Product Description
Simpson ECCQ3-6SS-SDS2.5 - ECCQ Stainless-Steel End Column Cap for 3-1/8 in. Beam & 6x Post with Strong-Drive SDS Screws
The Simpson Strong-Tie ECCQ3-6SS-SDS2.5 is a heavy-duty stainless-steel end column cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications in wood construction. Designed for a 3-1/8 in. beam width and a nominal 6x post, the ECCQ features an extended seat that provides additional bearing surface area beyond the side of the column - helping to distribute loads from the beam and reinforce the connection where it matters most. Fabricated from 7-gauge stainless steel, this connector offers high and severe corrosion resistance, making it ideal for demanding outdoor and coastal environments. Simpson Strong-Tie column caps come in a variety of sizes to accommodate a wide range of projects, generally eliminating the need for additional brackets or braces.
The ECCQ uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation and to attach to a greater net section area of the column than a standard bolt attachment normally entails, while maintaining a lower profile than traditional through bolts. Certified welds provide confidence in strength and load performance, and uplift loads have been increased to address earthquake and wind loading requirements.
Key Features
- Extended Bearing Seat: The column cap seat provides additional bearing surface area extending beyond the side of the column to help distribute beam loads and support the connection.
- Low-Profile Fastening: Strong-Drive SDS screws provide a lower profile than standard through bolts while attaching to a greater net section area of the column.
- Certified Welds: All welds are certified for confidence in strength and load performance.
- Enhanced Uplift Resistance: Uplift loads have been increased to meet earthquake and wind loading demands.
- Diamond Holes: Integrated diamond holes allow for temporary fastening during installation.
- High/Severe Corrosion Resistance: Made from stainless steel for use in high and severe corrosion environments.
- 7-Gauge Steel Construction: Heavy-duty 7-gauge stainless steel for superior strength and durability.
- Eliminates Extra Hardware: Designed to accommodate end-of-beam connections generally without the need for additional brackets or braces.

Frequently Asked Questions
- What beam and post sizes is this column cap designed for?
- The ECCQ3-6SS-SDS2.5 is specifically designed for a 3-1/8 in. beam width and a nominal 6x post. It is intended for end-of-beam applications in wood construction.
- What fasteners are required for installation, and are they included?
- Installation requires 28 stainless-steel 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws (Model: SDS25212SS). These screws are included with the connector. Note that stainless-steel fasteners are required when installing stainless-steel connectors.
- Why choose stainless steel over a standard steel version of this connector?
- The stainless-steel construction of the ECCQ3-6SS-SDS2.5 provides high and severe corrosion resistance, making it well suited for demanding outdoor and coastal environments where standard steel connectors may be prone to corrosion over time.
- What advantages do the SDS screws offer compared to 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, allowing for fast installation without sacrificing connection strength.
