model Number: CCQ84SDS2.5
• Size: 8x Beam, 4x Post
• Thickness: 3 Gauge
• Finish: Gray Paint
• Country of Origin: United States

Approved Applications

• Wood column-to-beam structural connections in residential and commercial construction
• Applications requiring enhanced uplift resistance under earthquake or wind loading
• Connections where a low-profile fastener is preferred over standard through bolts
• Field installations requiring temporary fastening during assembly

Installation

Install with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. Lag screws will not achieve the same load.

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

Frequently Asked Questions

What size beam and post is the CCQ84SDS2.5 designed for?

The CCQ84SDS2.5 is designed to connect an 8x beam to a 4x post, making it specifically sized for that beam-to-column configuration in wood construction.

What fasteners are used with this column cap, and are they included?

This column cap is designed specifically for use with Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws attach to a greater net section area of the column compared to standard bolt attachment.

What advantages does this cap offer over a standard bolt-attached column cap?

The SDS screws provide a lower profile than standard through bolts, resulting in a cleaner, less obtrusive connection. Additionally, the screws attach to a greater net section area of the column than standard bolt attachment, and uplift loads have been increased to meet the demands of earthquake or wind loading applications.

What features help simplify installation of the CCQ84SDS2.5?

The cap includes diamond holes that allow for temporary fastening during installation, simplifying the assembly process. The extended seat bearing surface also helps stabilize the connection by distributing beam loads beyond each side of the column during and after installation.
