The Simpson Strong-Tie ECCQ98SDS2.5 is an 8x Post End Column Cap engineered to deliver strong, reliable column-to-beam connections in end-of-beam applications for wood construction. Fabricated from heavy-duty 3-gauge steel with a durable Simpson Strong-Tie Gray paint finish, this column cap features an extended seat that provides additional bearing surface area beyond the side of the column - helping to distribute loads from the beam more effectively and reinforcing the overall structural connection. Pre-packaged with 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws, the ECCQ98SDS2.5 is ready for fast, high-performance installation right out of the box, with no additional hardware required.
Key Features
-
Extended Bearing Seat: The seat of the column cap extends beyond the side of the column, providing additional surface area to help distribute beam loads and support the connection.
-
Strong-Drive SDS Screw Installation: Uses 1/4" x 2-1/2" Strong-Drive SDS Heavy-Duty Connector Screws for fast installation, attaching to a greater net section area of the column than standard bolt attachment.
-
Lower Profile Hardware: SDS screws provide a lower profile than standard through-bolts, resulting in a cleaner, less obtrusive installation.
-
Certified Welds: Welds are certified to provide confidence in strength and structural loading performance.
-
Increased Uplift Loads: Uplift load values have been increased to accommodate earthquake and wind loading demands.
-
Diamond Holes: Diamond-shaped holes are included for convenient temporary fastening during installation.
-
Made in the United States: Manufactured domestically for consistent quality assurance.
-
Screws Included: All required SDS screws are provided with the column cap - no separate hardware purchase necessary.
