Applicable Scenarios

Suitable for maintenance and overhaul of feeder guards, sprocket retaining plates, pipe supports, auxiliary brackets and covers on XCMG RP705 crawler paver; replacement of failed original bolts; standard fasteners for asphalt paving machinery; M12 high‑strength bolts stocked by construction parts suppliers.

▪ OEM standard dimension: Accurate M12×40 size with stable thread tolerance and excellent interchangeability.
▪ Tempered reinforced substrate: Outstanding tensile and fatigue resistance for continuously vibrating light‑to‑medium load positions.
▪ Rolled thread: Continuous metal grain delivers good wear resistance and reliable engagement after repeated disassembly.
▪ Anti‑corrosion surface treatment: Reduces rust from mud and asphalt dust and lowers the risk of thread seizure.
▪ Standard hex head: Compatible with common sockets for convenient service in tight spaces.
▪ Good compatibility: Works with matching flat and spring washers for locking on vibrating joints.

FAQ

Q: Can bolt 805048018, M12×40, be used on other construction machines?
A: It may be substituted if grip length, strength grade and load conditions match. It is primarily an OEM replacement for the XCMG RP705.

Q: Can a bolt with light surface rust but intact threads stay in service?
A: It may be used temporarily after cleaning if free of thread damage, stretching and cracks. Replace it if threads are scored or the shank is elongated.

Q: What should be noted when installing this high‑strength bolt?
A: Clean asphalt and debris from threads before fitting, tighten covers and retaining plates diagonally in stages to specified torque, and use lock washers or thread locker for vibrating joints.

Q: What commonly causes bolt failure?
A: Over‑torqueing, repeated impact from insufficient preload, corrosion by leaked oil and thread damage during disassembly.

Q: Can high‑strength bolts be reused after removal?
A: Repeated reuse is not recommended after heavy preload and impact. Replace at once if deformation, corrosion or thread damage is found.
