XCMG XE2000 Special Screw 805139981 (M8×70) – The Structural Guardian of Heavy-Duty Equipment

When thousand-ton excavators face extreme working conditions, the reliability of every connecting component is directly related to the structural safety of the entire machine. The original factory bolts (part number: 805139981, specification M8×70), specially developed for the XCMG XE2000 ultra-large hydraulic excavator, with their superior mechanical properties and precise fit, have become indispensable “structural guardians” for critical connection parts of the equipment, providing solid protection for heavy-duty operations.

This product is manufactured using 12.9 grade high-strength alloy steel through precision cold heading technology. The threads are formed using roll forming technology, and the surface undergoes phosphate rust prevention treatment, resulting in extremely high tensile strength and fatigue resistance. Strictly adhering to XCMG’s original technical standards, the thread precision reaches 6g level, ensuring a perfect fit with equipment connection points. The unique shank strength design allows the screw to maintain stable preload even under severe vibration conditions, effectively preventing loosening and falling off.

Suitable for critical connection parts such as cover plates, brackets, and housings of XE2000 excavators, this screw can withstand a temperature range of -30℃ to 150℃, has excellent corrosion resistance, and maintains a long service life even in harsh working conditions. Its durability, tested for 100,000 vibration cycles, ensures a reliable connection throughout the entire lifespan of the equipment.

Choosing the original part number 805139981 screw not only ensures the structural safety of the equipment but also prioritizes its stable operation. Let precision fasteners protect against thousands of tons of force, and let reliable connections define professional value!

Note: This product is suitable for XCMG XE2000 series excavators. Please confirm the equipment model and part number match your requirements before purchasing.
