805046525 Bolt XCMG XDE130 Electric driving dump truck spare parts

The 805046525 bolt is a high-strength bolt 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 bolts such as thread stripping, insufficient tensile strength, 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 3098.1. 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 nuts of the same grade, ensuring even stress distribution and effectively extending the service life of equipment and fasteners.
