29000 is a Permatex Penetrating Grade Threadlocker in green, supplied in a 6 ml tube. It is a low viscosity liquid that wicks along the threads of fasteners that are already assembled, so you lock them after the parts are together instead of before. Once cured it helps keep fasteners from backing out under vibration and shields the threads from corrosion. It suits fasteners from #2 to 1/2 in. (2.2 to 12 mm). To take the joint apart later, apply localized heat first and then use hand tools. The spec reference is ASTM D5363 AN0261 (Mil-S-46163A, Type III, Grade R). Sold by Pro Gear and Transmission.
