Thread Locker
Thread locker is an adhesive applied to bolt threads to prevent loosening from vibration.
What is Thread Locker?
Strengths vary from removable to permanent. It cures without air between metal surfaces. Some new bolts come pre-coated. Colours usually indicate strength: blue for medium strength that can be removed with hand tools and red for high strength. Surfaces must be clean and oil-free for good results. Some manufacturers specify pre-coated bolts that must be replaced rather than reused.
How it works
The liquid hardens in the threads and locks them.
Why it matters for your car
Use only where specified. High-strength types may need heat to remove.
