The Simpson Strong-Tie CCOQ7-SDS2.5 is a heavy-duty 7X beam column cap engineered to deliver strong, reliable column-to-beam connections on top of steel columns. Constructed from 3-gauge steel with no leg design, the CCOQ7-SDS2.5 is built for field-welded attachment directly to steel columns and posts. The generously sized seat extends beyond each side of the column to distribute beam loads effectively across a broader bearing surface. Rather than traditional through-bolt attachment, this column cap utilizes Strong-Drive SDS Heavy-Duty Connector screws, which engage a greater net section area of the column and streamline the installation process. Manufactured in the United States, this column cap is a dependable structural solution for demanding beam-to-column applications.

Key Features

• No-Leg Design: Enables field-welded attachment to steel columns and posts for a clean, secure fit.
• Extended Seat Bearing Surface: The seat extends beyond each side of the column, distributing load from the beam and providing additional support at the connection point.
• Strong-Drive SDS Heavy-Duty Connector Screws: Attach to a greater net section area of the column compared to standard bolt attachments.
• Lower Profile Fastening: SDS screws provide a lower profile than standard through bolts, resulting in a cleaner installation.
• Diamond Holes: Included for temporary fastening during installation.
• 3-Gauge Steel Construction: Provides heavy-duty structural performance suited for demanding load applications.
• Quick Installation: Strong-Drive SDS screws are designed for fast, efficient field installation.

Frequently Asked Questions

What type of columns is the CCOQ7-SDS2.5 designed to attach to?

The CCOQ7-SDS2.5 is designed for field-welded attachment directly to steel columns and posts. Its no-leg design enables a clean, secure fit when welded to steel column tops.

Why does the CCOQ7-SDS2.5 use SDS screws instead of traditional bolts?

The Strong-Drive SDS Heavy-Duty Connector screws engage a greater net section area of the column compared to standard bolt attachments. They also provide a lower profile than standard through bolts, resulting in a cleaner and more streamlined installation process.

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

The CCOQ7-SDS2.5 is constructed from 3-gauge steel, providing heavy-duty structural performance suited for demanding load applications.

What is the purpose of the extended seat on this column cap?

The seat of the CCOQ7-SDS2.5 extends beyond each side of the column to distribute beam loads more effectively across a broader bearing surface, providing additional support at the connection point.
