The Simpson CCQ48-SDS2.5HDG is a 4x beam by 8x post column cap engineered to deliver strong, reliable column-to-beam connections in wood construction. Constructed from 7-gauge steel with a Hot Dip Galvanized finish for corrosion resistance, this column cap features an extended seat that provides additional bearing surface area beyond each side of the column - helping to distribute beam loads evenly and reinforce the overall connection. Designed for use with Strong-Drive SDS Heavy-Duty Connector screws (included), the CCQ48-SDS2.5HDG delivers fast, high-strength installation while engaging a greater net section area of the column than traditional bolt attachments. Made in the United States.

Key Features

• The extended bearing seat distributes the load from the beam and provides added support for the connection
• The SDS screws provide a lower profile than standard through bolts
• Certified welds for confidence in strength and loading
• Uplift loads have been increased for earthquake or wind loading
• Diamond holes for temporary fastening
• Uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation
• Attaches to a greater net section area of the column than a bolt attachment normally entails
• Designed for rough-cut lumber sizes

Frequently Asked Questions

What lumber sizes is the CCQ48-SDS2.5HDG designed to work with?

The CCQ48-SDS2.5HDG is designed for use with a 4x beam and an 8x post. It is specifically engineered for rough-cut lumber sizes, making it suitable for applications where rough-cut dimensional lumber is used rather than standard dressed lumber.

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

This column cap is designed for use with Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than a traditional bolt attachment.

What finish does the CCQ48-SDS2.5HDG have, and why does it matter?

The CCQ48-SDS2.5HDG features a Hot Dip Galvanized finish, which provides corrosion resistance. This makes it well suited for exterior or exposed applications where moisture and environmental conditions could otherwise compromise the integrity of the connection over time.

Is this column cap suitable for structures in high-wind or seismic zones?

Yes. The CCQ48-SDS2.5HDG features increased uplift load capacity specifically intended to address earthquake and wind loading requirements, making it appropriate for structures in regions where enhanced uplift resistance is needed.
