Andre Stainless is a reliable producer and exporter of Stainless Steel Nuts in Pulau Ujong, Singapore. Our products consist of hex nuts, lock nuts, dome nuts, wing nuts, etc., all of which are made from corrosion-resistant stainless steel grades such as 304, 316, and 321. Our nuts are produced to ASTM, DIN, and ISO standards and are of use in industrial, construction, marine, and hygienic applications. With dimensional precision, strength, and surface finish to a high standard, Andre Stainless offers fastening solutions that guarantee structural durability and reliability even in aggressive and high-vibration applications.
Stainless Steel Nuts are manufactured from SS 304, SS 316, or duplex stainless steel with tensile strengths of 515–620 MPa. SS 316 nuts contain molybdenum for increased pitting resistance. These nuts have great fatigue resistance, corrosion resistance, and durability in fluctuating mechanical loads. Thread accuracy and surface hardness provide dependable torque and long-term stability in bolted connections. They sustain strength in high-humidity or saltwater conditions and can withstand high temperatures and are recommended for use in outside and industrial applications.

In addition to our comprehensive testing procedures, we ensure full documentation, commercial invoices, packaging lists detailing net and gross weights, box numbers, and labels, besides a legalized or attested Certificate of Origin complemented by Third-Party Inspection Certificates, which gives complete assurance to the purchaser of our absolute commitment for superior products and unmatched customer satisfaction.
Yes, stainless steel nuts can be welded, but the process requires proper preparation and equipment. Ensuring the right welding method and parameters is key to maintaining their strength and corrosion resistance.
Yes, we provide ss nuts standard and customized dimensions and polishes to meet your specific project requirements. For more details mail us on sales@andrestainless.com
Stainless steel nuts can be magnetic depending on the grade. Austenitic stainless steels (e.g., 304, 316) are typically non-magnetic, while ferritic and martensitic grades (e.g., 430, 410) are magnetic.
Yes, stainless steel nuts can be used for underground applications due to their corrosion resistance. However, the specific grade chosen should be suitable for the environmental conditions, such as moisture and soil composition.
Stainless Steel Nuts are critical fastening elements in oil & gas, automotive, marine, construction, and food processing industries. Combined with washers and bolts, they form tough, corrosion-resistant structural joints in frames, machinery, pipelines, and tanks. In sanitary environments like dairy and pharmaceuticals, stainless steel nuts ensure cleanliness and withstand frequent washdowns. Their corrosion resistance makes them the best choice for offshore rigs, boat fittings, and chemical processing equipment. Andre Stainless nuts provide safety, strength, and reliability under harsh operating conditions, from mechanical assemblies to architectural installations.
