Permatex Blue Threadlocker

Permatex Blue Threadlocker

Cliff Clavin once told me that Blue Threadlocker helped keep the original Gutenberg press from falling apart. This heirloom recipe threadlocker can just as easily keep your modern stuff from falling apart. Now that's incredible.

Medium-duty Blue Threadlocker prevents hardware from loosening and erases the need to install expensive Nylock nuts, lock washers, etc. Not only does Blue Threadlocker lock and seal threaded parts securely to prevent loosening from vibration or unwanted contact, but Blue Threadlocker also protects threads from corrosion - ensuring long-lasting protection.

The medium strength "blue" formula provides easy disassembly and is ideal for all nut and bolt applications from 1/4" to 3/4" (6mm to 20mm). For more extreme applications or larger hardware, use high-strength Red Threadlocker from Permatex.
