The Simpson Strong-Tie CCOQ8-SDS2.5HDG is an 8x beam column cap engineered to deliver strong, reliable column-to-beam connections on top of steel columns. This column cap features a legless design that allows for field-welded attachment to steel columns and posts, providing a secure and structurally sound connection. The extended seat of the cap provides additional surface area for bearing that extends beyond each side of the column, helping to distribute load from the beam and provide critical support for the connection. Finished in Hot Dip Galvanized (HDG) coating and driven by Strong-Drive SDS Heavy-Duty Connector screws, this cap is built for demanding structural applications where performance and durability are essential.

Key Features

• Legless design enables field-welded attachment to steel columns and posts
• Extended seat provides additional bearing surface area beyond each side of the column for improved load distribution
• Strong-Drive SDS Heavy-Duty Connector screws deliver fast installation and attach to a greater net section area of the column than a standard bolt attachment
• SDS screws provide a lower profile than standard through bolts
• Diamond holes allow for temporary positioning during installation
• Hot Dip Galvanized finish for corrosion resistance
• Manufactured in the United States

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.
