Threadlockers are chemical adhesives used in threaded assemblies such as nuts and bolts. Their purpose is to securely lock the assembly in place in order to ensure that no loosening or backing out happens.
When it comes to using a threadlocker, it’s very simple and does not require complicated tools. Just a small amount or one drop of the chemical is needed to be applied to the front threads of the bolt. It will then cover the female thread once the bolt mates with the retaining piece. Given the different types of threadlockers as they come in various strengths, colours, and grades, it is important that you know which is the right one for your application.
In terms of bond and wicking properties, there are four major options for a threadlocker: low, medium, high, and wicking. Needless to say, the low variant offers low strength bonds that can be disassembled with the use of hand tools only. It is ideal for assemblies that need secure fastener holding in place but have to be disassembled from time to time. Conversely, a medium threadlocker is ideal to be used for crucial joints that may require disassembly but very rarely.
As its name suggests, high strength threadlocker is perfect for use in assemblies that require permanent bonds and it can only be disassembled using heat and power tools. This is why it must not be used on a threaded assembly that has to be taken apart. Otherwise, the components will be damaged. Lastly, the wicking variant of threadlockers are used for retrofitting thread lockers into existing assemblies as well as in addressing special challenges of the manufacturing process.
Regardless of the strength variant of threadlocker you need, they are proven effective in sealing leaks and resisting loosening of threaded fasteners caused by impacts and vibration. They naturally prevent corrosion by keeping fluids out of the thread and providing a barrier against corrosion.
