The Simpson Strong-Tie CC3 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 3-1/8" beam width and a 6x post, this column cap features an extended seat that provides additional bearing surface area beyond each side of the column, effectively distributing load from the beam and maximizing connection support. Built to perform in demanding structural environments, the CC3 1/4-6HDG is manufactured in the United States and meets rigorous standards for strength and load performance.

Frequently Asked Questions

What beam width and post size is the CC3 1/4-6HDG designed for?

The CC3 1/4-6HDG is engineered specifically for use with a 3-1/8" beam width and a 6x post. The W1 dimension is 3-1/4 in., the W2 dimension is 5-1/2 in., and the overall L dimension is 11 in., with an H1 dimension of 6-1/2 in.

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

The hot-dip galvanized finish provides corrosion resistance, making the CC3 1/4-6HDG suitable for use in exposed conditions or applications involving treated lumber, where standard finishes may degrade over time.

What is the purpose of the extended seat design on this column cap?

The extended seat design provides additional bearing surface area beyond each side of the column, which helps distribute load from the beam more effectively and maximizes connection support in structural post and beam assemblies.

Does the CC3 1/4-6HDG meet recognized structural and code standards?

Yes. The CC3 1/4-6HDG features certified welds, bolt spacing that meets NDS code requirements, and increased uplift load ratings suited for earthquake or wind loading conditions, making it appropriate for demanding structural wood-frame construction applications.
