LOCTITE 29021 Threadlock Adhesive

The LOCTITE 290 adhesive comes in a 10ml bottle and is designed for locking and sealing threaded fasteners. Its low viscosity enables capillary action, allowing it to wick between engaged threads without disassembly. It cures anaerobically in confined spaces between close-fitting metal surfaces, preventing loosening and leakage from shock and vibration. It effectively fills porosity in welds, castings, and powdered metals. The green liquid adhesive is easy to apply, resistant to many solvents, and removable with heat or mechanical tools. Its features include low toxicity, non-flammability, and suitability for preassembled bolts up to 1/2 inch diameter.
