800168993 HEXAGON SCREW [XCMG XE2000 Genuine Hex Screw | Part No. 800168993 | 12.9 Grade Ultra-High Strength | Seismic Resistance & Anti-Loosening | Expert in Heavy-Duty Equipment Structural Connections]

A single nail protects against immense power

The XCMG XE2000 excavator original hex bolts (part number 800168993) are the core fasteners for the boom, chassis and slewing mechanism of the equipment! Designed specifically for extreme heavy-duty working conditions, they use 12.9 grade ultra-high strength alloy steel and anti-loosening thread technology to resist severe vibration and impact loads, and eliminate major structural safety hazards caused by bolt breakage and loosening.

Why choose the original 800168993 hex screw?

✅ Grade 12.9 ultra-high strength alloy steel｜Tensile strength up to 1220MPa

It adopts cold heading and tempering heat treatment process, with a hardness of HRC39-44 and a fatigue life of 5 times that of ordinary 8.8 grade bolts!

✅ Triangular anti-loosening thread technology | Improves seismic performance by 70%

The unique thread angle design and surface phosphate treatment create a mechanical self-locking effect, maintaining zero preload decay even after 100,000 vibration tests!

✅ Zinc-nickel alloy coating | Increases corrosion resistance and service life by 3 times

Passing 1000 hours of salt spray testing, the surface zinc-nickel alloy plating + yellow passivation seal provides lifelong resistance to rain, oil, and gravel impact corrosion!

✅ Preventative Replacement | Avoiding the Risk of Structural Failure

A single original high-strength screw can prevent boom hinge loosening, chassis cracking, or abnormal rotation noise, saving 80% of maintenance costs and 90% of downtime losses!
