AXWHYS 4x4 Pergola Post Brackets 2‑Pack (fits 3.6" x 3.6") — Black Powder‑Coated Steel, Includes Screws & Drill Bit

AXWHYS 2-pack 4"x4" pergola brackets (actual fit 3.6" x 3.6") are heavy-duty, powder‑coated steel corner supports designed to fasten and protect outdoor pergola posts quickly and securely.

These brackets are engineered from Q235B carbon steel with a durable black powder-coat finish for corrosion resistance and long outdoor life. Each kit includes two right-angle corner brackets, a masonry drill bit, and 46 Phillips self-tapping screws so you have everything needed to anchor posts without hunting for extras. Thoughtful details—raised drainage bases and internal baffles—reduce water pooling and simplify alignment during installation.

How do these pergola brackets make installation faster and easier?

The brackets come pre-drilled and include the screws and a drill bit to get you started right away, eliminating multiple trips to the hardware store. Baffles inside the three-sided corner design let you seat the post without measuring both wood faces for a flush fit.

• Pre-drilled hole pattern for straightforward screw placement
• Includes 46 Phillips head self-tapping screws and a drill bit
• Internal baffles reduce measuring and help align posts
• Raised bottom allows drainage to avoid water buildup

Will these brackets hold up to outdoor weather and weight?

Constructed from Q235B steel and finished with a black powder coat, the brackets resist rust and stay structurally sound in typical outdoor conditions. They are built to support common pergola assemblies, gazebo corners, and other outdoor timber joints when used with appropriate post sizes and fasteners.

• Q235B steel provides solid structural strength
• Black powder coat protects against corrosion and fading
• Raised base design reduces rot risk by shedding water
• Designed for 4x4 posts with actual interior fit around 3.6" x 3.6"

What sizes and applications are these brackets suitable for?

Although labeled 4"x4", the internal fit measures about 3.6" x 3.6", so they pair best with nominal 4x4 posts that match that actual timber dimension. They are versatile for decks, pergolas, gazebos, balconies, treehouses and other outdoor frame work where a 90° corner bracket is needed.

• Actual post fit: approximately 3.6" x 3.6" inside dimensions
• Common uses: pergolas, gazebos, railings, playhouses, cabins
• Works on wood-to-wood and wood-to-concrete installations (use proper anchors)
• Sold as a 2-piece kit with hardware for two post corners

Who is this for? DIYers, contractors, and outdoor-living renovators who want a ready-to-install bracket that reduces measuring, includes necessary fasteners, and helps prolong post life. If you’re building or repairing a pergola, gazebo, or similar outdoor structure using standard 4x4 posts and you need a neat, durable corner solution, this AXWHYS bracket set streamlines the job while protecting timber from trapped moisture.
