Screw Maintenance Methods

1. Regular Inspection

Monthly inspection of screw surface corrosion and deformation, with focus on load-bearing areas.

Retighten critical areas using a torque wrench (e.g., wheel bolts at 100-120 N·m).

2. Cleaning and Rust Prevention

Clean oil-stained screws with a neutral detergent. Thoroughly dry and apply rust-preventive oil.

Perform maintenance immediately after rust removal (neutralize residual chemicals after chemical rust removal).

3. Special Handling

Store removed bolts with positional markings (e.g., left front wheel/right rear wheel).

For long-term storage, vacuum-seal or nitrogen-flush bolts.

3. Special Handling Store disassembled screws by position (e.g., left front wheel/right rear wheel). For screws not in use for extended periods, vacuum packaging or nitrogen-filled storage is recommended.
