Maximum security of critical connections

Liqui Moly Threadlocker Heavy Duty is a high strength threadlocker designed for permanent or semi-permanent connections where maximum security is required. The product provides extreme resistance to vibration and ensures that critical bolts and screws remain tightened under the harshest conditions.

Advantages of Screw Lock Heavy Duty

• High strength: Maximum security of critical connections
• Extremely vibration-proof: Prevents loosening even under extreme loads
• Temperature resistant: Works optimally from -55°C to +150°C
• Permanent locking: Ideal for connections that rarely need to be disassembled
• Requires heat for disassembly: Loosens by heating to approx. 250°C
• Protects against corrosion: Completely seals threads against moisture and rust

Areas of application on motorcycles

Perfect for critical and permanent connections such as:

• Engine block and crankcase bolts
• Cylinder head and cylinder head bolts
• Gearbox and clutch housing fastening
• Swingarm pivot bolts
• Frame and structural connections
• Crankshaft and flywheel bolts

Application and use

Clean threads thoroughly to remove oil, grease and dirt. Apply threadlocker evenly to threads and assemble connection immediately. The product cures anaerobically (without oxygen) between metal surfaces and reaches full strength after 24 hours. When disassembling, heat the connection to approx. 250°C with a heat gun or flame.

Warning: High strength - requires heat when disassembling. Not suitable for connections that need to be loosened regularly.
