Loctite 620

LOC008

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)
