Reliable locking for preassembled fasteners

Practical benefits

Penetrating post assembly application: Low viscosity allows the formula to wick between engaged threads via capillary action without requiring prior disassembly.
Loctite resists heavy vibration: You prevent fastener loosening and fluid leakage caused by intense shocks and repeated industrial vibrations.
Seals porosity in metal: You can easily seal small porosities in welds, castings, and powdered metal components.

In a nutshell

The right choise for

With Loctite 290, you securely lock and seal metal threaded connections without needing prior disassembly. Thanks to its low viscosity, this liquid formula wicks effortlessly between already engaged threads, set screws, and bolts via capillary action. This prevents fasteners from vibrating loose or developing leaks under heavy shocks and continuous vibration. In addition, it reliably seals microporosities in welds and metal castings. It adheres effectively to metals such as steel, stainless steel, and brass, and remains serviceable using standard hand tools. This 50 ml bottle provides a fast and practical solution for maintenance and overhaul tasks.
