Loctite® Threadlocker Red 271™ is designed for the permanent locking and sealing of threaded fasteners. The product cures anaerobically, when there is an absence of air between close fitting metal surfaces. It protects threads from rust and corrosion and prevents loosening from shock and vibration. It is only removable once cured by heating up parts to 450°F (232°C).
