Permanent locking and vibration resistance define Loctite 270, Thread Locking Adhesive, Maximum Strength, 50 ml, engineered to secure threaded fasteners and prevent loosening under heavy load or thermal stress. Its anaerobic formulation cures between metal surfaces to create a high-strength bond that resists shock, corrosion, and leakage. Designed for permanent assemblies, it allows disassembly only with localized heat or special tools when service is required. The green formula provides easy visual identification during application. Ideal for marine engines, heavy machinery, and metric fabrication, Loctite 270 delivers unmatched retention, durability, and long-term fastening security.
