As a widely used auxiliary material, the unique properties of threadlocker make it a preferred choice in many engineering projects.
Today, we will dive into the various characteristics and applications of thread glue to help you gain insight into this important industrial adhesive so that you can make a more informed decision when choosing.
What is threadlocker， And How Does It Work？
Threadlocker is also called thread locking fluid, screw locking glue, and thread sealant. It is an anaerobic adhesive specially used for thread sealing and anti-loosening of metal fasteners. It is liquid when unopened. When applied to the thread surface when in use, it can penetrate deeply into the thread gap. After tightening the nut, let it stand for some time. It reacts with oxygen and solidifies to form a solid sealing layer, effectively preventing loosening caused by vibration. It also has waterproof and anti-corrosion effects.
Different Types Of Threadlocker
There are various types of threadlockers on the market, which can be roughly divided into the following categories according to their strength:
- Low-strength thread glue:
- This type of threadlocker is usually purple, such as Tanyo-222. Due to its low strength, it is easier to disassemble and is suitable for small bolts and nuts below M6.
- Medium-strength thread glue:
- Blue liquid thread lock glue, such as Tanyo-243, has medium locking strength and is moderately difficult to disassemble. It is suitable for medium fasteners below M20.
- Medium and high-strength thread glue:
- Green liquid medium and high-strength grade anaerobic glue, such as Tanyo-290. This thread glue has strong permeability and can be used after bolts and nuts are installed. It is suitable for fasteners not exceeding M25.
- High-strength thread glue:
- High-strength thread locker glue with red liquid, such as Tanyo-263, 271, 277, is not easy to remove, suitable for one-time sealing no more than M25, and maintenance-free accessories in the later stage.
- General thread glue:
- Thread locker of general strength grade, often blue liquid, can be disassembled with ordinary tools, suitable for fasteners between M6 and M25, such as our Tanyo-270.
- High-temperature thread glue:
- This type of thread locker is not only strong but also resistant to high temperatures. It can withstand temperatures of up to 230 degrees Celsius without losing viscosity, such as Tanyo-2701.
In short, thread lock glue’s colors are mainly divided into purple, blue, and red: purple represents low strength, blue represents medium strength, and red represents high strength and high temperature thread glue.
What does threadlocker do?
Threadlocker has a wide range of uses, and specific application areas include:
- Automobile manufacturing:
In the automotive industry, threadlocker is widely used in the assembly process of auto parts, especially in key parts such as the engine, chassis and transmission system. It can effectively prevent the bolts of the vehicle from loosening in a continuous vibration environment, thus significantly improving the safety and stability of the car.
- Aerospace field:
For the extremely demanding aerospace field, thread glue is also indispensable. It is used to connect aerospace engines and other sensitive electronic equipment, ensuring that these components can maintain normal working conditions even under extremely high-temperature conditions.
- Industrial machinery:
Threadlocker is also used during the assembly process of industrial machinery and equipment to avoid component loosening and corrosion problems caused by vibration or other external factors. This not only enhances the overall stability and service life of the machine but also reduces maintenance costs and reduces failure rates.
- Construction industry:
In architectural engineering, anaerobic thread adhesive is often used in connections between steel structures, viaduct construction, and gas pipeline fixation. With its excellent aging resistance and corrosion resistance, this material can greatly Extend the service life of buildings and improve their safety.
- Electronic and electrical products:
In the field of electronic products, whether it is initial installation or follow-up maintenance services, thread glue can provide good sealing and waterproof performance and protect internal circuits.
How To Use Threadlocker？
- Clean the fasteners that need to be applied with thread glue first to prevent impurities from entering and affecting the locking effect
- Choose the threadlocker glue that suits your model. After opening the lid, cut a small hole in the glue nozzle.
- Tilt the glue bottle, align the head with the thread, continue to squeeze the bottle body, and evenly apply the glue to the fasteners.
- Finally, rotate the installation nut repeatedly to make the glue evenly cover the bolt.
- Wait 24 hours before using the tool to check the locking effect.
It should be noted that each threadlocker has a different disassembly torque, so don’t damage the accessories with too much force.
How Long Does Threadlocker Take To Dry？
Generally, the initial curing time of threadlocker is about 10-30 minutes, while the curing time of high-temperature thread glue is longer. The initial curing takes about 50 minutes, and they can be fully cured in about 24 hours.
The specific curing time is also related to the temperature and humidity of the use environment. For example, low temperature and humidity will delay the curing time. High temperatures will shorten the curing time.
How to Remove Threadlocker？
There are many ways to remove thread locker glue, among which heating with a hair dryer or heat gun is an effective means. When the glue is heated to exceed its tolerant temperature, it will gradually liquefy, making it easier to remove. In addition, chemical solvents are also a feasible option is to soak used fasteners and wait until the glue fails before removing them.
However, for high-strength threadlocker, it is sticky and difficult to remove directly. In this case, it may be necessary to use a torque wrench to destroy it, but doing so may cause damage to the threaded part and screw.
Summary
Well, the above is a detailed introduction to threadlocker. Its corrosion resistance, anti-loosening, waterproofing, oil-proof, and other advantages have been highly relied on by various industries. When choosing a thread sealant, you should choose the appropriate model according to the specific application needs. At the same time, ensure the quality of the product you purchase.

FAQ
Does threadlocker work on plastic?
Threadlocker is not suitable for use on plastic; it is specifically used for metal threaded products.
Threadlocker vs teflon tape: What’s the difference?
Threadlocker is a kind of liquid glue, suitable for high-strength, high-temperature, and other environments. Teflon tape is a tape-shaped anti-loosening sealing product that needs to be wound around the thread to increase friction. It is more suitable for general anti-loosening and sealing needs.
Is thread sealant permanent?
Low-strength thread sealant is removable; high-strength thread sealant forms a permanent seal after curing, making it difficult to disassemble.
Can you use super glue as a thread lock?
No, threadlocker is a liquid adhesive specifically used to seal and lock threads, which is a different category of products from super glue, has different uses and is not used interchangeably.
