Stainless Steel Screws for Marine, Aerospace, and Industrial Fastening

Our stainless steel screws are engineered for high-performance fastening in demanding environments. Available in 304, 316, and duplex 32205 stainless steel, these screws offer excellent corrosion resistance and high tensile strength. With full size customization from M2 to M8 and lengths up to 100mm, they meet the exact requirements of aerospace, marine, petrochemical, and heavy machinery industries. Manufactured in compliance with ISO, DIN, ASTM, and other international standards, they provide reliable, long-lasting performance.

Key Selling Points

  • Corrosion resistance: Made from 304, 316, or duplex 32205 stainless steel, these screws withstand seawater, acid, and alkaline environments, reducing maintenance costs and extending equipment lifespan.
  • High mechanical strength: Available in strength grades A2-70 and A4-70, ensuring high tensile and anti-fatigue properties for critical applications.
  • Full size customization: Diameters from M2 to M8 and effective lengths from 6mm to 100mm, allowing precise fit for diverse assembly needs.
  • Global standard compliance: Manufactured to ISO, DIN, ASTM, ASME, ANSI, and JIS standards, simplifying international project approval.
  • Multiple surface treatments: Options include passivation, Dacromet, and adhesive pre-coating, enhancing corrosion protection and locking performance.
  • Rigorous quality control: Independent laboratory performs dimensional and mechanical tests, ensuring consistent quality and reliability.
