Product Description
The Simpson A66 5-7/8 in. x 5-7/8 in. x 1 1/2 in. Galvanized Angle is a 12-gauge steel connector from Simpson designed to reinforce 90 deg. connections across a broad range of structural and home repair applications. Its symmetrical profile helps ensure right-angle joints come together consistently straight and properly aligned, while its G90 zinc galvanized finish delivers extra resistance against corrosion - making it a dependable choice for outdoor builds and environments where moisture is a concern. Installed with 3/8 in. diameter bolts, the A66 provides a level of joint strength that angled nailing or screw fastening alone simply cannot match.
Key Features
- Versatile 90 deg. connector - handles a wide variety of structural connections and home repair projects, reducing the need for multiple specialized fasteners
- Stronger than angled nailing or screw fastening alone - distributes load across both joined members for greater structural integrity at every joint
- Promotes consistently straight, properly aligned corners - helps eliminate the guesswork of freehand fastening so finished assemblies meet square reliably
- Made from 12-gauge steel - provides the material thickness needed for demanding connections without unnecessary bulk
- G90 zinc galvanized finish - delivers extra corrosion resistance for outdoor projects and applications where moisture is present
Why This Product
- Engineered for real structural load - because the A66 is installed with 3/8 in. diameter bolts rather than relying on nails or screws alone, it creates a more secure, load-bearing right-angle connection suited to projects where joint integrity matters
- Built to resist the elements - the G90 zinc galvanized coating goes beyond basic rust protection, making this angle bracket a practical fit for decks, fences, outdoor framing, and other moisture-exposed applications
- Symmetrical design simplifies layout - equal 5-7/8 in. legs on both sides mean no guessing which face goes where, speeding up installation and helping ensure consistent results across multiple connection points
- Backed by Simpson quality and U.S. production - Simpson is a widely trusted name in structural connectors, and the A66 is built to the dimensional and material standards that contractors and serious DIYers rely on
