About this product

Medium Strength Threadlocker BLUE Gel - 35g

Permatex’s medium-strength Threadlocker Blue is ideal for all nut and bolt applications 1/4″ to 3/4″ (6mm to 20mm). Threadlocker Blue eliminates the need for stocking expensive lock nuts and lock washers and locks and seals while preventing parts from loosening due to vibration. Protects threads from corrosion. Threadlocker BLUE is easily removable with hand tools for easy disassembly. The Gel formula provides “liquid reliability” without drips, globs, mess, or waste and is available in convenient dispensing systems: choose the GEL TWIST® pin-point applicator or the GEL SQUEEZE® applicator. (Mil-S-46163A, Type II, Grade N).
