The Simpson 4x Beam, 8x Post HDG SDS Column Cap is built for column-to-beam connections in wood construction where strength, corrosion resistance, and fast installation are priorities. Designed to work with rough-cut lumber, this column cap pairs a heavy-gauge steel body with a Hot Dip Galvanized finish and comes ready to install with Strong-Drive SDS Heavy-Duty Connector screws included - making it a complete, field-ready solution for demanding structural applications.

Key Features

• Extended bearing seat - distributes beam loads across a greater surface area beyond each side of the column, reducing stress concentrations and reinforcing the overall connection
• Hot Dip Galvanized finish - provides robust corrosion resistance suited to exposed, outdoor, or high-moisture environments where long-term durability matters
• Compatible with rough-cut lumber - engineered specifically for rough-cut dimensional sizes rather than standard dressed lumber, giving builders flexibility for traditional or specialty framing applications
• Includes Strong-Drive SDS Heavy-Duty Connector screws - the lower-profile screw attachment engages a greater net section area of the column than a traditional bolt, improving connection performance without extra hardware procurement
• Supports earthquake and wind uplift resistance - approved for structures requiring enhanced uplift resistance, making it a practical choice for seismic and high-wind construction zones
• Made in the United States - domestic production supports consistent quality standards and reliable supply for professional building projects

Why This Product

• Everything needed is in the box - the column cap ships with the required Strong-Drive SDS screws already included, eliminating a separate fastener order and keeping installation moving on the job site
• Built for real-world structural demands - approved for column-to-beam connections in wood construction and for applications requiring enhanced uplift resistance under earthquake or wind loading, this cap is suited for projects where code compliance and structural integrity are non-negotiable
• Corrosion resistance without compromise - the Hot Dip Galvanized finish delivers lasting protection in outdoor and exposed settings, reducing long-term maintenance concerns for permanent structures
• Rough-cut lumber ready - unlike connectors sized only for dressed lumber, this cap is specifically engineered for rough-cut dimensional stock, making it the right fit for post-and-beam, timber frame, and similar construction styles without costly modifications

Frequently Asked Questions

What lumber sizes is the CCQ48-SDS2.5HDG designed to work with?

The CCQ48-SDS2.5HDG is designed for use with a 4x beam and an 8x post. It is specifically engineered for rough-cut lumber sizes, making it suitable for applications where rough-cut dimensional lumber is used rather than standard dressed lumber.

What type of fasteners are used with this column cap, and are they included?

This column cap is designed for use with Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws provide a lower profile than standard through bolts and attach to a greater net section area of the column than a traditional bolt attachment.

What finish does the CCQ48-SDS2.5HDG have, and why does it matter?

The CCQ48-SDS2.5HDG features a Hot Dip Galvanized finish, which provides corrosion resistance. This makes it well suited for exterior or exposed applications where moisture and environmental conditions could otherwise compromise the integrity of the connection over time.

Is this column cap suitable for structures in high-wind or seismic zones?

Yes. The CCQ48-SDS2.5HDG features increased uplift load capacity specifically intended to address earthquake and wind loading requirements, making it appropriate for structures in regions where enhanced uplift resistance is needed.
