Simpson Strong Tie ABA66Z Standoff Post Base 6x6

Product Description

The SIMPSON STRONG TIE ABA66Z is a 6x6 standoff post base designed to elevate wooden posts off concrete surfaces, maintaining a 1-inch air gap that reduces moisture contact and slows rot. Fabricated from 14-gauge galvanized Z-Max steel, this post base delivers corrosion resistance suited to outdoor and exposed environments. It installs with eight 16D hot-dipped galvanized nails and accepts a 5/8-inch diameter threaded anchor for secure attachment to a concrete footing. Licensed contractors and experienced builders rely on this hardware for structural deck, fence, and similar load-bearing post applications where long-term moisture management is a priority.

The ABA66Z is intended for use with 6x6 lumber posts in residential and light commercial construction. Typical applications include deck framing, pergolas, fences, carports, and other outdoor structures where posts are set on concrete piers or slabs. The standoff design keeps the post end grain separated from the concrete surface, allowing air circulation on all sides of the base. Where input data names specific compatible models or systems, they would be listed here; this unit is compatible with standard 6x6 nominal lumber and standard 5/8-inch anchor bolt hardware.

Key Features

• 14-gauge Z-Max galvanized steel construction for corrosion resistance in outdoor environments
• 1-inch standoff gap between post base and concrete surface promotes air circulation and reduces rot risk
• Accepts 5/8-inch diameter threaded anchor for positive connection to concrete footings
• Installs with eight 16D hot-dipped galvanized nails for a secure, code-compatible fastening pattern
• Sized for 6x6 nominal lumber posts

Compatibility

Designed as an OEM-style structural connector for 6x6 nominal lumber posts used in residential and light commercial deck, fence, pergola, and outdoor framing applications.

Installation Notes

Installation is typically performed by a licensed contractor or structural carpenter in accordance with applicable building codes. Anchor the base plate to the cured concrete footing using the specified 5/8-inch threaded anchor before setting the post. Use hot-dipped galvanized or stainless fasteners throughout to match the corrosion resistance of the base hardware. Verify local building department requirements for post base connections, as deck and structural framing work commonly requires inspection.
