The Simpson Strong-Tie CCQ46SS-SDS2.5 is a high-capacity 4x6 column cap engineered for demanding column-beam combinations. Constructed from stainless steel, this connector delivers maximum corrosion resistance in harsh exterior environments, making it an ideal solution for exposed or coastal applications. Unlike traditional bolted connections, this column cap is designed around Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws, which ship included with the hardware - enabling faster installation while preserving greater net section area of the column. The result is a stronger, lower-profile connection that meets the rigorous demands of modern structural applications.

Key Features

• Lower Profile Installation: SDS screws provide a lower profile than standard through bolts, reducing interference with surrounding materials.
• Faster Installation: Strong-Drive SDS Heavy-Duty Connector screws allow for quicker assembly compared to traditional bolt-and-nut methods.
• Greater Net Section Area: The screw-based design preserves more of the column's cross-sectional area compared to through-bolt connections.
• Certified Welds: Certified welds provide confidence in strength and structural loading performance.
• Enhanced Uplift Loads: Uplift load values have been increased to meet requirements for earthquake or wind loading conditions.
• Diamond Holes: Diamond-shaped holes allow for temporary fastening during the installation process.
• Stainless Steel Construction: Offers maximum corrosion resistance in harsh exterior conditions.

What's Included

• 1 x Simpson Strong-Tie CCQ46SS-SDS2.5 Stainless Steel Column Cap
• 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws (included 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 values and should not be substituted.
• CCOQ and ECCOQ column cap only (no straps) may be ordered for field-welding to pipe or other columns. Dimensions are the same as CCQ and ECCQ.

Frequently Asked Questions

What size column and beam is this cap designed for?

The CCQ46SS-SDS2.5 is specifically engineered for 4x6 column-beam combinations, making it suitable for demanding structural connections where that lumber dimension is required.

Do the SDS screws come included with this column cap?

Yes, Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws ship included with the hardware, so no separate fastener purchase is necessary for installation.

Why is a screw-based design preferable to traditional through-bolt connections?

The SDS screw-based design offers several advantages over traditional bolted connections: it provides a lower profile that reduces interference with surrounding materials, allows for faster assembly, and preserves greater net section area of the column by avoiding the material removal required for through-bolt holes.

Is this column cap suitable for coastal or exterior environments?

Yes, the CCQ46SS-SDS2.5 is constructed from stainless steel, which delivers maximum corrosion resistance. This makes it an ideal choice for exposed or coastal applications where harsh environmental conditions would compromise standard steel connectors.
