Thread Lock Loctite 290

Thread locking medium, medium high/high strength. Ideal for locking preassembled fasteners.

LOCTITE 290 is a liquid medium/high-strength threadlocker designed for the locking and sealing of threaded fasteners. Because of its low viscosity and capillary action, the product wicks between engaged threads and eliminates the need for disassembly prior to application. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The product can also fill porosity in welds, castings and powdered metal parts.

The advantages:
Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws.
Only works on metal.
Proven to be tolerant of minor contamination due to industrial oils, e.g. engine oils, corrosion prevention oils and cutting fluids
Requires heat for disassembly.
