Surface Insensitive Threadlocker Blue (10 ml).

Permatex Surface Insensitive Threadlocker Blue is designed for fasteners from 1/4″ to 3/4″ (6mm to 20mm) and is particularly useful when dealing with fasteners that have a slight oil film. This oil-resistant formula effectively prevents loosening due to vibration and allows for easy disassembly with hand tools.
