The Simpson 3-1/4 in Beam Column Cap with SDS Screws Quick-Install is a heavy-duty connector engineered for column-to-beam connections on top of steel columns and posts. Its legless design allows for field-welded attachment directly to the column, providing a clean, low-profile fit where standard through-bolt hardware would be too bulky or intrusive. The extended seat delivers additional bearing surface beyond each side of the column, spreading beam loads across the connection for dependable structural performance in demanding framing assemblies.

Key Features

• Legless design for field-welded attachment - mounts flush to the top of steel columns and posts without added bulk, making it well-suited for low-profile structural connections where clearance is limited.
• Extended seat beyond each side of the column - distributes beam loads more broadly across the connection, improving load transfer and reducing point stress in the assembly.
• Includes Strong-Drive SDS Heavy-Duty Connector screws - these fasteners engage a greater net section area of the column than standard bolt attachments, speeding up installation while maintaining a strong, secure connection.
• 7-gauge steel construction - provides the material strength and rigidity expected in structural column cap applications without unnecessary added weight.
• No-coating finish - suitable for applications where the connector will be field-welded or integrated into assemblies with their own protective treatment or interior conditions.

Why This Product

• Faster installation without sacrificing structural integrity - the SDS screw fastening system eliminates the need to bore through-bolt holes in the field, reducing labor time while still achieving a strong, load-rated beam-to-column connection.
• Engineered specifically for steel column applications - the field-weld attachment method is purpose-built for steel columns and posts, making this cap a direct fit for structural framing projects that require a reliable connector at the column top.
• Versatile across column cap configurations - compatible with end condition accessories and available in custom sizes, this cap adapts to varied framing layouts without requiring a completely different product family.
• Made in the United States by Simpson - backed by a brand widely recognized in structural connector hardware, giving contractors and builders confidence in the quality and consistency of each component.

Frequently Asked Questions

How is the CCOQ3-SDS2.5 attached to a steel column?

The CCOQ3-SDS2.5 features a legless design that is intended for field-welded attachment to steel columns and posts. This approach allows for a streamlined, low-profile installation directly on top of the column.

What fasteners are used with this column cap?

This column cap is paired with Strong-Drive SDS Heavy-Duty Connector screws. These screws provide a lower profile than standard through bolts and engage a greater net section area of the column compared to standard bolt attachments, while also enabling fast installation.

What beam width is this column cap designed to accommodate?

The CCOQ3-SDS2.5 is designed for a beam width of 3-1/8 in. The cap measures 11 in. in length and 7 in. in height, and is constructed from 7 gauge material.

Does this column cap come with a protective coating or finish?

No, the CCOQ3-SDS2.5 has no coating finish applied. It is suitable for applications where a finish coating will be applied on-site after installation, or where no coating is required for the specific application.
