Anucha Metals is a well-known Stainless Steel 301 Nuts supplier in Bangkok, Thailand, offering fastening solutions where high tensile strength and flexibility are necessary. SS 301 is recognized for its work-hardening characteristic that enables it to achieve high tensile properties following cold working. We provide different kinds of SS 301 nuts such as hex, heavy hex, nyloc, and flange nuts, all manufactured under international standards like ASTM A276 and DIN specifications. These nuts are best suited for dynamic-load requirements, particularly where mechanical strength and corrosion resistance are significant considerations.
SS 301 has 16–18% chromium and 6–8% nickel content and tensile strength from 520–1380 MPa based on cold work. It has high fatigue strength, is not magnetic when annealed, but becomes magnetic on cold-working. SS 301 has medium corrosion resistance, tolerable in dry or mildly corrosive environments. The nuts have high ductility and are best suited for forming and high-load mechanical use.

Chanchai Stainless is dedicated to providing stainless steel 301 nuts with reliable performance, as validated by an array of tests like hardness testing, spectro analysis, PMI, and flaring tests. In addition, we conduct micro and macro tests, pitting resistance, and IGC tests for the quality assurance of each material delivered. Besides our strict testing procedures, we offer full documentation, including commercial invoices, packaging lists showing net and gross weights, box numbers, and labels. With our legalized or attested Certificate of Origin, combined with Third-Party Inspection Certificates, a complete guarantee of our effort to provide quality products and satisfactory customers is given.
SS 301 nuts find applications in aerospace, railways, construction structures, elevators, industrial robots, and mechanical enclosures. They are appropriate for vibration-exposed conditions like transport equipment and machine assemblies due to their high fatigue strength. They are also extensively applied in electrical panels, switchgear, and mechanical brackets where there is a need for strength and dimensional stability. SS 301 nuts are best employed in fastening stressed components, particularly in cases of repetitive or cyclic loading.
