The Simpson Strong-Tie ECCQ106SDS2.5 is a heavy-duty end column cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam wood construction applications. Fabricated from 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this column cap features an extended seat bearing surface that projects beyond the side of the column, helping to distribute beam loads more effectively across the connection point. Included 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws simplify installation while engaging a greater net section area of the column compared to standard through-bolt attachments - making the ECCQ106SDS2.5 a performance-forward choice for demanding structural connections.
Key Features
- Extended seat bearing surface distributes beam load beyond the side of the column for improved support
- SDS screws provide a lower profile than standard through bolts
- Certified welds for confidence in strength and load capacity
- Uplift loads have been increased to meet earthquake and wind loading demands
- Diamond holes allow for temporary fastening during installation
- Strong-Drive SDS screws attach to a greater net section area of the column than bolt attachment typically allows
- Made in the United States

Approved Applications
- End-of-beam column-to-beam connections in wood construction
- Structural applications requiring increased uplift resistance for earthquake or wind loading
- Post-and-beam framing where extended bearing surface support is required
- Applications where a low-profile fastener connection is preferred over through-bolt solutions
- 10x beam and 6x post connections requiring a certified, engineered column cap
What's Included
-
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 extended seat of the column cap should be positioned to bear on the top of the column, with the cap aligned to support the end of the beam. Diamond holes are available for temporary fastening prior to final installation.

Frequently Asked Questions
- What beam and post sizes is the ECCQ106SDS2.5 designed to fit?
- The ECCQ106SDS2.5 is engineered for use with a 10x beam and a 6x post. The beam width accommodated is 9-1/4 in., with a W1 dimension of 9-1/2 in. and a W2 dimension of 5-1/2 in., an L dimension of 8-1/2 in., and an H dimension of 7 in.
- What fasteners are included, and why are they preferred over standard through bolts?
- The ECCQ106SDS2.5 includes 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector screws. These screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than bolt attachment typically allows, resulting in a stronger and less obtrusive connection.
- What material and finish is used on this column cap?
- The ECCQ106SDS2.5 is fabricated from 3-gauge steel and features a Simpson Strong-Tie Gray paint finish, providing a durable heavy-duty construction suitable for demanding structural applications.
- Is this column cap suitable for use in high-wind or seismic areas?
- Yes. The ECCQ106SDS2.5 features certified welds and uplift loads that have been increased specifically to meet earthquake and wind loading demands, making it appropriate for use in applications where enhanced lateral and uplift resistance is required.
