- Rustproof, Waterproof & Heat Resistant: Nanoxa thread locker creates a tight, durable seal that resists water, rust, corrosion, and leaks—even in tough conditions. The anaerobic formula fills thread gaps and locks fasteners securely. Perfect for both indoor and outdoor use, our thread lock ensures long-lasting performance and reliable protection
- Locks Tight & Lasting Hold: Nanoxa thread lock delivers superior adhesion and anti-loosening performance. Even under heavy vibration or shock, it keeps screws, nuts, and fasteners securely in place—ensuring lasting stability and safety. This value 2-pack includes medium-strength blue (removable) and high-strength red (permanent) thread locker—meets all fastening needs
- Easy Application: Equipped with a precision tip featuring a pull-up opening and press-down seal, it keeps the glue fresh and enables accurate application. Simply apply evenly to bolts and nuts, then tighten, and allow 20 minutes for initial cure and 24 hours for full strength. The medium-strength blue threadlocker can be removed with basic hand tools, while the high-strength red version requires heat for disassembly
