You’ll see a few names used for these parts. Most listings call them flat metal brackets, but they’re also commonly labeled as mending plates, straight braces, repair plates, or joining/connecting plates. The name often changes with the shape:

• Straight plates: simple flat strips for joining pieces end-to-end.
• L plates: flat right-angle plates for corners.
• T plates or square plates: for three-way or wider connections.

Regardless of the label, they serve a similar purpose—reinforcing or joining materials while staying flush. On Walmart, you can filter by shape, size, material, and finish to quickly find the style that fits your project.

Picking size depends on the joint you’re reinforcing and the space you have. A simple approach:

1. Measure the span: Choose a plate long enough to cover the joint with at least one screw hole on each side, ideally more for stability.
2. Check width and thickness: Wider/thicker brackets can handle heavier-duty projects; slimmer plates suit light repairs.
3. Review hole pattern: Make sure holes won’t be too close to edges and match the screw size you plan to use.
4. Confirm clearance: Ensure the length won’t interfere with hinges, drawers, or trim.

Product pages list dimensions and hole spacing, which can help you compare. When space allows, stepping up to a slightly longer plate can offer more mounting options.

Flat metal brackets are go-to hardware for strengthening and connecting pieces without adding bulk. Common uses include:

• Furniture repair: reinforcing wobbly joints, fixing cracked frames, and bracing tabletops or drawer bottoms.
• Shelves and cabinets: tying shelves to supports, or adding hidden reinforcement underneath.
• Woodworking projects: joining boards edge-to-edge, building crates or frames, and stiffening long seams.
• Appliance mounting: fixing and supporting panels, like securing a dishwasher to adjacent cabinetry (with the appropriate plate).
• Metalwork: connecting light-gauge metal parts when holes align.

The right plate—straight, L, T, or square—can make a quick, clean repair. Load capacity varies by material, size, and fasteners, so it’s a good idea to match the bracket to your project’s demands.

Focus on matching the bracket to your material, environment, and joint.

• Material: Stainless steel is a solid pick for moisture-prone or outdoor areas; zinc-plated steel is common for indoor use; powder-coated finishes add a clean look.
• Shape: Use straight plates for seams, L plates for corners, T plates for three-way joints, and square plates for wider reinforcement.
• Size & thickness: Longer and thicker plates generally support heavier-duty tasks; check listed dimensions.
• Hole pattern: Ensure hole count and spacing work with your screws and avoid edge split-out.

Filters on the product page can help you narrow by size, finish, and hole count before you compare options.

Installation is usually straightforward and can vary by material. A general approach:

1. Position and mark: Dry-fit the plate so holes sit fully on each side of the joint; mark centers.
2. Pre-drill: For wood, drill pilot holes sized for your screws to help reduce splitting. For thin metal, use compatible self-tapping screws when appropriate.
3. Fasten: Keep the bracket flush and drive screws snugly without over-tightening. Washers can help if holes are oversized.
4. Check alignment: Verify nothing binds (drawers, doors) and add a second plate if the span or load suggests it.

Results can vary by substrate and load, so refer to product details and use suitable safety gear and tools.
