Types of Thread lockers & Their Usage:
A thread locker is an anaerobic adhesive applied to threaded fasteners such as bolts, nuts, and screws. It prevents loosening caused by vibration and enhances the reliability of assemblies.
🔵 1. Low Strength
Ideal for small screws and adjusting fasteners. Can be easily removed with standard hand tools when needed.
🟣 2. Medium Strength
One of the most common grades for general-purpose applications. Offers a good balance between vibration resistance and future disassembly.
🔴 3. High Strength
Designed for permanent or difficult-to-remove fastening. Used in high-vibration and heavy-duty assemblies.
🟠 4. High-Temperature Grade
Developed for assemblies where fasteners are exposed to elevated temperatures.
🟢 5. Wicking Grade
Due to its low-viscosity formulation, it can pe*****te into already-assembled fasteners via capillary action.
🟡 6. Removable Strength
For threaded joints that require vibration resistance but also need to be disassembled for future maintenance.
🔵 7. Pipe Thread Sealant
Used for sealing and reducing leakage in pipe threads.
8️⃣ Penetrating Grade
An extremely low-viscosity material designed to pe*****te into assembled threads.
⚫ 9. Vibration-Resistant Grade
Useful for keeping threaded connections secure under high-vibration and shock conditions.
⚙️ Key Factors to Consider When Choosing a Threadlocker
✔ Required strength
✔ Operating temperature
✔ Fastener size
✔ Future disassembly requirements
✔ Vibration and shock levels
✔ Oil/contamination conditions
✔ Thread material
✔ Application and curing requirements
Engineering Tip: Do not determine threadlocker strength by color alone. Always verify the specific product grade using the technical data sheet and manufacturer recommendations, as color/grade conventions may vary across product families.
