800169006 bolt XCMG XE2000 excavator spare parts

XCMG XE2000 Dedicated High-Strength Bolts | Original Part Number 800169006 | Heavy-Duty Fastening, Anti-Loosening and Vibration Resistant | Safeguarding Every Connection

In the structure of an excavator weighing hundreds of tons, the strength of every bolt is crucial to overall safety! XCMG XE2000 excavator original high-strength bolts (part number 800169006), made of 12.9 grade ultra-high strength material and using a special anti-loosening process, provide absolutely reliable fastening for critical connections, preventing loosening and safeguarding safety!

Core advantage: The irreplaceable nature of the original factory bolts (800169006)

1.12.9 grade ultra-high strength

Made of 35CrMo special alloy steel, and heat-treated by quenching and tempering, it has a tensile strength of 1220MPa and a yield strength of 1100MPa, far exceeding that of ordinary 8.8 grade bolts, completely eliminating the risk of breakage.

2. Patented anti-loosening design

The threaded parts are coated with a nano-level damping coating, and the coefficient of friction is kept stable in the range of 0.12-0.14 to ensure the rated preload and maintain the locking force without decay under continuous vibration.

3. Superior corrosion resistance and protection

The Dacromet coating (zinc-chromium coating) provides corrosion protection and withstands over 1000 hours of salt spray testing, making it suitable for humid, acidic, and alkaline environments in mines, extending its service life by 3 times.

4. Precise torque matching

The torque coefficient K value is kept stable at 0.18-0.22 to ensure that each group of bolts is subjected to uniform force and to avoid connection failure due to torque deviation.

Key application parts

• Core structural connections: track frame to platform connection, boom base, bucket articulation point
• Powertrain mounting: Engine mount, hydraulic pump flange, gearbox connection
• Slewing bearing installation: Slewing gear ring fixing bolts, slewing motor connection
