805238371 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238371 nut is a high-strength fastener compatible with XCMG’s original equipment manufacturer (OEM) and specifically designed for XCMG excavators, cranes, and other construction machinery. It addresses common issues such as thread stripping, loosening, fatigue fracture, and poor corrosion resistance. Widely used in equipment frames, booms, hydraulic lines, and supports, it is a key component for equipment maintenance and repair. This product adheres to XCMG’s matching standards and GB national standards, using 35CrMoA high-strength alloy steel. It undergoes heat treatment (quenching + high-temperature tempering), precision thread rolling, and Dacromet surface anti-corrosion treatment. Suitable for the complex working conditions of construction machinery, including high temperature, high dust, high-frequency vibration, and oil corrosion, it is perfectly compatible with bolts of the same material, ensuring even stress distribution and extending the service life of equipment and fasteners.
