A.A Trailer Corner Brackets 16-Pack — Zinc-Plated Heavy-Duty Steel, 8 Left/8 Right for Wood Stake Bodies 4" x 2.5"

A.A 16-piece utility trailer corner bracket kit securely joins wood panels at right angles for stake bodies, tailgates, racks, and gate connectors.

These corner brackets provide a simple, durable method to fasten two wooden panels together on utility trailers and similar cargo frames. Each kit contains eight left and eight right brackets sized for conventional stake-body assemblies. Constructed from heavy-duty steel with zinc plating, they resist corrosion while giving installers a consistent mounting footprint. Screws are not included to allow you to choose the fastener type and length that best fits your timber thickness and load needs.

How do these brackets connect wooden trailer panels?

The brackets wrap around the corner where two panels meet and are screwed directly into the wood on both faces to lock the boards at a 90° angle. Their pre-drilled holes line up for quick installation and ensure repeatable alignment across multiple corners.

• Kit includes 8 left and 8 right brackets for balanced assemblies.
• Each bracket measures 4" long by 2½" wide for common stake sizes.
• 5/16" diameter holes accept standard carriage or hex bolts, carriage bolts, or heavy screws.
• Designed for direct wood mounting — choose appropriate screws for board thickness.

Will these brackets resist weather and corrosion on outdoor trailers?

The brackets are made from heavy-duty steel and receive a zinc plating finish to slow oxidation and protect the metal in outdoor environments. While zinc plating improves rust resistance, routine inspection and touch-up are recommended in harsh coastal or salted-road conditions.

• Zinc-plated finish for basic weather and rust protection.
• Steel construction for structural support under typical trailer loads.
• Periodic maintenance extends service life—clean and recoat if surface wear appears.

What fasteners and tools do I need to install them properly?

Screws or bolts are not included so you can pick fasteners that match your wood thickness and expected loads. For most installations, heavy wood screws or 5/16" bolts with washers and nuts provide a secure hold; a power drill and basic hand tools are sufficient for mounting.

• Recommended: 5/16" bolts or heavy wood screws (length depends on board thickness).
• Required tools: drill/driver, appropriate drill bits, wrench or socket for bolts.
• Use washers to distribute load and prevent pull-through on softer woods.

How do I know if these brackets fit my trailer panels?

Check the bracket dimensions against your stake or panel thickness and the required screw pattern. Each bracket is 4" long and 2½" wide with 5/16" holes; they work well with common trailer stakes, tailgates, and rack members but may not suit oversized or specialty profiles.

• Bracket size: 4" length x 2½" width; hole diameter: 5/16".
• Best for standard wooden trailer panels, tailgates, and bulkhead corners.
• Measure your panels and choose screw length for secure penetration without splitting.

Who is this for: This 16-piece A.A bracket kit is made for trailer owners, small-fleet maintenance teams, and DIYers who need a reliable, repeatable corner connection for wooden stake bodies, gates, and racks. It’s suitable for repairs, refurbs, and new builds where corrosion-resistant hardware and straightforward installation are priorities. If you require stainless or custom-sized connectors for extreme environments, consider alternative finishes or custom fabrication.
