Permatex High Strength Red Threadlocker is a professional-grade anaerobic adhesive designed for the permanent locking and sealing of threaded fasteners. You will find that this high-viscosity liquid is specifically engineered for heavy-duty applications where assembly bolts must withstand intense vibration, shock, and extreme environmental conditions. The product feels incredibly secure once cured, effectively “welding” the nut and bolt together to prevent loosening while also sealing the threads against rust and corrosion. Because it is a “permanent” grade locker, this 6 mL tube is the ideal choice for critical automotive and industrial assemblies, such as frame bolts, cylinder block studs, and shock absorber mounts, where accidental loosening could lead to catastrophic equipment failure.

To achieve the most reliable bond, you should ensure the threads are completely free of oil, grease, and old adhesive by cleaning them with a dedicated parts cleaner or brake cleaner before application. You should apply a few drops of the red liquid directly onto the bolt at the nut engagement area. There is no need to coat the entire length of the bolt. Because this is a high-strength permanent locker, you should be aware that disassembly will likely require localized heating with a torch to approximately 500°F (260°C) to soften the adhesive before the bolt can be turned with hand tools. It is a good practice to avoid using this on plastic fasteners, as it is only intended for metal-to-metal contact where the absence of air triggers the curing process.
