The Simpson CCQ77SDS2.5 Column Cap from Simpson Strong-Tie is engineered to deliver strong, reliable column-to-beam connections in wood construction. The seat of this column cap extends beyond each side of the column, providing an additional bearing surface that helps distribute the load from the beam and enhances support at the connection point. Rather than relying on traditional through bolts, this cap uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation and attachment to a greater net section area of the column - a practical advantage in structural timber framing. Built from 3-gauge steel with a Simpson Strong-Tie gray paint finish, the CCQ77SDS2.5 is a dependable solution for timber framing projects requiring robust uplift resistance and efficient load transfer.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - eliminates the need to source fasteners separately and enables faster, cleaner installation compared to standard through-bolt methods
• Lower-profile SDS screw fastening - keeps connections cleaner and less obtrusive than traditional through bolts, which is especially valuable in exposed timber applications
• Extended bearing seat design - the seat reaches beyond each side of the column to distribute beam loads more effectively, improving structural performance at the connection
• Certified welds - provides confidence in the strength and load-carrying capacity of the assembled connection
• Increased uplift load ratings - engineered to handle elevated demands from earthquake or wind loading, making this cap suitable for projects in high-load environments
• Diamond holes for temporary fastening - allows the cap to be positioned and held in place during installation before final fastening, improving accuracy and ease of assembly
• 3-gauge steel construction with Simpson Strong-Tie gray paint finish - delivers heavy-duty structural integrity along with corrosion-resistant protection suited to demanding construction conditions

Why This Product

• Designed to simplify the connection process - Simpson Strong-Tie column caps are sized to generally eliminate the need for additional brackets or braces, reducing hardware complexity and saving time during timber framing installation
• Fasteners that work harder than bolts - the Strong-Drive SDS screws attach to a greater net section area of the column than a bolt attachment normally provides, resulting in a stronger, more efficient connection with a lower profile
• Built for demanding load conditions - with uplift loads increased for earthquake or wind loading and certified welds throughout, this cap is engineered to perform reliably in structurally critical applications
• Everything needed is included - the column cap ships with the required Strong-Drive SDS screws, so the connection can be completed without additional hardware sourcing or compatibility concerns

Frequently Asked Questions

What beam and post sizes is the CCQ77SDS2.5 designed to fit?

This column cap is designed for a 6-3/4 in. beam width and a 6-3/4 in. post width, making it suitable for projects using timber members of those dimensions.

What fasteners are required for installation, and are they included?

Installation requires 30 Strong-Drive SDS Heavy-Duty Connector screws sized 1/4 in. x 2-1/2 in. (Model: SDS25212). These screws are included with the column cap.

Why are SDS screws used instead of standard through bolts?

The Strong-Drive SDS screws provide a lower profile than standard through bolts for a cleaner installation, and they attach to a greater net section area of the column than a bolt attachment normally allows, improving the overall strength of the connection.

What material and finish is the CCQ77SDS2.5 made from?

The column cap is constructed from heavy-duty 3-gauge steel and features a Simpson Strong-Tie gray paint finish. It also includes certified welds for confidence in strength and loading performance.
