What are the best fasteners for assembling stainless steel outdoor sofas?
When assembling stainless steel outdoor sofas, selecting the right fasteners is crucial for durability and weather resistance. The best options include stainless steel screws, bolts, and rivets, which resist rust and corrosion. Marine-grade stainless steel (such as 304 or 316) is ideal for outdoor use due to its high resistance to moisture and salt. Nylon-insert lock nuts or washers can prevent loosening over time. Avoid regular steel or zinc-plated fasteners, as they may corrode quickly. For a seamless look, consider hidden fasteners or adhesive solutions designed for metal furniture. Always pre-drill holes to prevent material stress and ensure a secure fit.
