The Simpson CCQ68SDS2.5HDG is a 6 x 8 Column Cap with SDS Screws engineered to deliver strong, reliable column-to-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 load from the beam and provide critical support for the connection. Featuring Strong-Drive SDS Heavy-Duty Connector screws for fast installation, this column cap attaches to a greater net section area of the column than standard bolt attachment - all in a lower-profile, high-strength package. Finished in Hot Dip Galvanized coating for corrosion resistance, the CCQ68SDS2.5HDG is built for demanding structural applications where load performance and installation efficiency matter most.

Key Features

• Extended bearing seat - The seat of the column cap provides additional surface area of bearing that extends beyond each side of the column, helping distribute load from the beam and support the connection
• Strong-Drive SDS screws included - Uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation and attachment to a greater net section area of the column than a bolt attachment normally entails
• Lower profile fastening - The SDS screws provide a lower profile than standard through bolts
• Certified welds - Certified welds for confidence in strength and loading
• Enhanced uplift performance - Uplift loads have been increased for earthquake or wind loading
• Diamond holes - Diamond holes for temporary fastening during installation
• Hot Dip Galvanized finish - Provides corrosion protection suited for exposed or treated-lumber environments
• Made in the United States - Domestically manufactured for consistent quality

Specifications

• Model Number: CCQ68SDS2.5HDG
• Size: 6x Beam, 8x Post
• Thickness: 7 gauge
• Finish: Hot Dip Galvanized
• Country of Origin: United States

Approved Applications

• Wood column-to-beam connections in residential and commercial construction
• Structural connections requiring enhanced load distribution beyond the column face
• Applications subject to elevated uplift demands from earthquake or wind loading
• Projects where a lower-profile fastener solution is preferred over standard through bolts
• Installations requiring fast, screw-driven assembly with certified weld integrity

What's Included

• 1 x CCQ68SDS2.5HDG Column Cap (Hot Dip Galvanized)
• 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws (provided with the column cap)

Installation Notes

• Install with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap
• Important: Lag screws will not achieve the same load - use only the specified SDS screws
• For field-welding applications to pipe or other columns, the CCOQ and ECCOQ column cap only (no straps) versions may be ordered - dimensions are the same as the CCQ and ECCQ
• For rough-cut lumber sizes, contact us for assistance

Frequently Asked Questions

Can I use lag screws instead of the provided SDS screws?

No. 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.

Why does the column cap seat extend beyond the sides of the column?

The extended bearing surface helps distribute the load from the beam and provide support for the connection, resulting in a stronger, more stable column-beam joint.

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

Yes. Uplift loads have been increased for earthquake or wind loading, making the CCQ68SDS2.5HDG appropriate for applications where elevated uplift performance is required.
