The Simpson Strong-Tie CC5 1/4-6HDG Column Cap is a heavy-duty, hot-dip galvanized connector engineered to deliver strong, reliable column-to-beam connections in wood construction. Designed for use with a 5-1/8" beam width and a 6x post, this column cap features a load-distributing seat that extends beyond each side of the column, providing an additional surface area of bearing to effectively transfer loads from the beam down through the supporting post. With certified welds, increased uplift load ratings, and code-compliant bolt spacing, the CC5 1/4-6HDG is purpose-built for demanding structural applications where both performance and durability are required. Made in the United States, this connector reflects Simpson Strong-Tie's commitment to quality in structural hardware.

Key Features

• Certified Welds: Engineered welds provide confidence in strength and load-carrying capacity across the connection point.
• Increased Uplift Load Ratings: Uplift loads are increased to meet the demands of earthquake or high-wind loading scenarios.
• NDS Code-Compliant Bolt Spacing: Bolt hole spacing meets National Design Specification (NDS) code requirements to ensure optimal structural performance.
• Diamond Holes: Integrated diamond holes allow for quick and convenient temporary fastening during installation.
• Extended Bearing Seat: The seat of the column cap provides additional surface area of bearing that extends beyond each side of the column, helping to distribute beam loads effectively.
• Hot-Dip Galvanized Finish: The HDG finish delivers superior corrosion resistance, making this connector suitable for exposed or treated-lumber applications.
• Made in the United States: Manufactured domestically to consistent quality standards.

Frequently Asked Questions

What beam and post sizes is the CC5 1/4-6HDG designed to fit?

This column cap is specifically designed for use with a 5-1/8" beam width and a 6x post, making it suited for glulam or engineered lumber beams of that dimension paired with standard 6x lumber posts.

Why is hot-dip galvanizing used on this column cap?

Hot-dip galvanizing provides a heavy-duty corrosion-resistant coating, making the CC5 1/4-6HDG suitable for demanding structural applications where long-term durability and resistance to moisture or harsh environments are required.

Is this column cap suitable for high-wind or seismic applications?

Yes. The CC5 1/4-6HDG features increased uplift load ratings specifically designed to meet the demands of earthquake or high-wind loading scenarios, making it appropriate for structurally demanding environments.

Does this column cap meet code requirements for bolt spacing?

Yes. The bolt hole spacing on the CC5 1/4-6HDG meets National Design Specification (NDS) code requirements, ensuring optimal structural performance and compliance in permitted construction projects.
