Permatex Red Threadlocker

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

The maximum strength “red” formula provides the most steadfast resistance to disassembly and is ideal for larger nut and bolt applications from 3/8″ to 1″ (10mm to 25mm). For smaller fasteners or less extreme conditions, use medium-duty Blue Threadlocker from Permatex.
