The Simpson ECCQ End Column Cap for 4x Beam, 6x Post with Strong-Drive SDS Screws by Simpson is engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications in wood construction. The seat of the column cap provides an additional bearing surface that extends beyond the side of the column, helping distribute the load from the beam and provide solid support for the connection. Strong-Drive SDS Heavy-Duty Connector screws are included for fast installation and allow attachment to a greater net section area of the column than standard bolt connections typically allow - making this connector a dependable choice for structural post and beam framing.

Key Features

• SDS screws provide a lower profile than standard through bolts - results in a cleaner, less obtrusive connection that maintains structural integrity without the bulk of traditional bolt hardware
• Certified welds - gives buyers confidence in the connector's strength and load performance on every installation
• Uplift loads increased for earthquake or wind loading - makes this column cap a suitable choice for structures in high-wind or seismic zones where enhanced resistance is critical
• Diamond holes for temporary fastening - allows the connector to be held in position during layout and alignment before final fastening, improving installation accuracy
• Made from 7-gauge steel - heavy-duty material thickness supports demanding structural load requirements in post and beam applications
• Simpson Strong-Tie gray paint finish - provides a consistent, finished appearance and a baseline level of protection for the steel connector

Why This Product

• Everything needed for installation is included - the connector ships with a full set of 28 Strong-Drive SDS Heavy-Duty Connector screws, eliminating the need to source fasteners separately and keeping your project on schedule
• Extended bearing seat for superior load distribution - the seat of the column cap reaches beyond the side of the column, spreading beam load over a greater surface area for a more stable and secure structural connection
• Designed for end-of-beam applications - the ECCQ geometry is purpose-built for end column cap use, generally eliminating the need for additional brackets or braces and simplifying the overall connection design
• Built for resilience in demanding conditions - with uplift loads increased for earthquake or wind loading and certified welds throughout, this connector is well-suited for structural applications where performance under lateral and uplift forces matters

Frequently Asked Questions

What type of fasteners are used with the ECCQ46SDS2.5, and are they included?

The ECCQ46SDS2.5 uses 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws. A full set of (28) screws (Model: SDS25212) is included with the connector, so no separate fastener purchase is necessary.

What is the advantage of SDS screws over standard through bolts for this application?

Strong-Drive SDS Heavy-Duty Connector screws provide a lower profile than standard through bolts and allow attachment to a greater net section area of the column, resulting in a stronger and cleaner connection while also speeding up installation.

Is the ECCQ46SDS2.5 suitable for use in areas subject to high wind or seismic activity?

Yes. The ECCQ46SDS2.5 features uplift loads that have been increased specifically for earthquake or wind loading conditions, making it well suited for use in regions where these forces are a design consideration.

What beam and post sizes is this column cap designed for?

The ECCQ46SDS2.5 is designed for a nominal 4x beam width and a nominal 6x post size, providing a properly fitted and structurally sound connection between those member sizes in end-of-beam applications.
