Simpson Strong Tie APB66 6x6 Black Steel Post Base

Product Description

The SIMPSON STRONG TIE APB66 is a 6-inch by 6-inch post base fabricated from galvanized steel with a black powder-coat finish. It anchors structural posts to concrete or treated lumber bases, transferring vertical and lateral loads to the foundation. The powder-coat layer provides corrosion resistance for exterior and exposed applications. Licensed contractors and experienced framers install this hardware on decks, pergolas, carports, and similar outdoor structures where a clean, finished appearance is required alongside structural performance. The APB66 is engineered to meet demanding building code requirements, including provisions for seismic and high-wind load conditions.

The APB66 is used in residential and light commercial outdoor construction where 6-inch by 6-inch posts require a secure, code-compliant base connection. Typical applications include deck framing, pergola columns, covered patios, and fence post installations. It is suited for ground-level and elevated installations where moisture exposure and environmental loading are primary concerns. For a finished installation, the manufacturer recommends pairing with Outdoor Accents structural screws and hex head washers, sold separately.

Designed for use with 6-inch by 6-inch nominal dimensional lumber posts in outdoor structural applications. For a coordinated installation, the manufacturer recommends pairing with Outdoor Accents structural screws and hex head washers, available separately.

Installation Notes

Installation should be performed by a licensed contractor or qualified framer familiar with structural connector hardware and local building codes. Anchor the base to the concrete footing or treated lumber before setting the post, following the fastener schedule specified on the product drawing. Verify that the installation meets local IRC, IBC, or applicable regional code requirements for post base connections, especially in seismic or high-wind zones. Do not substitute fastener types or quantities, as the load rating depends on the specified fastener pattern.
