The Simpson 8X Beam Column Cap with SDS Screws HDG is a heavy-duty structural connector engineered for reliable column-to-beam connections on top of steel columns. Built by Simpson and finished in a Hot Dip Galvanized coating for lasting corrosion resistance, this cap uses a legless design that allows for field-welded attachment to steel columns and posts. Strong-Drive SDS Heavy-Duty Connector screws secure the beam connection, providing a low-profile fastening solution that performs in demanding structural framing applications without requiring through bolts.

Key Features

• Legless design - allows field-welded attachment directly to steel columns and posts, giving installers flexibility in the field without relying on pre-drilled leg hardware
• Extended seat beyond column edges - provides additional bearing surface that extends past each side of the column, helping to distribute beam load across a wider area for a more secure structural connection
• Hot Dip Galvanized finish - delivers heavy-duty corrosion protection suited to outdoor, exposed, or high-moisture structural environments where long-term durability is critical
• Strong-Drive SDS Heavy-Duty Connector screws included - eliminates the need for through bolts at the beam connection, simplifying installation while maintaining structural performance
• 3 gauge steel construction - provides the material thickness required for heavy structural framing applications where connection strength is a priority
• Fits 8x beams with a 7-1/2 in. beam width accommodation - ensures a precise fit for standard 8x dimensional lumber, reducing guesswork and fitting issues on the job site

Why This Product

• Weld-ready legless construction simplifies steel column connections - the legless design is specifically approved for field-welded attachment to steel columns and posts, making this cap a practical choice for structural framing projects that involve steel support members
• Screw-fastened beam attachment replaces through bolts - the use of Strong-Drive SDS Heavy-Duty Connector screws at the beam provides a cleaner, faster installation compared to through-bolt alternatives, without sacrificing connection integrity
• Hot Dip Galvanized coating for long-term performance - the HDG finish is suited to applications where exposure to the elements is a concern, helping protect the connection hardware over the life of the structure
• American-made quality from a trusted structural connector brand - produced by Simpson and made in the United States, this column cap reflects the manufacturing standards expected in professional structural framing work

Frequently Asked Questions

What beam size is the CCOQ8-SDS2.5HDG designed to fit?

This column cap is designed for use with 8x beams, featuring a beam width accommodation of 7-1/2 in. The cap measures 11 in. in length and 7 in. in height, making it specifically suited to structural applications involving 8x lumber beams.

How does this column cap attach to a steel column?

The CCOQ8-SDS2.5HDG features a legless design that allows it to be field-welded directly to steel columns and posts. The beam portion of the connection is then secured using Strong-Drive SDS Heavy-Duty Connector screws, which attach to a greater net section area of the column than a standard bolt attachment and provide a lower profile than standard through bolts.

What type of finish does this column cap have, and is it suitable for exposed or outdoor applications?

This column cap is finished with a Hot Dip Galvanized (HDG) coating, which provides corrosion resistance. This makes it well suited for demanding structural applications where exposure to moisture or the elements is a concern.

What material gauge is used in the construction of this column cap?

The CCOQ8-SDS2.5HDG is constructed from 3 gauge steel, which is a heavy-duty material thickness appropriate for demanding structural column-to-beam connection applications.
