【Lock Tight Thread Lock】Thread lock can prevent nuts, bolts, bearings, fasteners and screws due to long-term vibration and loosening, rust and corrosion, so as to fix locking and sealing of metal nuts and screws. The unique anaerobic function makes the interface perfectly isolated from the outside air and corrosive liquid. Even in extreme environments such as high temperature, high humidity, high vibration, etc., thread locker to have excellent characteristics to prevent leakage, rust and corrosion.

【Red and Blue Thread Lock Set】We offer 50ml medium strength blue thread lock and 50ml high strength red thread lock to ensure that most of the working conditions that customers need. It has excellent locking sealing capability and stable and long-lasting anti-floating effect, ensuring bolts, nuts and metal fasteners are tightly secured in place.

【Thoughtful Bottle Design】This locktight threadlocker uses an anaerobic curing process—meaning it hardens only in the absence of air. That’s why the bottle isn't filled to the top; nearly half of the space is intentionally left empty to prevent premature curing. Though it may appear half full, the threadlocker contains a full 50ML of high-performance adhesive.

【Easy to Use】Clean and dry the surface of the parts before use, then apply a thread locking agent to the threads, tighten the nut to the locking agent position in 3 minutes, no further adjustments after curing, and fully cure within 24 hours after initial curing for 20 minutes. Very easy to use, the medium-strength thread-locking agent can be disassembled with manual tools.

【Widely Used】Whether you're tightening parts on a car, motorcycle, bicycle, or working on home appliances, furniture, electronics, or industrial equipment. This thread locker is your go-to solution. Ideal for DIY enthusiasts and professionals in the repair industry, the thread lock formula ensures metal screws stay secure and safe.
