The Simpson Strong-Tie ECCQ86SDS2.5 is an end column cap engineered to deliver robust column-to-beam connections in wood construction applications where beams terminate at the column end. Designed for use with an 8x beam and 6x post, this heavy-duty connector features a seat that extends beyond the side of the column to provide an enlarged bearing surface area, helping to distribute loads more effectively from the beam down through the post. Constructed from 3-gauge steel and finished in Simpson Strong-Tie Gray paint, the ECCQ86SDS2.5 arrives ready for fast, reliable installation with all required Strong-Drive SDS Heavy-Duty Connector screws included.
Key Features
- Designed for end-of-beam column-to-beam connections in wood construction
- Extended seat bearing surface distributes beam load beyond the side of the column for added support
- Constructed from heavy-duty 3-gauge steel for maximum strength and durability
- Finished in Simpson Strong-Tie Gray paint for corrosion resistance
- SDS screws provide a lower profile than standard through bolts
- SDS screw attachment engages a greater net section area of the column compared to standard bolt attachment
- Certified welds for confidence in strength and loading
- Uplift loads have been increased for earthquake or wind loading
- Diamond holes for temporary fastening during installation
- All required 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws included - no separate hardware purchase needed
- Made in the United States

What's Included
- 1 x ECCQ86SDS2.5 End Column Cap
- 14 x 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws (Beam)
- 14 x 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws (Post)
Installation
Fasten with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. The diamond holes allow for temporary fastening during positioning before final installation. SDS screws attach to a greater net section area of the column than a bolt attachment normally entails, providing a stronger, lower-profile connection.

Frequently Asked Questions
- What beam and post sizes is the ECCQ86SDS2.5 designed to work with?
- The ECCQ86SDS2.5 is specifically engineered for use with an 8x beam and a 6x post, making it important to confirm your lumber dimensions match before installation.
- What type of fasteners are required, and are they included?
- This column cap uses 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws for attachment. All required screws are included with the connector, so no separate hardware purchase is needed.
- What is the advantage of using SDS screws over standard through bolts on this connector?
- SDS screw attachment provides two key advantages over standard through bolts: the screws deliver a lower profile installation, and they engage a greater net section area of the column compared to standard bolt attachment, helping to maintain the structural integrity of the post.
- What is this connector made from, and where is it manufactured?
- The ECCQ86SDS2.5 is constructed from heavy-duty 3-gauge steel and finished in Simpson Strong-Tie Gray paint for corrosion resistance. It is manufactured in the United States.
