3465463 partial thread bolt is a special high-strength fastener for transmission, drive axle, differential and flange assembly of construction machinery. It adopts a partial thread design, the unthreaded shank is used for precise positioning, guiding and clearance control, while the threaded section provides reliable locking force. Made of high-strength alloy steel with quenching and tempering treatment, it has high tensile strength and strong shear resistance. It is suitable for key connecting parts requiring high positioning accuracy and locking reliability, and can remain stable and loose-proof under heavy load, vibration and impact conditions for a long time.

Application Scenarios
Suitable for key parts such as transmission housing, differential housing, flange assembly, bearing seat and main reducer of loaders, graders, rollers, forklifts and other construction machinery. Used for connecting structures that need both positioning and fastening to ensure component coaxiality and assembly accuracy, adapting to continuous vibration, alternating loads and heavy-duty working environments.
Common Faults & Troubleshooting
- Thread stripping: Caused by excessive installation torque or material fatigue. Replace 3465463 bolt and tighten to standard torque.
- Fracture damage: Due to impact overload or uneven preload. Replace with new bolt and check assembly surface flatness.
- Loosening and falling off: Caused by vibration fatigue or locking failure. Replace bolt and use with lock washer or thread locker.
- Shank wear: Positioning accuracy reduced due to long-term micro friction. Replace bolt directly to ensure assembly positioning.
