The Simpson CCQ46SDS2.5 CCQ Column Cap by Simpson Strong-Tie is engineered to deliver high-capacity column-to-beam connections in wood construction, fitting a nominal 4x beam and 6x post. The extended bearing seat reaches beyond each side of the column, distributing load from the beam and providing additional support at the connection point. In place of traditional through bolts, the cap uses Strong-Drive SDS Heavy-Duty Connector screws, which attach to a greater net section area of the column and speed up installation without sacrificing structural integrity. The result is a strong, low-profile connection well suited to demanding structural applications, including post-and-beam framing in earthquake or high-wind environments.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - fasten to a greater net section area of the column than a bolt attachment normally allows, producing a stronger, more reliable connection
• Lower profile than standard through bolts - SDS screws sit flush and streamlined, keeping the finished assembly clean and reducing interference with adjacent framing members
• Certified welds - provide verified confidence in the cap's strength and load-carrying capacity so builders can rely on published load values
• Increased uplift load ratings for earthquake and wind loading - the cap is designed to handle the heightened lateral and uplift forces common in seismic and high-wind zones, broadening its range of approved applications
• Extended bearing seat - the seat surface area reaches beyond each side of the column, distributing beam load more evenly and adding support at the critical connection point
• Diamond holes for temporary fastening - allow the cap to be tacked in position during layout before final fastening, reducing the risk of misalignment during assembly
• 7-gauge steel construction - heavy-gauge material provides the structural rigidity required for demanding column-beam connections in wood framing
• Simpson Strong-Tie gray paint finish - factory-applied coating helps protect the steel during construction and provides a consistent, professional appearance

Why This Product

• Engineered for seismic and high-wind performance - uplift loads have been increased specifically for earthquake and wind loading, making this column cap a dependable choice for structural connections in demanding code environments
• Faster installation without sacrificing strength - Strong-Drive SDS screws replace traditional through bolts, cutting installation time while achieving attachment to a greater net section area of the column for a superior structural connection
• Built-in load distribution - the extended bearing seat spreads the load from the beam across a larger surface area beyond the column edges, reducing stress concentrations at the connection and supporting long-term structural performance
• Confidence through certified quality - certified welds and heavy 7-gauge steel construction back every cap with verifiable strength and loading assurance, giving contractors and inspectors a reliable foundation for structural approval

Frequently Asked Questions

What lumber dimensions does this column cap fit?

The CCQ46SDS2.5 is designed for a nominal 4x beam width and a nominal 6x post size, making it suitable for those specific column-beam combinations in wood construction.

Why are SDS screws used instead of standard through bolts?

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, resulting in faster installation and a strong, streamlined connection.

Is this column cap rated for use in high-wind or seismic zones?

Yes. Uplift loads have been increased for earthquake or wind loading, and the CCQ features certified welds for added confidence in strength and loading under these demanding conditions.

Can the CCQ46SDS2.5 be used with field-welding to pipe or other non-wood columns?

The CCQ column cap with legs is designed for wood construction. For field-welding to pipe or other columns, the CCOQ or ECCOQ (column cap only, no straps) versions may be ordered separately, as those share the same dimensions as the CCQ and ECCQ.
