The Simpson CCQ46SDS2.5-R CCQ Column Cap for 4x Beam, 6x Post with Strong-Drive SDS Screws by Simpson Strong-Tie is engineered to deliver strong, reliable column-beam connections in wood construction. The extended bearing seat projects beyond each side of the column, distributing load from the beam across a greater surface area for enhanced support at the connection point. Rather than standard through bolts, this column cap relies on Strong-Drive SDS Heavy-Duty Connector screws for fast installation and attachment to a greater net section area of the column, generally eliminating the need for additional brackets or braces.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - 30 screws are included in the box, so you can begin installation immediately without sourcing additional fasteners separately.
• Lower-profile SDS screws instead of through bolts - reduces hardware bulk at the connection point for a cleaner appearance while maintaining a stronger attachment to the column's net section area.
• Extended bearing seat beyond each side of the column - spreads beam load across a greater surface area, reducing stress concentration and providing superior support at the post-to-beam junction.
• Certified welds - factory-verified weld quality gives builders confidence in the structural integrity and load capacity of every connection.
• Increased uplift load ratings for seismic and wind events - enhanced uplift capacity means this column cap is well-suited for structures in earthquake-prone or high-wind regions where code compliance is critical.
• Diamond holes for temporary fastening - allows the cap to be held in position during layout and alignment before final fastening, saving time and reducing the chance of installation errors.
• 7-gauge steel construction - heavy-gauge material provides the structural mass needed to handle demanding post-and-beam applications without flex or distortion under load.
• Simpson Strong-Tie gray paint finish - a durable factory-applied coating helps protect the steel during handling and installation.

Why This Product

• A complete connection solution in one package - the CCQ column cap arrives with all 30 required Strong-Drive SDS screws included, meaning no separate trip to source compatible fasteners before the job can start.
• Designed for demanding load conditions - certified welds and increased uplift load ratings make this cap a dependable choice for post-and-beam assemblies that must meet seismic or wind load requirements.
• Faster installation than traditional bolted hardware - SDS screw installation is quicker than drilling for and setting standard through bolts, and the lower-profile result keeps the connection area clean and unobstructed.
• Extended seat design reduces the need for supplemental hardware - the additional bearing surface built into the CCQ design generally eliminates the need for extra brackets or braces, simplifying the connection and keeping material costs down.

Frequently Asked Questions

What fasteners are used to install the CCQ46SDS2.5-R, and are they included?

This column cap installs with (30) 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212), which are included with the column cap. Lag screws will not achieve the same load.

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, offering both a cleaner appearance and stronger connection.

What is the purpose of the extended bearing seat on the CCQ column cap?

The seat of the column cap provides an additional surface area of bearing that extends beyond each side of the column. This extended bearing surface helps distribute the load from the beam and provides greater support for the connection.

Is this column cap suitable for use in high-wind or seismic regions?

Yes. Uplift loads have been increased for earthquake or wind loading, and the CCQ46SDS2.5-R features certified welds for confidence in strength and loading, making it appropriate for demanding structural applications.
