What Causes Engine Screws to Rust?

[StDonovan]

Engine screws rusting is a very normal occurrence, unless they are titanium screws, but engines definitely do not use titanium screws. If steel or copper screws are used, they will also rust, especially in humid environments where rusting occurs even faster. Rust Prevention Measures: Vehicle screws are actually treated with rust prevention methods when they leave the factory. After exposure to oxidation in most environments, some mild rusting occurs. If the rusting is severe, the screws can be replaced. If the rusting is not too severe, it will not affect the driving safety of the car. There are specialized rust removers that can easily clean off the rust stains. Maintenance Tips: Regular maintenance and timely cleaning of the car engine are essential. Cleaning off dust and surface water accumulation can effectively prevent screws from rusting and aging. The engine environment is particularly harsh and must endure cold or humid weather, with many components being exposed. Regular maintenance can also effectively address these issues.
