The Simpson CCQ44-SDS2.5HDG CCQ HDG Column Cap for 4x Beam, 4x Post with Strong-Drive SDS Screws by Simpson Strong-Tie is engineered to deliver strong, reliable column-to-beam connections in wood construction. Sized for 4x beams and 4x posts, this column cap features an extended bearing seat that distributes load beyond each side of the column, generally eliminating the need for additional brackets or braces. Fabricated from 7-gauge steel with a hot-dip galvanized finish, the cap is built for exterior and treated-wood applications where corrosion resistance is essential. Thirty 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws are included, enabling fast installation while attaching to a greater net section area of the column than standard bolt attachments.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - provides faster installation and attaches to a greater net section area of the column than a bolt attachment normally entails, resulting in a stronger, more efficient connection.
• Low-profile SDS screw fastening - screws sit lower than standard through bolts, keeping the connection clean and reducing interference with surrounding structure.
• Extended bearing seat design - distributes load from the beam beyond each side of the column, improving support and generally reducing the need for supplemental brackets or braces.
• Certified welds - provides confidence in strength and loading performance, giving builders assurance in demanding structural applications.
• Increased uplift load capacity - uplift loads have been increased for earthquake or wind loading, making this cap appropriate for high-wind and seismic zones.
• Diamond holes for temporary fastening - allows the cap to be held securely in position during layout and alignment before final installation.
• 7-gauge steel construction - heavy-gauge material contributes to the structural integrity and load capacity of the connection.
• Hot-dip galvanized finish - offers extra corrosion resistance for exterior and treated-wood applications, extending the service life of the connection in harsh or exposed environments.

Why This Product

• All-in-one column-to-beam solution - the extended bearing seat and included SDS screws combine to create a complete, high-capacity connection without requiring additional hardware, saving time and simplifying the build process.
• Built for demanding outdoor and treated-wood projects - hot-dip galvanization provides a higher level of corrosion resistance than standard coatings, making this cap a dependable choice for decks, pergolas, and other exterior structures where treated lumber is used.
• Engineered for code-sensitive applications - certified welds and increased uplift load ratings address earthquake and wind loading requirements, giving contractors and inspectors confidence in the connection's structural performance.
• Faster installation without sacrificing strength - the Strong-Drive SDS screws eliminate the need for drilling through-bolt holes, cutting labor time while achieving attachment to a greater net section area of the post than conventional bolt connections.

Frequently Asked Questions

Why are SDS screws used instead of standard through bolts?

The Strong-Drive SDS Heavy-Duty Connector screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than a bolt attachment normally entails, resulting in faster installation and strong, reliable connections.

Is this column cap suitable for exterior or treated-wood applications?

Yes. The hot-dip galvanization (HDG) finish offers extra corrosion resistance specifically for exterior and treated-wood applications, making the CCQ44-SDS2.5HDG appropriate for outdoor structures and environments where treated lumber is used.

Does this column cap help in high-wind or seismic zones?

Yes. Uplift loads have been increased for earthquake or wind loading, and certified welds provide confidence in strength and loading performance under demanding conditions.

Do the SDS screws come included with this column cap?

Yes. The CCQ44-SDS2.5HDG includes (30) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212). Note that lag screws will not achieve the same load.
