The Simpson CC88HDG 8x Beam 8x Post Hot-Dip Galvanized Column Cap is a heavy-duty structural connector from Simpson engineered for reliable column-to-beam connections in post-and-beam wood construction. Built specifically for 8x8 post and 8x beam configurations, this column cap features a robust seat that extends beyond each side of the column, providing an expanded bearing surface that distributes load from the beam while delivering solid support at the connection point. With certified welds, increased uplift load capacity, and code-compliant bolt spacing, the CC88HDG is a dependable choice for timber framing applications where structural integrity is critical - from residential builds to commercial construction in high-wind or seismic zones.

Key Features

• Hot-dip galvanized finish - provides enhanced corrosion resistance for long-term performance in exposed outdoor environments and applications involving pressure-treated lumber
• Certified welds - gives buyers confidence in the connector's strength and load-handling integrity at every joint
• Increased uplift load capacity - makes this column cap well-suited for structures in earthquake or high-wind regions where uplift forces are a primary design concern
• Code-compliant bolt spacing - satisfies NDS requirements, simplifying inspection and approval for residential and commercial timber framing projects
• Extended seat bearing surface - distributes beam load evenly across the connection point, reducing concentrated stress and supporting long-term structural performance
• Compatible with standard 8x lumber - fits both rough-cut and standard-dimension 8x post and 8x beam material, offering versatility across common post-and-beam applications

Why This Product

• Purpose-built for 8x post-and-beam construction - the CC88HDG is sized and engineered specifically for 8x8 post and 8x beam configurations, meaning buyers get a connector that fits their application without modification or compromise
• Corrosion resistance where it counts - the hot-dip galvanized finish stands up to the demanding conditions of outdoor exposure and contact with pressure-treated lumber, reducing long-term maintenance concerns in vulnerable environments
• Designed for high-demand structural zones - increased uplift load capacity and certified welds make this connector a strong fit for seismic and high-wind applications where standard connectors may fall short
• Made in the United States - this column cap is a domestic product, which can matter to buyers prioritizing domestic manufacturing quality and supply consistency for their structural hardware

Frequently Asked Questions

What post and beam sizes is the CC88HDG compatible with?

The CC88HDG is designed specifically for 8x8 post and 8x beam configurations. Both the W1 and W2 dimensions are 7-1/2 in., confirming compatibility with standard 8x lumber dimensions.

Why is the hot-dip galvanized finish important for this column cap?

The hot-dip galvanized finish provides enhanced corrosion resistance, making the CC88HDG well-suited for use in exposed outdoor environments or applications where pressure-treated lumber is used, which can accelerate corrosion in connectors with lesser finishes.

Is the CC88HDG suitable for use in high-wind or seismic zones?

Yes. The CC88HDG features increased uplift load capacity, which is specifically intended to address the demands of earthquake or wind loading applications, making it appropriate for use in high-wind or seismic environments.

What bolt size does the CC88HDG require, and does it meet code requirements?

The CC88HDG uses 3/4 in. bolts, and its bolt spacing is designed to meet NDS code requirements to ensure optimal structural performance at the connection point.
