Stainless steel screws and nuts serve as fundamental fastening components, achieving the reliable securement of parts through threaded engagement to ensure structural stability. Their core functions include: withstanding dynamic loads (such as mechanical vibration), enhancing structural strength (with a tensile strength exceeding 400 MPa in structural steel applications), and exhibiting corrosion resistance (withstanding salt spray tests for ≥96 hours) as well as electrical conductivity (with a resistivity of 1.0 × 10⁻⁶ Ω·m).
Enabling Mechanical Connection: By engaging internal and external threads, components are securely fastened together, forming a detachable assembly.
Providing Anti-loosening Functionality: Certain stainless steel nuts feature a self-locking design that effectively resists loosening caused by vibration, making them suitable for high-vibration environments such as mining machinery, automotive systems, and aerospace applications.
Corrosion Resistance: In harsh environments-including those involving moisture, acids, alkalis, or salt spray-stainless steel nuts rely on a surface passivation film to resist oxidation and chemical erosion, thereby extending their service life.
