Review: Excellent blue/removable thread locker! - Fantastic product that holds tight but is removed with reasonable torque. Bottle and needle is done well and doesn't leak or make a mess. Dries quick and sets to full strength in 24 hours, color is just like the brand new stuff that's far more expensive. The thickness/viscosity of the fluid is the same as the name brand product. Overall this is a quality product at a great value and performs exactly like the name brand product. You get a half a life time supply for very little money.
Review: Great hold. Easy to use. Not expensive at all - It works really well. It’s held for 4 months so far and still holding. I’ve used it on multiple occasions and not had any issues yet. Great value for the cost.

## Features

- Prevents Rust and Corrosion: Protects from leaks, rusting, and corrosion and eliminates need to stock up on expensive lock nuts and washers
- Easy to Use: Simply apply the threadlocker evenly to the thread, tighten the nut, and cure initially for 20 minutes, then your Items can be used normally after fully cured in 24 hours
- Wide application : Whether you're installing a valve cover, water pump, or just tightening down some furniture screws, our adhesive solution can be used in various automotive, industrial, and furniture applications.
- Why The Bottle Is Not Full: Threadlocker will solidify in anaerobic conditions, so the bottle is half-full to ensure the threadlocker remains liquid, prevent solidification and hardening.
