In a nutshell
The right choise for
With Loctite 270 threadlocker, you permanently secure and seal heavy-duty threaded assemblies against severe shock, heavy vibration, and thermal expansion. Suitable for bolts, nuts, and studs up to M20, it cures effectively on all active and passive metals, including stainless steel and aluminium, without requiring a primer. It also tolerates minor oil residues on fasteners, saving you valuable preparation time. Once cured, it reliably seals threads against leaks and corrosion across an operating temperature range of -55 °C to +180 °C. When maintenance is required, the assembly can be disassembled using standard hand tools after applying localized heat to 250 °C or 300 °C.
