Description
LOCTITE 277 – HIGH-STRENGTH THREADLOCKER | 50ML | ANAEROBIC ADHESIVE
Overview:
Loctite 277 is the strongest red threadlocker in the Loctite range, specially designed for permanently securing large threaded connections (up to M80) that operate under heavy loads and harsh conditions.
Thanks to its high viscosity and thixotropic properties, it stays in place on threads and perfectly fills gaps between surfaces. Once cured, it creates a bond that is practically unremovable without special tools or heating.
Key Features:
-
Extremely high mechanical strength: Break torque for M10: 32 Nm
-
High viscosity and thick consistency: Ideal for large threads and vertical applications
-
Resistant to light oil contamination: Does not require perfectly degreased surfaces
-
Prevents loosening and corrosion: Effective even in high-vibration environments
-
UV fluorescence: Enables easy inspection of correct application
-
Disassembly only possible with heat: Up to approximately 250°C
-
Solvent-free: Safe for most metals
Applications:
-
Heavy industrial machinery
-
Agricultural and construction equipment
-
Threaded connections in gearboxes, engines, and turbines
-
Securing bolts and nuts against self-loosening
-
Connections exposed to vibrations and variable loads
