The Simpson 8X Beam Column Cap CCO8 from Simpson is a heavy-duty connector engineered for column-to-beam connections on top of steel columns and posts. Its legless profile is purpose-built for field-welded attachment, making it a practical choice for structural applications where a traditional leg-based cap is not suitable. The extended bearing seat reaches beyond each side of the column to distribute beam loads across a wider surface area, supporting demanding structural requirements including seismic and high-wind loading conditions.

Key Features

• Legless design for field-welded attachment - allows direct welding to steel pipe columns or other column types without relying on legs, giving structural designers greater flexibility in steel column applications
• Extended bearing seat that projects beyond each side of the column - distributes beam loads over a larger area, improving connection performance and reducing stress concentrations at the support point
• Increased uplift load capacity for seismic and high-wind conditions - provides enhanced resistance where earthquake or wind loading demands exceed standard connection requirements, adding reliability in high-risk environments
• Bolt spacing that meets NDS code requirements - ensures compliance with engineered standards for wood-to-metal connections, simplifying plan review and inspection for builders and engineers
• Diamond holes for temporary fastening during installation - help secure the cap in position before final fasteners are driven, reducing the chance of misalignment and streamlining the installation process
• 3 gauge steel construction with no coating - delivers substantial material thickness suited to structural-grade loading, while the uncoated finish accommodates field welding without interference from surface treatments

Why This Product

• Engineered specifically for steel column tops - the legless, field-weld configuration addresses a common gap in column cap options, making the CCO8 a direct fit for steel pipe column and custom column applications where leg-based connectors simply will not work
• Built to perform under extreme loading - with uplift loads rated for earthquake and wind loading conditions, this cap is suited to projects in seismic zones or high-wind regions where connection integrity is a critical design concern
• Code-aligned fastener geometry - NDS-compliant bolt spacing removes guesswork for engineers and contractors, supporting smoother permitting and inspection on projects governed by current building codes
• American-made quality from Simpson - produced domestically by a brand with a long-standing reputation in structural connectors, the CCO8 carries the design consistency and material standards that engineers and builders rely on for load-rated structural connections

Frequently Asked Questions

What makes the CCO8 different from column caps that have legs?

The CCO8 features a legless design, which allows it to be field-welded directly to steel columns and posts rather than relying on leg-based mechanical fastening. This makes it well-suited for steel column applications where a welded connection is preferred or required by the designer.

How does the CCO8 seat help with load distribution?

The seat of the CCO8 extends beyond each side of the column, providing additional bearing surface area. This extended seat helps distribute the load transferred from the beam more evenly, supporting a stronger and more stable connection overall.

Is the CCO8 suitable for use in seismic or high-wind regions?

Yes. The CCO8 is designed with increased uplift load capacity to address the demands of earthquake and wind loading conditions, making it appropriate for use in regions with elevated seismic or wind design requirements.

What are the bolt hole requirements for installing the CCO8?

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. Bolt spacing is designed to meet NDS code requirements for optimal performance.
