At Hazlewood Fasteners in Canberra, we engineer fasteners that thrive under pressure and heat. Our stainless steel 409 stud bolts are designed for demanding environments where corrosion, vibration, and thermal stress are constant challenges. Crafted from a ferritic, titanium-stabilized stainless steel, these stud bolts combine reliable strength with oxidation resistance, ensuring long-term performance in automotive, industrial, and structural applications. Hazlewood Fasteners’ 409 stud bolts are more than connectors—they are the backbone of durability and precision, maintaining tight, secure assemblies that stand up to time, temperature, and the harshest conditions modern engineering can deliver.
Stainless steel 409 stud bolts are manufactured from a ferritic chromium stainless steel alloy stabilized with titanium, enhancing corrosion resistance and weldability. The ferritic structure offers good mechanical strength, fatigue resistance, and dimensional stability under thermal cycling. These stud bolts maintain oxidation resistance up to 675°C, resisting scaling and thermal degradation. With moderate tensile strength, excellent ductility, and resistance to stress relaxation, 409 stud bolts provide dependable performance in high-temperature and mildly corrosive environments, making them a cost-effective solution for reliable, long-lasting fastening under challenging conditions.

Stainless steel 409 stud bolts excel in high-heat and vibration-prone applications where corrosion resistance is critical. They are widely used in automotive exhaust systems, mufflers, catalytic converters, heat exchangers, and industrial machinery. Their stability under thermal cycling makes them ideal for welded assemblies and heavy-duty structural components exposed to fluctuating temperatures. In construction, fabrication, and light industrial projects, 409 stud bolts provide secure, vibration-resistant fastening. Hazlewood Fasteners’ 409 stud bolts deliver enduring strength, ensuring every connection remains tight, balanced, and protected—holding assemblies together with precision and resilience where reliability cannot be compromised.
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.
