805238378 Nut XCMG XDE130 Electric driving dump truck spare parts

The 805238378 nut is a high-strength fastener compatible with XCMG’s original equipment manufacturer (OEM). Specifically designed for XCMG excavators, cranes, and other construction machinery, it addresses the pain points of ordinary nuts such as thread stripping, loosening, fatigue fracture, and poor corrosion resistance. Widely used in critical components such as equipment frames, booms, hydraulic lines, and supports, it is a core component for equipment maintenance. This product conforms to XCMG’s matching standards and the national standard GB/T 3098.2. It is made of 35CrMoA high-strength alloy steel, undergoing 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 high-strength bolts of the same grade, ensuring even stress distribution and effectively extending the service life of equipment and fasteners.
