803591178 Hexagonal Head Bolt XCMG XDE130 Electric driving dump truck spare parts

The 803591178 hexagonal head bolt effectively solves problems such as loose connections, misalignment, unstable structure, vibration-induced loosening, and fixation failure in equipment components. It is compatible with XCMG excavators, cranes, aerial work platforms, loaders, and other engineering machinery, widely used for locking and fixing machine bodies, sheet metal housings, electrical control brackets, and mechanical components. Relying on its standard hexagonal structure, it precisely locks components with tight and uniform thread engagement, resisting high-frequency vibrations during equipment operation and enhancing overall assembly stability. It is an indispensable standard fastener for engineering machinery assembly systems. Made of high-strength alloy material, it undergoes tempering hardening, precision thread rolling, and rust and corrosion prevention treatment. It has passed tensile and compressive strength, vibration resistance, durability, and weathering pressure tests, exhibiting high structural strength, strong locking force, and resistance to stripping and loosening.
