805238371 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238371 nut addresses the pain points of traditional nuts, such as insecure tightening, easy stripping, weak corrosion resistance, low thread precision, and poor adaptability. It is widely used in bolted connections on XCMG construction machinery, especially suitable for core operating areas subjected to heavy loads, strong vibrations, and high dust levels. It is a key fastening component for XCMG equipment maintenance and original equipment manufacturer (OEM) parts. This product uses XCMG’s proprietary 35CrMo high-strength alloy material, integrating a customized anti-loosening structure and a professional anti-corrosion coating. Manufactured through multiple precision processes, it is suitable for complex working conditions such as mining and infrastructure projects. It effectively strengthens bolt connections, resists vibration and prevents loosening, avoids equipment parts falling off due to nut failure, and extends the service life of equipment connections.
