The Simpson Strong-Tie ECCQ3-6SDS2.5 is an ECCQ End Column Cap engineered to deliver strong, reliable column-beam connections in end-of-beam applications in wood construction. Designed for a 3-1/8 in. beam width and a nominal 6x post, this heavy-duty column cap features an extended seat that provides additional bearing surface area beyond the side of the column - helping to distribute load from the beam and provide enhanced support at the connection point. Built from 7-gauge steel with a Simpson Strong-Tie gray paint finish and manufactured in the United States, the ECCQ3-6SDS2.5 comes complete with 28 included Strong-Drive SDS Heavy-Duty Connector screws for fast, efficient installation. Simpson Strong-Tie column caps come in a variety of sizes to accommodate any project, generally eliminating the need for additional brackets or braces.

Key Features

• Lower Profile Fastening: Strong-Drive SDS screws provide a lower profile than standard through bolts, resulting in a cleaner, more compact installation.
• Certified Welds: Certified welds deliver confidence in strength and loading performance throughout the life of the connection.
• Increased Uplift Loads: Uplift loads have been increased to address earthquake or wind loading requirements in demanding structural applications.
• Extended Bearing Seat: The seat of the column cap extends beyond the side of the column to distribute load from the beam and support the connection more effectively.
• Diamond Holes for Temporary Fastening: Diamond holes allow for convenient temporary fastening during positioning and installation.
• Greater Net Section Area: SDS screws attach to a greater net section area of the column than bolt attachment normally entails, improving overall connection performance.
• 7-Gauge Steel Construction: Fabricated from heavy 7-gauge steel for robust structural performance.
• Simpson Strong-Tie Gray Paint Finish: Finished with Simpson Strong-Tie gray paint for corrosion resistance and consistent appearance.
• Made in the United States: Manufactured domestically to Simpson Strong-Tie's high quality standards.
