Permanent locking with Loctite 278

Practical benefits

Resists severe vibration loosening: You keep heavily loaded threaded assemblies securely in place against continuous shocks and mechanical stress.
Withstands high operating temperatures: You safely apply this adhesive in demanding thermal environments thanks to heat resistance up to 200 °C.
Seals against leaks and corrosion: You protect metal threads from moisture intrusion while preventing fluid leakage across critical joints.

In a nutshell

The right choise for

With Loctite 278, you permanently lock and reliably seal heavily loaded threaded assemblies. This green, medium-viscosity threadlocker prevents bolts, nuts, and studs from loosening under extreme vibrations and continuous shocks in machine building and vehicle engineering. Thanks to its heat resistance up to 200 °C, your connections maintain maximum strength even in demanding thermal operating conditions. Suitable for both active and passive metals, this liquid threadlocker fully seals metal threads against fluid leaks and corrosion, giving you total confidence in your most critical fastener joints.
