The Simpson CC46HDG CC Hot-Dip Galvanized Column Cap is engineered by Simpson to deliver strong, reliable column-to-beam connections in wood construction. Designed for use with a nominal 4x beam and a nominal 6x post, this column cap features a seat that provides additional surface area of bearing extending beyond each side of the column, helping to distribute load from the beam evenly and provide solid support for the connection. Built from 7-gauge steel with a hot-dip galvanized finish, it is well suited for exterior installations and treated-wood applications where long-term corrosion resistance is essential.

Key Features

• Certified welds - give you confidence in the strength and load performance of every connection
• Increased uplift load capacity - engineered to handle higher uplift forces caused by earthquake or wind loading, adding a critical layer of structural reliability
• Bolt spacing that meets NDS code requirements - ensures optimal performance and simplifies compliance on permitted projects
• Diamond holes - allow for temporary fastening during installation, making positioning faster and easier before final bolting
• 7-gauge steel construction - provides heavy-duty strength appropriate for demanding structural column-to-beam applications
• Hot-dip galvanized finish - delivers extra corrosion resistance, making this cap a durable choice for exterior environments and contact with treated wood
• Installs with six 5/8-in. diameter HDG bolts - hardware type is consistent with the galvanized coating, supporting corrosion resistance throughout the entire connection

Why This Product

• Built for tough exterior and treated-wood conditions - the hot-dip galvanization goes beyond standard coatings to resist moisture and chemical exposure, making this column cap a sound long-term investment in applications where corrosion is a real concern
• Engineered for code-compliant structural connections - certified welds and NDS-compliant bolt spacing mean the CC46HDG is designed to meet the requirements inspectors and engineers expect, reducing guesswork on the job site
• Designed to handle real-world loading events - increased uplift capacity for earthquake or wind loading makes this connector appropriate for regions with demanding structural requirements, not just everyday static loads
• Extended bearing seat for superior load distribution - the seat design transfers load from the beam across a wider surface area, reducing point stress on the post and supporting a more secure, balanced column-beam joint

Frequently Asked Questions

What beam and post sizes is the CC46HDG designed to fit?

The CC46HDG is designed for use with a nominal 4x beam width and a nominal 6x post size, making it suitable for standard dimensional lumber in those sizes used in wood construction.

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

Hot-dip galvanization (HDG) provides extra corrosion resistance, making the CC46HDG well-suited for exterior applications and installations involving treated wood, where standard finishes may degrade over time due to moisture or chemical exposure.

How does the CC46HDG help with load distribution?

The seat of the column cap provides an additional surface area of bearing that extends beyond each side of the column. This design helps distribute the load from the beam evenly and provides solid support for the column-to-beam connection.

What hardware is required to install the CC46HDG?

The CC46HDG is installed with (6) 5/8-in. diameter HDG bolts. The bolt spacing is designed to meet NDS code requirements to ensure optimal performance and structural integrity.
