The Simpson Strong-Tie ECCO6HDG is an end column cap engineered to deliver robust column-to-beam connections in end-of-beam applications atop steel members. Constructed from 7-gauge steel with a Hot Dip Galvanized (HDG) finish, this connector features a legless design that enables field-welded attachment directly to steel columns and beams. The extended seat provides additional bearing surface area beyond one side of the column, effectively distributing load from the beam and reinforcing the integrity of the connection. Sized for beams measuring 5-1/4 in. to 5-1/2 in. wide, the ECCO6HDG delivers the performance and corrosion resistance demanded by demanding structural applications.

Approved Applications
- End-of-beam column-to-beam connections atop steel members
- Structural connections requiring field-welded attachment to steel columns and beams
- Applications demanding increased uplift resistance for seismic (earthquake) or high-wind loading conditions
- Connections to pipe columns or other non-standard column profiles via field welding
- Projects requiring NDS code-compliant bolt spacing for engineered wood connections
Installation
- Use all specified fasteners as directed in manufacturer documentation.
- Bolt holes shall be a minimum of 1/32 in. to a maximum of 1/16 in. larger than the bolt diameter (per 2018 NDS, section 12.1.3.2); bolt holes should be drilled from one side all the way through the beam to maintain hole tolerances.
- Contact engineered wood manufacturers for connections involving engineered wood products.
- Weld attachment to steel columns or beams to be performed by designer.

Frequently Asked Questions
- What beam widths is the ECCO6HDG designed to accommodate?
- The ECCO6HDG is sized for beams measuring 5-1/4 in. to 5-1/2 in. wide, making it suitable for standard 6x lumber and similar engineered wood members within that width range.
- How is the ECCO6HDG attached to the column and beam?
- The ECCO6HDG features a legless design that is intended for field-welded attachment directly to steel columns and beams. Diamond holes are also provided for convenient temporary fastening during installation prior to final welding.
- What finish does the ECCO6HDG have, and why does it matter?
- The ECCO6HDG is finished with a Hot Dip Galvanized (HDG) coating, which provides exceptional corrosion resistance. This makes it well suited for exposed or demanding environments where standard finishes may not offer adequate protection.
- What is the purpose of the extended seat on the ECCO6HDG?
- The extended seat provides additional bearing surface area beyond one side of the column, which helps distribute load from the beam more effectively and reinforces the integrity of the connection in end-of-beam applications atop steel members.
