By combining technical expertise with customer-focused service, Lina Fasteners supports automotive, power generation, industrial, and engineering sectors with durable fastening solutions.
Stainless Steel 409 Stud Bolts are manufactured from a ferritic stainless steel alloy containing approximately 10.5–11.75% chromium, with small additions of titanium for stabilization. This composition provides good resistance to oxidation and mild corrosion, especially at elevated temperatures. Mechanically, 409 Stud Bolts offer moderate tensile and yield strength, good formability, and stable performance under thermal cycling. While not intended for highly corrosive environments, they deliver dependable mechanical strength and resistance to scaling, making them suitable for applications involving heat exposure and moderate stress.

Stainless Steel 409 Stud Bolts are widely used in applications where resistance to heat and oxidation is more critical than high corrosion resistance. They are commonly applied in automotive exhaust systems, manifolds, and emission control components. In power generation and industrial heating systems, these stud bolts are used in boilers, furnaces, and heat exchangers. Stainless Steel 409 Stud Bolts are also suitable for structural assemblies, brackets, and machinery components operating in mildly corrosive environments. Their cost-effective performance and thermal stability make them a practical choice for high-temperature and industrial fastening applications.
We prioritize quality and rigorously test all our products before shipping. These include hardness testing, chemical analysis (spectroanalysis), PMI testing, micro-macro testing, pitting resistance testing, fire testing, and intergranular corrosion testing. We provide complete documentation, such as commercial invoices with HS codes, packaging lists with loads, labels and numbers, and departure certificates. In addition, we provide third-party review certifications to ensure 100% customer satisfaction.
