When replacing screws, it's good practice to inspect these related components, as they often wear out or become damaged at the same time.
Flat or lock washers used with these screws may be crushed or worn. Replace them to maintain proper clamping force.
If threads in the mating component are damaged, a thread repair insert or replacement nut may be needed.
Inspect plastic or metal covers for cracks around mounting holes that may have contributed to screw loosening.
