805238397 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238397 nut addresses the pain points of traditional nuts, such as stripped threads, high-temperature softening, poor vibration resistance, easy loosening, and weak corrosion resistance. It is widely used in bolted connections on XCMG construction machinery, especially suitable for heavy-duty, medium-temperature, and high-vibration core components, making it a key fastener for equipment maintenance and installation. This product adheres to XCMG’s original factory standards, using 35CrMoA high-strength alloy material, and undergoes tempering heat treatment and anti-corrosion treatment. Suitable for complex working conditions such as mining, it achieves high-strength engagement, preventing loosening and failure, and extending the life of the fastening system. In terms of performance, it has a strength grade close to grade 12, a hardness of HV250-300, and a thread precision of ISO 4H. It uses Dacromet corrosion protection, shows no white rust after 48 hours of salt spray testing, and is suitable for environments from -30℃ to 400℃. It is creep-resistant, fatigue-resistant, and provides a tight fit, making it suitable for high-strength bolt applications in various XCMG equipment series.
