What are the best fasteners for assembling granite outdoor flower boxes?

When assembling granite outdoor flower boxes, choosing the right fasteners is crucial for durability and stability. The best options include stainless steel screws, which resist rust and corrosion, and weather-resistant hardware like galvanized or coated brackets. Avoid standard steel fasteners, as they can deteriorate quickly in outdoor conditions. For added strength, use masonry anchors or epoxy adhesives to secure granite pieces. These materials ensure your flower boxes withstand the elements while maintaining a polished, long-lasting appearance in your garden.
