Secure locking with Loctite 245

Practical benefits

Suited for large fasteners: You reliably lock and seal large threaded connections up to M80 in size.
Disassembly with hand tools: With its medium strength, you easily disassemble treated fasteners using standard hand tools.
Controlled and precise application: The high viscosity formula stays in place on the thread without running off.

In a nutshell

The right choise for

With Loctite 245, you reliably lock and seal large threaded assemblies up to M80. This liquid threadlocker prevents heavy bolts, nuts, and studs from loosening under continuous vibration and shock loads in machinery and heavy equipment. Thanks to its high viscosity, the compound stays exactly where applied without running off or dripping through larger thread gaps. It also protects assemblies by sealing threads against moisture, corrosion, and fluid leaks. When periodic servicing is required, the medium-strength formula allows you to disassemble treated fasteners made of steel, brass, or stainless steel easily using standard hand tools. This 50 ml tube delivers clean, controlled application for demanding assembly tasks.
