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

When assembling stainless steel outdoor armchairs, choosing the right fasteners is crucial for durability and weather resistance. The best options include stainless steel screws, bolts, and rivets, which resist corrosion and withstand harsh outdoor conditions. Avoid galvanized or carbon steel fasteners, as they can rust and weaken over time. For added strength, consider using nylon-insert lock nuts or thread-locking adhesives to prevent loosening. Always ensure the fasteners match the chair's design and load requirements for a secure and long-lasting assembly.
