Agricultural machinery operates in harsh and complex outdoor environments, facing long-term exposure to wind, rain, high humidity, dust, mud, and extreme temperature changes. Field working conditions bring continuous mechanical impact, strong vibration, and heavy load friction to equipment fasteners. Fasteners must resist severe oxidation, rust, corrosion, and fatigue wear, while avoiding loosening, deformation, fracture, and failure under long-duration high-load operation. The core industry challenges focus on high toughness, strong anti-vibration performance, superior weather resistance, heavy-load bearing capacity, and durable anti-loosening performance required for long-cycle outdoor agricultural operations.
