From Loctite: When it comes to bonding locating pins in radiator assemblies, sleeves in pump housings and bearings in auto transmissions – especially when you need high temperature resistance up to 232°C (450°F) – LOCTITE® 620 is a good choice. This high-strength, anaerobic-curing retaining compound is designed for bonding cylindrical fitting parts to prevent loosening and leakage due to shock and vibration. It cures when confined in the absence of air between close-fitting metal surfaces, and can fill gaps from 0.15 mm - 0.25 mm (0.006" - 0.01").
