Simpson Strong-Tie CCO4/6HDG Column Cap is a hot-dip galvanized, heavy-duty column cap engineered by Simpson Strong-Tie to deliver strong, reliable column-to-beam connections on top of steel columns. Designed for a 4x beam with a 6.5-inch column height, this connector features a legless design that allows for field-welded attachment to steel columns and posts, making it an ideal solution for structural connections requiring superior load transfer and corrosion resistance.

Key Features

• Legless design enables field-welded attachment directly to steel columns and posts
• Extended seat provides additional bearing surface area beyond each side of the column to distribute beam loads effectively
• Uplift loads increased for earthquake or wind loading
• Bolt spacing meets NDS code requirements to ensure optimal performance
• Diamond holes allow for temporary fastening during installation
• Hot-dip galvanized finish provides enhanced corrosion resistance for demanding environments
• Constructed from 7-gauge steel for exceptional strength and durability

Installation

• Use all specified fasteners; see General Notes
• Weld by designer
• Bolt holes shall be a minimum of 1/32" to a maximum of 1/16" 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 that are not through the wide face

Frequently Asked Questions

What type of columns is the CCO4/6HDG designed to attach to?

The CCO4/6HDG features a legless design specifically intended for field-welded attachment to steel columns and posts. It can also be ordered for field welding to pipe or other column profiles, with welding performed by the designer.

Why does the seat of the CCO column cap extend beyond the column sides?

The extended seat of the column cap provides additional surface area for bearing that reaches beyond each side of the column. This design helps distribute the load from the beam more evenly and provides enhanced support at the connection point.

Is the CCO4/6HDG suitable for use in high-wind or seismic regions?

Yes. The CCO4/6HDG is engineered with increased uplift load capacity specifically to address the demands of earthquake and wind loading conditions, making it well-suited for use in seismic and high-wind design applications.

What are the bolt hole requirements for installing the CCO4/6HDG?

Per 2018 NDS, section 12.1.3.2, bolt holes must be a minimum of 1/32" to a maximum of 1/16" larger than the bolt diameter. Holes should be drilled from one side all the way through the beam to maintain proper hole tolerances and ensure a code-compliant connection.
