SS 347 Nuts

SS 347 Nuts are stabilized stainless steel fasteners designed for superior resistance to high temperatures, oxidation, and intergranular corrosion. Manufactured using niobium-stabilized austenitic stainless steel, these nuts maintain strength even during continuous exposure to elevated temperatures. Zeron Fasteners provides precision-engineered SS 347 Nuts in various types such as Hex Nuts, Lock Nuts, and Heavy Hex Nuts, ensuring reliable joint integrity in heat exchangers, chemical equipment, and power generation systems. Their durability and corrosion resistance make them a preferred choice for applications in aggressive and high-pressure environments.
