LOCTITE® 290 Wicking Grade Threadlocker

Features and Benefits

Available sizes:

Very thin (low viscose) threadlocker with the ability to flow into difficult to reach cracks and crevices, making it ideal for locking preassembled fasteners.
LOCTITE® 290 is a green, 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 (also referred to as wicking grade threadlocker). 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 seals porosities in welds, castings and powdered metal parts.
  • Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws
  • Seals porosities in welds, castings and powdered metal parts
  • Proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids
  • Requires heat for disassembly
