The Simpson Strong-Tie 6X Beam Column Cap Hot-Dip Galvanized is a heavy-duty structural connector engineered to deliver strong, reliable column-to-beam connections on top of steel columns and posts. Its legless design accommodates field-welded attachment, making it well suited for structural assemblies where uplift demands from seismic or high-wind loading conditions require a code-conforming, load-distributing solution.

Key Features

• Legless design for field-welded attachment - connects directly to steel columns and posts without requiring pre-attached legs, giving installers flexibility to weld on-site to suit project conditions
• Extended seat that provides additional bearing surface area beyond each side of the column - distributes beam loads more effectively across the connection, reducing stress concentration and supporting structural integrity
• Uplift load values increased to meet earthquake and wind loading demands - provides added confidence in high-stress environments where seismic or high-wind forces place elevated demands on structural connections
• Bolt spacing meets NDS code requirements - helps ensure the assembly conforms to applicable structural codes without requiring additional field modifications or engineering workarounds
• 7 gauge steel construction with a hot-dip galvanized finish - delivers corrosion resistance suited to exposed or demanding environments, extending the service life of the connection

Why This Product

• Purpose-built for steel column connections - the legless configuration is specifically designed for field welding to steel columns and posts, including pipe columns, making this cap a practical fit for a wide range of structural steel applications
• Engineered for elevated uplift conditions - with load values designed to address earthquake and high-wind demands, this connector supports structural assemblies in regions or applications where standard hardware may fall short
• Domestically produced by a trusted structural hardware brand - Simpson Strong-Tie manufactures this connector in the United States, reflecting the quality standards and engineering expertise the brand is recognized for
• Code-conforming bolt spacing built in - NDS-compliant bolt hole placement is integrated into the connector's design, helping structural professionals maintain code conformance without additional layout work in the field

Frequently Asked Questions

What type of columns is the CCO6HDG designed to attach to?

The CCO6HDG features a legless design that enables field-welded attachment directly to steel columns and posts. It may also be ordered for field welding to pipe or other column types, with welding performed by the designer.

What beam widths are compatible with the CCO6HDG?

The CCO6HDG is compatible with beam widths of 5-1/4 inches and 5-1/2 inches, accommodating standard dimensional lumber in that range.

How does the CCO6HDG seat design help with load distribution?

The seat of the CCO6HDG extends beyond each side of the column, providing additional bearing surface area. This extended bearing helps distribute the load transferred from the beam and strengthens the overall connection.

Is the CCO6HDG suitable for high-wind or seismic applications?

Yes. The CCO6HDG features increased uplift load values specifically designed to accommodate the elevated demands of earthquake and wind loading conditions, making it appropriate for use in seismic and high-wind environments.
