The Simpson End Column Cap for Triple 2x Beam and 6x Post with Strong-Drive SDS Screws is a heavy-duty structural connector engineered to deliver strong, reliable column-to-beam connections in end-of-beam wood construction applications. The seat of this column cap extends beyond the side of the column, providing additional bearing surface area that helps distribute load from the beam and support the connection where it matters most. Rather than relying on standard through-bolt attachment, this connector uses Strong-Drive SDS Heavy-Duty Connector screws that fasten into a greater net section area of the column, combining fast installation with a lower-profile connection. Simpson column caps come in a variety of sizes to accommodate any project, generally eliminating the need for additional brackets or braces.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - 28 screws are included in the package, allowing the installer to get to work immediately without sourcing separate fasteners
• SDS screws provide a lower profile than standard through bolts - reduces hardware bulk at the connection point for cleaner, tighter post-and-beam assemblies
• Extended bearing seat beyond the column face - distributes beam load across a greater surface area, improving load transfer and structural support at end-of-beam conditions
• SDS screws attach to a greater net section area of the column - achieves a stronger grip on the column compared to conventional bolt attachment methods
• Certified welds - provides confidence in strength and loading, giving builders and inspectors a verifiable quality standard
• Uplift loads increased for earthquake or wind loading - makes this connector suitable for projects in high-wind or seismic zones where enhanced uplift resistance is required
• Diamond holes for temporary fastening - allows the cap to be held in position during layout and adjustment before final fastener installation, saving time on the job
• Made from 7-gauge steel with Simpson gray paint finish - delivers heavy-duty structural integrity with a corrosion-resistant painted coating suited for protected wood construction environments

Why This Product

• End-of-beam engineered specifically for triple 2x beam and 6x post configurations - the ECCQ is purpose-built for this member combination, so builders get a precise, load-rated fit without adapting a generic connector or adding supplemental bracing
• Faster installation without sacrificing connection strength - Strong-Drive SDS Heavy-Duty Connector screws drive quickly and engage more of the column's net section area than a bolt typically reaches, meaning less installation time and a more effective structural connection in one step
• Built-in uplift performance for demanding environments - with uplift loads increased for earthquake or wind loading and certified welds throughout, this connector is a strong choice for structural framing in regions where code requirements address lateral and uplift forces
• Eliminates the need for additional brackets or braces - Simpson column caps are sized to handle the full connection on their own, keeping the post-and-beam junction cleaner and reducing material and labor costs on the job site

Frequently Asked Questions

What beam and post sizes is the ECCQ4.62-5.50SDS designed to fit?

This end column cap is designed for a triple 2x nominal beam width and a 6x nominal post size, making it suited for heavy-duty wood construction connections at end-of-beam applications.

What fasteners are included, and why are SDS screws used instead of through bolts?

The connector includes 28 Strong-Drive SDS Heavy-Duty Connector screws (1/4 in. x 2-1/2 in., Model: SDS25212). SDS screws are used because they provide a lower profile than standard through bolts and attach to a greater net section area of the column than a typical bolt attachment, resulting in a stronger, cleaner connection.

What material and finish is this column cap made from?

The ECCQ4.62-5.50SDS is made from 7-gauge steel and finished in Simpson Strong-Tie gray paint for durability. It also features certified welds for confidence in strength and loading.

Is this connector suitable for use in high-wind or seismic conditions?

Yes. The ECCQ4.62-5.50SDS has uplift loads that have been increased to accommodate earthquake or wind loading, making it appropriate for use in areas subject to those conditions. The extended bearing seat also helps distribute load from the beam for additional support beyond the side of the column.
