At Hazlewood Fasteners in Canberra, we believe reliability begins with the smallest details. Our stainless steel 409 nuts are built to deliver dependable fastening performance in environments where heat, corrosion, and vibration challenge conventional materials. Crafted for strength and durability, these nuts combine corrosion resistance with excellent thermal stability—making them a trusted choice across automotive, structural, and industrial applications. Designed for resilience and value, Hazlewood Fasteners’ 409 nuts bring precision, endurance, and confidence to every assembly. They’re not just components—they’re the quiet assurance that your connections will hold strong, mile after mile, task after task.
Stainless steel 409 nuts are manufactured from a ferritic, titanium-stabilized alloy containing chromium for superior oxidation and corrosion resistance. Their composition provides excellent heat tolerance and moderate tensile strength, maintaining stability under continuous exposure to high temperatures. The titanium addition enhances structural integrity and minimizes scaling and brittleness during thermal cycling. These nuts exhibit good formability and weldability while offering a balance of strength, ductility, and corrosion performance—ideal for cost-effective yet durable fastening solutions in both industrial and automotive environments.
