Hazlewood Fasteners, based in Canberra, Australia, stands out as a leading manufacturer and supplier of top-notch Stainless Steel 304L Bolts. These bolts are crafted for outstanding corrosion resistance, strength, and durability. Made from low-carbon austenitic stainless steel, they’re designed to perform exceptionally well in tough and corrosive settings, especially where welding is involved. The SS 304L grade helps prevent carbide precipitation during welding, ensuring they remain durable and structurally sound. Built to meet international standards with precise dimensions and a smooth surface finish, SS 304L Bolts find their place in industries like chemical, marine, food processing, construction, and power generation.
Stainless Steel 304L Bolts consist of 18–20% chromium, 8–12% nickel, and a maximum carbon content of 0.03%, which gives them remarkable resistance to intergranular corrosion and oxidation. Their low-carbon makeup enhances weldability and stops carbide precipitation when exposed to heat. These bolts boast a tensile strength of 485–620 MPa, yield strength of 170–240 MPa, and an elongation of over 40%, ensuring they maintain good toughness in both high and low temperatures. With their excellent ductility, strength, and corrosion resistance, they’re perfect for long-term use in chemically aggressive and humid environments.

Stainless Steel 304L Bolts are commonly found in chemical processing units, pressure vessels, refineries, pipelines, marine structures, and food processing facilities, where rust and corrosion resistance is crucial. Their low carbon content makes them perfect for welded assemblies and situations where they’re exposed to moisture and acids. They’re also a great fit for the pharmaceutical, construction, and water treatment sectors, providing excellent structural integrity and hygiene. Offering reliable fastening solutions, SS 304L Bolts ensure secure joints and maintenance-free performance, even under varying temperatures and pressures.
Our commitment to quality is demonstrated by the rigorous testing procedures we apply to all our Stainless Steel 304H bolts before delivery. Some advanced tests include hardness, chemical analysis by Spectro analysis, positive material identification (PMI), levelling, micro-macro, pitting resistance, flare, and intergranular corrosion (IGC) tests. Among these high standards, we also issue commercial invoices and packaging lists; we provide necessary documents such as certificates of origin and documents proving the legality of the Trade Group or Embassy. To further ensure customer satisfaction, we offer third-party inspection certificates, proving our 304H bolts are quality and reliable for various applications.
