The Simpson CCQ66SDS2.5-R CCQ Column Cap is engineered to deliver strong, reliable column-beam connections in wood construction. Designed for a 6x beam and 6x post, this column cap features an extended seat that provides additional bearing surface area beyond each side of the column - helping to distribute load from the beam and reinforce the connection. Rather than standard through bolts, this model uses Strong-Drive SDS Heavy-Duty Connector screws for faster installation and attachment to a greater net section area of the column. Certified welds and 7-gauge steel construction give this cap the structural integrity demanded by both everyday builds and high-load applications involving seismic or wind forces. Strong-Drive SDS screws are included.

Key Features

• Lower Profile Fastening: SDS screws provide a lower profile than standard through bolts, resulting in a cleaner, less obtrusive connection.
• Certified Welds: Welds are certified for confidence in strength and load performance.
• Enhanced Uplift Resistance: Uplift loads have been increased to address earthquake or wind loading requirements.
• Diamond Holes: Diamond holes allow for temporary fastening during installation.
• Extended Bearing Seat: The seat extends beyond each side of the column to help distribute beam loads and support the connection.
• Heavy-Gauge Steel: Constructed from 7-gauge steel for exceptional strength and durability.
• Durable Finish: Simpson Strong-Tie gray paint finish for corrosion resistance and a professional appearance.
• Made in the USA: Manufactured in the United States.

What's Included

This column cap includes (30) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212). Note: Lag screws will not achieve the same load values - use only the provided SDS screws for rated performance.

Frequently Asked Questions

What size beam and post is the CCQ66SDS2.5-R designed for?

This column cap is designed for a nominal 6x beam and a nominal 6x post, making it suitable for heavy timber framing applications that require a strong column-beam connection.

What fasteners are required, and are they included?

This column cap installs with 30 Strong-Drive SDS Heavy-Duty Connector screws measuring 1/4 in. x 2-1/2 in. (Model: SDS25212). These screws are included with the cap, so no separate fastener purchase is necessary.

Why use SDS screws instead of standard through bolts?

The Strong-Drive SDS screws provide a lower profile than standard through bolts, resulting in a cleaner connection. They also attach to a greater net section area of the column than a bolt attachment normally allows, which contributes to stronger overall performance.

Is this column cap suitable for use in high-wind or seismic conditions?

Yes. The CCQ66SDS2.5-R features increased uplift load capacity specifically to address earthquake and wind loading requirements. Combined with certified welds and 7-gauge steel construction, it is well suited for applications where seismic or high-wind forces are a concern.
