| LOCTITE® 620 is a high-strength, anaerobic-curing retaining compound designed for bonding cylindrical fitting parts. Ideal for applications requiring high temperature resistance (up to 232°C), it prevents loosening and leakage due to shock and vibration. It cures in the absence of air between close-fitting metal surfaces and fills gaps from 0.15 mm to 0.25 mm. Suitable for uses like locating pins, sleeves, and bearings in demanding assemblies. |
 |
- Ideal for shafts, gears, pulleys and similar cylindrical parts
- Operating temperature: -55°C to 230°C (-65°F to 450°F)
