The Simpson CCOS4.62 Steel Column Cap is a heavy-duty connector built for high-capacity column-to-beam applications where a steel column is present. This cap-only design - without column straps - was created specifically for field welding to a steel column, allowing crews to work efficiently in structural steel environments. Attachment to the column cap plate is handled with the included self-tapping screws for a faster, more streamlined installation. Made from 7-gauge steel with a G90 zinc galvanized finish, this column cap is engineered to handle the demands of larger girder reactions in both solid sawn lumber and engineered wood product framing.

Key Features

• Adequate bearing length for larger girder reactions - supports heavy structural loads where undersized connectors would fall short, making it a reliable choice for demanding beam-to-column connections.
• Compatible with both solid sawn lumber and engineered wood products - gives builders and engineers flexibility to specify the beam material that best suits the project without needing a different connector.
• Self-tapping screws included - eliminates a separate fastener purchase and speeds up attachment to the column cap plate, keeping the job moving.
• 7-gauge steel construction - delivers the structural rigidity and load-transfer capacity expected in heavy-framing column cap applications.
• G90 zinc galvanized coating - provides a high level of corrosion resistance, keeping the connector protected in exposed or moisture-prone construction environments over the long term.
• Cap-only configuration designed for field welding - the absence of column straps makes this connector purpose-built for steel column integration, reducing unnecessary hardware and simplifying the connection detail.

Why This Product

• Purpose-built for steel column integration - unlike standard column caps, this strap-free design was engineered specifically for field welding to a steel column, making it the correct connector for steel-to-timber framing transitions rather than a workaround.
• Faster installation with included fasteners - the four included self-tapping screws and a straightforward screw-and-nail attachment method reduce setup time and eliminate guesswork about which fasteners to source separately.
• High-capacity performance for triple-beam framing - sized for triple 2x10 and triple 2x12 members, this column cap handles the larger girder reactions that come with heavy structural framing, where a lighter connector would not be appropriate.
• Long-term durability in demanding environments - the G90 galvanized finish on 7-gauge steel provides corrosion protection suited to the tough conditions common in structural construction, helping the connection maintain its integrity over time.
