An SS (stainless steel) dome nut, also called an acorn nut or cap nut, is a fastener with a rounded, closed-end top that covers the end of a bolt or stud. It provides a clean, decorative finish, protects threads from damage and corrosion, and enhances safety by preventing injury from sharp, exposed ends. Made from corrosion-resistant stainless steel (often grades like SS304 or SS316), these nuts are ideal for outdoor, marine, automotive, and furniture applications where both aesthetics and durability are important.
