805046457 Bolt XCMG XDE130 Electric driving dump truck spare parts

The 805046457 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 complies with XCMG’s matching standards and GB/T 3098.1-2010 standards. It is made of 35CrMoA high-strength alloy steel, undergoing heat treatment, precision thread rolling, and Dacromet surface anti-corrosion treatment. Suitable for the complex working conditions of construction machinery, it perfectly matches high-strength nuts of the same grade, ensuring even stress distribution and effectively extending the service life of equipment and fasteners, thus meeting XCMG’s requirements for intelligent supply chain adaptation.
