The Simpson PB66HDG 6x6 Hot-Dip Galvanized Post Base from Simpson Strong-Tie is a heavy-duty structural connector engineered to create a secure, reliable connection between a 6x6 post or column and its supporting foundation. Built from 12-gauge steel with a hot-dip galvanized coating, this post base is purpose-designed for top-supported applications such as deck post-to-foundation connections, patio cover column bases, and structural post installations where long-term durability and load-carrying performance are essential.

Key Features

• Hot-dip galvanized coating - delivers enhanced corrosion resistance for outdoor environments and direct contact with treated wood, helping the connector hold up where moisture and chemical exposure are ongoing concerns.
• 12-gauge steel construction - provides the structural integrity and load capacity needed for demanding post-to-foundation applications without adding unnecessary bulk.
• Fastener flexibility - accommodates installation with either 0.162" x 3-1/2" nails or 1/2" bolts, giving contractors and builders options to match the fastener type to the specific structural requirement.
• Designed for top-supported structures only - correctly matched to deck posts, patio cover columns, and similar applications, keeping installations within the connector's engineered performance range.
• Domestic manufacturing - produced in the United States under Simpson Strong-Tie's quality standards, supporting consistent dimensional accuracy and reliable product performance.

Why This Product

• Built to withstand the outdoors - the hot-dip galvanized finish goes beyond standard coatings to protect against rust and corrosion in wet conditions and treated-lumber environments, making this a practical long-term choice for exterior structural connections.
• Trusted Simpson Strong-Tie engineering - this post base comes from a brand with a well-established reputation in structural connectors, giving builders confidence that the product meets the demands of real-world installation conditions.

Frequently Asked Questions

What types of fasteners can be used to install the PB66HDG?

The PB66HDG post base can be installed using either 0.162" x 3-1/2" nails or 1/2" bolts, giving installers flexibility depending on the application and structural requirements.

Is this post base suitable for outdoor or treated-wood applications?

Yes. The hot-dip galvanized coating on the PB66HDG provides extra corrosion resistance, making it well suited for outdoor use and applications involving treated wood where moisture and chemical exposure are a concern.

Can the PB66HDG be used for fences or unbraced carports?

No. Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations such as fences or unbraced carports. This connector is designed for top-supported structures only.

Is there a minimum sidecover requirement for this post base?

Yes. A 2" minimum sidecover is required in order to obtain the full rated load capacity of the PB66HDG post base.
