Frequently Asked Questions

What is threadlocker used for?

add

Threadlocker sealant is used in aviation to secure gaps between threads on bolts, screws, and other threaded fasteners to lock them in place and prevent loosening caused by vibrations. Another benefit of the threadlocker sealant is that it provides corrosion protection, which serves to prolong the lifespan of critical aircraft components and equipment that are exposed to extreme aerospace environments.

How to use threadlocker?

add

The application of threadlocker sealant is simple—the liquid or paste formula is applied directly to clean, grease-free threaded components. Threadlockers typically have a rapid cure time, meaning that within minutes, the sealant hardens to create a strong, reliable seal.

What are some of the threadlocker types?

add

Threadlocker is available in a variety of strengths. High-strength threadlockers can be used to create permanent bonds. Low-strength threadlocker sealants can be used in applications where fasteners need to be easily disassembled with standard hand tools for regular servicing tasks.
