At Mitchell Stainless in Hamilton, New Zealand, we supply high-quality stainless steel fasteners designed for strength, durability, and corrosion resistance. Our Stainless Steel 304 Nuts are made from austenitic stainless steel, offering excellent resistance to oxidation and general corrosion. Ideal for structural, industrial, and light engineering applications, these nuts provide secure fastening and long-term reliability in indoor, outdoor, and mildly corrosive environments. Supported by Mitchell Stainless’ commitment to quality and local expertise, 304 nuts are a trusted choice for customers seeking dependable, corrosion-resistant fasteners suitable for a wide range of applications.
Stainless Steel 304 Nuts are manufactured from an austenitic stainless steel alloy containing chromium and nickel. This composition provides good tensile strength, toughness, and excellent corrosion resistance across a variety of environments. The nuts maintain dimensional stability and mechanical performance under normal load conditions and resist oxidation and wear over time. Stainless Steel 304 remains non-magnetic in the annealed condition and offers reliable strength and durability, making it suitable for fastening applications in industrial, structural, marine, and general-purpose environments.
