Weston Stainless, located in Midland, UK, is a reputable provider of stainless steel products of high quality, providing precision-engineered solutions for all industries. Their Stainless Steel 301 Fasteners are manufactured using AISI 301 stainless steel, a corrosion–resistant, high–strength austenitic grade exhibiting excellent durability and work-hardening characteristics. These fasteners come in different shapes and forms, such as bolts, nuts, screws, washers, and studs, and are best suited for use in the automotive, aerospace, construction, and industrial sectors. Made of high-grade stainless steel, they possess higher mechanical strength, good fatigue resistance, and consistent performance in high-stress and corrosive conditions.
Stainless Steel 301 Fasteners consist of 16-18% chromium, 6-8% nickel, 2% manganese, 1% silicon, 0.15% carbon, 0.045% phosphorus, and 0.03% sulfur, with good corrosion resistance and high tensile strength. The mechanical properties of Stainless Steel 301 Fasteners are a tensile strength of 520-1035 MPa, yield strength of 275-758 MPa, elongation of 40%, and hardness up to 41 HRC, making them suitable for applications involving high stress. The physical characteristics boast a density of 7.86 g/cm³, a melting point ranging from 1399-1421°C, and thermal conductivity of 16.3 W/m·K and thus suit demanding fastening and structural applications.

Stainless Steel 301 Fasteners find broad applications in high–strength, corrosion–resistance, and durability-needed industries. These are necessary for automotive, aerospace, construction, and railway sectors for component fastening that is subjected to vibration, stress, and harsh environments. They are the best choice for structural frameworks, bridges, machinery, and industrial equipment due to their superior mechanical characteristics. They also find application in marine, chemical processing, and food processing environments where resistance to chemicals and oxidation is of high importance. They possess high work-hardening ability, which keeps them strong when under pressure, making them well adapted to applications that are exposed to high temperature and wear.
Stainless Steel 301 Fasteners include Mill Test Certificates (MTC) EN 10204 3.1/3.2, third-party inspection reports, and conformity certificates to guarantee high quality and industry standards. They are safely packed in wooden crates, cartons, or poly bags with protective coatings to avoid damage and corrosion during shipping. Delivery is handled efficiently through air, sea, or land transport to ensure safe and timely delivery according to customer requirements and project needs.
