The Simpson 6X Beam Column Cap with SDS Screws HDH Quick-Install is a hot-dip galvanized structural connector engineered to create strong, reliable column-to-beam connections on top of steel columns. Built from 7-gauge steel and finished with a hot-dip galvanized coating for corrosion resistance, this column cap features a no-leg design that allows for direct field-welded attachment to steel columns and posts - eliminating traditional leg-style mounting and keeping the installation process efficient. Sixteen 1/4 in. x 2-1/2 in. Strong-Drive SDS Heavy-Duty Connector Screws are included, delivering fast, high-performance fastening that outpaces conventional bolt-based methods. Designed for 6X nominal lumber beam connections and structural framing applications where dependable load distribution from beam to column is essential, this cap is a practical solution wherever a low-profile fastening approach is preferred over through bolts.

Key Features

• No-leg design - enables direct field-welded attachment to steel columns and posts, streamlining on-site installation and eliminating the need for traditional leg-style hardware
• Extended seat configuration - distributes beam loads across a greater bearing surface, providing enhanced structural support that extends beyond each side of the column
• Includes 16 Strong-Drive SDS Heavy-Duty Connector Screws - delivers faster installation compared to traditional through-bolt methods, with no pre-drilling required and strong fastening performance right out of the box
• Hot-dip galvanized 7-gauge steel construction - provides corrosion resistance suited for structural framing applications where long-term durability and weather exposure are concerns
• Compatible with 6X nominal lumber beam sizes - fits beams at 5-1/4 in. and 5-1/2 in. widths, giving builders flexibility across common dimensional lumber and engineered beam applications
• Made in the United States - supports consistent quality and manufacturing standards for critical structural connections

Why This Product

• A complete, ready-to-install connection solution - the cap ships with all 16 fasteners needed for a full installation, so builders can move straight to work without sourcing additional hardware separately
• Simplified steel column attachment - the no-leg, field-weld design removes the complexity of traditional leg-style column caps, making it well suited for steel post and column applications common in post-frame, commercial, and heavy structural builds
• Corrosion-resistant finish for lasting performance - the hot-dip galvanized coating addresses the durability demands of outdoor and exposed structural framing, making it a practical choice for projects requiring corrosion-resistant hardware at beam-to-column connections
• Screw-based fastening over through bolts - the included Strong-Drive SDS Heavy-Duty Connector Screws offer a low-profile fastening alternative that reduces installation time and labor compared to traditional bolt attachment methods

Frequently Asked Questions

How does the CCOQ6-SDS2.5HDG attach to a steel column?

The CCOQ6-SDS2.5HDG features a no-leg design that allows for direct field-welded attachment to steel columns and posts, eliminating the need for traditional leg-style mounting and streamlining the installation process.

What fasteners are included, and why are they preferred over standard bolts?

The connector includes Strong-Drive SDS Heavy-Duty Connector screws. These screws offer several advantages over standard through bolts: they provide a lower profile, allow for faster installation, and engage a larger net section area of the column compared to standard bolt attachment.

How does the extended seat design improve load performance?

The extended seat bearing surface distributes beam loads beyond each side of the column, providing enhanced load transfer and improved support compared to a standard seat design.

What material and finish does the CCOQ6-SDS2.5HDG use, and is it suitable for demanding environments?

The CCOQ6-SDS2.5HDG is manufactured from 7-gauge steel and finished with a hot-dip galvanized coating, which provides corrosion resistance making it well suited for demanding or exposed environments.
