The Simpson ECCQ End Column Cap for 4x Beam, 4x Post with Strong-Drive SDS Screws by Simpson Strong-Tie is purpose-built to deliver strong, reliable column-to-beam connections in end-of-beam applications throughout wood construction. The cap's extended seat reaches beyond the side of the column to provide additional bearing surface area, helping distribute load from the beam and reinforce the overall connection. Included Strong-Drive SDS Heavy-Duty Connector screws make installation faster while engaging a greater net section area of the column than standard bolt attachments - resulting in a high-performance connection without the bulk of traditional hardware.

Key Features

• Strong-Drive SDS Heavy-Duty Connector screws included - everything needed to complete the connection ships in the box, eliminating a separate fastener purchase and speeding up installation on the job site.
• Lower-profile SDS screw attachment - screws sit closer to the surface than standard through bolts, reducing interference with adjacent framing members and giving the finished connection a cleaner appearance.
• Extended seat with additional bearing surface - the seat projects beyond the side of the column to spread the beam load over a wider area, improving load distribution and connection stability.
• Certified welds - factory-certified weld quality gives builders confidence in the cap's rated strength and load capacity from installation through the life of the structure.
• Increased uplift load ratings for seismic and wind events - uplift values have been engineered upward to meet the demands of earthquake and high-wind loading, making this cap well suited for challenging regional conditions.
• Diamond holes for temporary fastening - allow the cap to be quickly tacked in position during layout before final fastening, reducing the need for a second set of hands and keeping the work moving efficiently.
• 7-gauge steel construction - heavy-gauge steel provides the structural integrity and durability required for demanding post-and-beam applications.
• Simpson Strong-Tie gray paint finish - a tough painted coating helps protect the steel during handling and installation in typical covered or interior wood construction environments.

Why This Product

• Designed specifically for end-of-beam column connections - unlike general-purpose hardware, the ECCQ is engineered from the ground up for end-of-beam wood construction applications, so the geometry and load paths are optimized for exactly this use case.
• Fasteners included for a complete, ready-to-install solution - the 28 Strong-Drive SDS Heavy-Duty Connector screws that ship with the cap are the correct fastener for the connection, so there is no guesswork about compatibility and no additional trip to source hardware.
• Built to perform under seismic and wind loading - with uplift loads specifically increased for earthquake and wind events, this column cap is a dependable choice for projects in high-wind or seismic regions where standard connectors may fall short of code requirements.
• American-made Simpson Strong-Tie quality with certified welds - backed by Simpson Strong-Tie's engineering standards and certified weld processes, this cap delivers the verified strength and consistency that structural applications demand.

Frequently Asked Questions

What type of screws are included, and how many come with the ECCQ44SDS2.5?

The ECCQ44SDS2.5 includes 28 Strong-Drive SDS Heavy-Duty Connector screws measuring 1/4 in. x 2-1/2 in. (Model: SDS25212). These screws are used to fasten the cap to both the beam and the post.

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 allow attachment to a greater net section area of the column, resulting in a strong, efficient connection with faster installation.

Is the ECCQ44SDS2.5 suitable for use in high-wind or seismic zones?

Yes. Uplift loads for the ECCQ have been increased to accommodate earthquake or wind loading, making it well suited for applications in high-wind and seismic regions.

What is the gauge and finish of this column cap?

The ECCQ44SDS2.5 is manufactured from 7-gauge steel and features a Simpson Strong-Tie gray paint finish for durability and consistent appearance in wood construction applications.
