What are the best fasteners for assembling stainless steel outdoor benches?

When assembling stainless steel outdoor benches, choosing the right fasteners is crucial for durability and longevity. The best options include corrosion-resistant stainless steel screws, bolts, and nuts, which resist rust and weathering. For added strength, consider using galvanized or coated fasteners, though stainless steel remains the top choice for seamless compatibility. Rivets and welding can also provide permanent solutions for heavy-duty benches. Always ensure the fasteners match the bench's material to prevent galvanic corrosion. Proper installation and periodic maintenance will further extend the life of your outdoor furniture.
