The Simpson ECCQ3-6SDS2.5HDG End Column Cap w/SDS Screws - Hot Dip Galvanized enhances the strength and stability of your construction projects. Crafted from durable heavy-gauge steel, this column cap is designed to provide column-to-beam connections in end-of-beam applications for wood construction.

The seat of the column cap features additional surface area beyond the side of the column to allow added area of bearing to distribute the load from the beam and provide enhanced support for the connection.

This product is intended for use with 6x posts or columns but is also available in a wide range of other sizes and both nominal and rough-cut lumber. Included with this column cap are the necessary Simpson Strong-Drive SDS connector screws to provide fast installation and lower profile than standard bolts.


  • Connection Type: Provides strong end-of-beam connection for column-to-beams and the extended area of the column seat offers additional surface area of bearing to distribute the load.
  • Lumber Size: Intended for use with 3-1/8x beams and 6x posts/columns.
  • Material and Finish: Made from Steel for durability and finished with Hot Dip Galvanized coating.
  • Performance: Certified welds for strength and loading with increased uplift loads for earthquake or wind loading.
  • Installation Design:Features diamond holes to provide temporary fastening during installation, bolt spacing to meet NDS code requirements.
