Andre Stainless is a reliable manufacturer and supplier of Stainless Steel 301 Bolts in Pulau Ujong, Singapore. SS 301 bolts are well-known for their high tensile strength, work-hardening ability, and resistance to corrosion in mildly aggressive environments. These bolts are great for applications that need strength, flexibility, and light weight. Made to meet international standards, our bolts come in various sizes and thread types for automotive, aerospace, and structural use. Andre Stainless guarantees precision-engineered SS 301 bolts with consistent performance and high fatigue resistance, meeting the fastening needs of mechanical and architectural projects across Singapore.
Stainless Steel 301 contains 16–18% chromium and 6–8% nickel. It offers a tensile strength of up to 930 MPa and a yield strength starting at 275 MPa (annealed). The alloy quickly work-hardens during forming, increasing strength. SS 301 is non-magnetic when annealed but becomes magnetic with cold working. It provides moderate corrosion resistance and high fatigue strength. These traits make SS 301 bolts suitable for structural, mechanical, and vibration-affected applications. The alloy performs well in environments that require light weight and durability, making it a preferred choice for dynamic fastening systems.

After the manufacturing, our quality control team will carry out a number of destructive and non-destructive tests using sophisticated methods and techniques to make sure the performance and reliability of our Stainless Steel 301 Bolts. Once all those test procedures are finished, we pack the bolts in a safe, high-end packaging material to avoid damage during transit. We ensure that there will be no delay and that the clients are receiving the products on schedule that has been agreed upon. We also provide all the documentation needed to make the delivery transparent and give the customer assurance about the quality of the product.
Stainless Steel 301 Bolts are often used in transportation systems, railway coaches, aerospace assemblies, and mechanical frameworks. Their ability to work-harden and resist fatigue makes them ideal for fastening systems under vibration and movement. SS 301 bolts are also used in electronic enclosures, conveyor systems, elevator parts, and vehicle body panels. Their moderate corrosion resistance makes them suitable for dry indoor or slightly corrosive industrial settings. Andre Stainless supplies these bolts in various head styles, threading options, and custom finishes, ensuring reliability and strength in both commercial and industrial applications throughout Pulau Ujong and Singapore.
