Anucha Metals is a trusted supplier of Stainless Steel 301 Fasteners in Bangkok, Thailand. SS 301 is recognized for its superior strength, high ductility, and corrosion and wear resistance, and therefore considered suitable for structural and heavy-load applications. Our assortment consists of hex bolts, machine screws, nuts, and anchors, manufactured according to international standards of quality like ASTM A276 and A193. We deliver both cold-worked fasteners and annealed fasteners to meet varying tensile needs, making them appropriate for aerospace, transportation, construction, and manufacturing assembly lines.
SS 301 has 16–18% chromium, 6–8% nickel, and negligible carbon content. It has tensile strength of 520–1380 MPa, depending on temper. The alloy is non-magnetic in the annealed condition and becomes magnetic when cold worked. SS 301 has good fatigue strength, moderate corrosion resistance, and good formability, suitable for spring-type applications and dynamic loads.

We pack and send our Stainless Steel 301 Fasteners with extra care so that they reach our customers in their best condition. Normally, the fasteners are packed inside waterproof material bags and put inside wooden boxes having reinforced strips on them for protection. Lifting points are fitted to these packages for easy handling during transportation. We also provide along with the shipment all the required documents like a commercial invoice, certificate of origin, fumigation certificate, heat treatment chart, quality assurance plan, and material testing certificates. We ensure the timely delivery of our products with perfect condition so that our customers get full satisfaction.
SS 301 is used for transportation equipment, aircraft components, railway equipment, elevators, and industrial fasteners with a requirement of high strength and resistance to impact or vibration. They are also employed in support brackets, clamps, and springs. The high fatigue strength of the alloy allows it to be used in mechanically stressed devices like conveyors, machinery enclosures, and robotic joints. SS 301 is selected where a combination of mechanical toughness and corrosion resistance is desired.
