Permatex Blue Threadlocker

Permatex's Medium-duty Blue Threadlocker offers a reliable solution to prevent hardware from loosening without the need for costly Nylock nuts or lock washers. This versatile adhesive not only securely locks and seals threaded parts, safeguarding against vibration-induced loosening or unintended movement but also shields threads from corrosion, ensuring long-lasting protection. Its medium strength, known as the "blue" formula, allows for easy disassembly and is suitable for various nut and bolt applications ranging from 1/4" to 3/4" (6mm to 20mm) in size. For more demanding scenarios or larger hardware, Permatex's high-strength Red Threadlocker is recommended.
