Product Description
The Simpson Strong-Tie ECCQ7.1-8SDS2.5 End Column Cap is engineered to deliver strong, reliable column-beam connections in end-of-beam applications throughout wood construction. Designed to fit a 7-inch beam width and a nominal 8x post, this heavy-duty column cap eliminates the need for additional brackets or braces in most project configurations. The cap's seat provides an extended bearing surface area that reaches beyond the side of the column, helping to efficiently distribute load from the beam while reinforcing the overall connection integrity.
Built from 3-gauge steel with a Simpson Strong-Tie gray paint finish and featuring certified welds, the ECCQ7.1-8SDS2.5 is a trusted solution for demanding structural applications. It ships complete with 28 included Strong-Drive SDS Heavy-Duty Connector screws (1/4 in. x 2-1/2 in.), enabling faster installation with a lower profile than traditional through-bolt connections - all while engaging a greater net section area of the column for superior holding strength.
Key Features
- Lower-Profile Fastening: Strong-Drive SDS screws provide a lower profile than standard through bolts, keeping connections clean and tight.
- Certified Welds: Certified welds deliver confidence in strength and consistent load performance.
- Enhanced Uplift Resistance: Uplift loads have been increased to meet the demands of earthquake or wind loading conditions.
- Diamond Holes for Temporary Fastening: Diamond holes allow for easy temporary fastening during installation and alignment.
- Extended Bearing Surface: The seat of the column cap extends beyond the side of the column, distributing beam load more effectively.
- 3-Gauge Steel Construction: Heavy-duty 3-gauge steel delivers superior structural integrity and long-term durability.
- Gray Paint Finish: Simpson Strong-Tie gray paint finish provides a consistent, professional appearance.
- Made in the United States: Manufactured domestically for assured quality standards.

Frequently Asked Questions
- What beam and post sizes is the ECCQ7.1-8SDS2.5 compatible with?
- This end column cap is designed to fit a 7-inch beam width and a nominal 8x post size. It is intended for end-of-beam applications in wood construction.
- What fasteners are included, and do I need to purchase them separately?
- The ECCQ7.1-8SDS2.5 ships with 28 Strong-Drive SDS Heavy-Duty Connector screws (1/4 in. x 2-1/2 in., Model: SDS25212) included in the package, so no separate fastener purchase is necessary for installation.
- Why are SDS screws used instead of standard through bolts?
- Strong-Drive SDS 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, resulting in a cleaner connection with superior holding strength.
- What material and finish is this column cap made from?
- The ECCQ7.1-8SDS2.5 is made from 3-gauge steel with a Simpson Strong-Tie gray paint finish. It also features certified welds for confidence in strength and loading, and its uplift loads have been increased to meet the demands of earthquake or wind loading conditions.
