Product Overview This product is a high-quality stainless steel threaded stud / double-end stud bolt, available in SS304, SS316, and SS201 material grades. It is designed for reliable fastening in demanding industrial, construction, and marine environments, offering excellent corrosion resistance, high tensile strength, and long-term durability. The studs are available in M16 and a wide range of metric sizes, with options for full-thread or double-end configurations. Material Grades & Properties Grade Standard Equivalent Key Characteristics SS304 A2 (ISO 3506) General-purpose corrosion resistance; suitable for most industrial and outdoor applications SS316 A4 (ISO 3506) Superior corrosion resistance, especially against chlorides and marine environments; ideal for chemical, coastal, and high-humidity applications SS201 — Cost-effective alternative with moderate corrosion resistance; suitable for indoor and light-duty applications Stainless steel fasteners are classified under BS EN ISO 3506, where A2 corresponds to 304-grade and A4 corresponds to 316-grade austenitic stainless steels. Mechanical property classes such as A2-70 and A4-80 indicate minimum tensile strengths of 700 MPa and 800 MPa respectively. Specifications Parameter Details Product Type Threaded Stud / Double-End Stud Bolt / Full-Thread Rod Material Stainless Steel 304 / 316 / 201 Thread Size M16 (also available: M3–M52) Standard DIN 938 / DIN 939 / DIN 975 / DIN 976 / ISO / ANSI / ASTM / GB Thread Type Metric coarse or fine thread Length Range 20 mm – 3000 mm (customizable) Surface Finish Plain / Passivated Tensile Strength 500–720 MPa (304 grade); ≥515 MPa for 316 Hardness 240–310 HB DIN 938 double-end studs feature a thick shank design with b₁ = 1d (thread length on the screw-in end equals one nominal diameter), ensuring secure engagement in tapped holes. The thread pitch for M16 coarse thread is 2.0 mm, and for fine thread it is 1.5 mm. Mechanical Properties (Reference) For SS304 stud bolts at M16 size: Tensile Strength: 500–720 MPa Surface Hardness: 240–310 HB Rust Proof: Yes (passivated surface treatment) For SS316, the minimum tensile strength is typically ≥515 MPa with ≥205 MPa 0.2% proof stress and ≥40% elongation. Applications Stainless steel threaded studs and double-end bolts are widely used in: Flange connections in piping systems (oil, gas, chemical) Structural steel fastening in construction Marine and offshore environments (SS316 recommended) Automotive and heavy machinery assembly Chemical processing equipment Power plants and industrial installations Packaging & Customization Export Packing: Wooden box / crate Domestic Packing: Standard corrugated / cardboard box OEM/ODM: Available — custom sizes, thread types, materials, and surface finishes can be produced according to drawings or samples MOQ: Negotiable Quality Assurance All products are manufactured under strict quality control procedures in accordance with international standards (DIN, ISO, ANSI/ASTM, GB, JIS, BSW).
