Application of brake products on threaded parts.

Applying a brake product to a thread is crucial to ensure the tightening and securement of mechanical assemblies.

What is a brake product?

Brake products are adhesive substances that are applied to the threads of bolts and nuts.
When tightened, these brake products create a chemical or mechanical bond between the threaded surfaces, which helps to keep the mechanical parts in place and prevent them from loosening.

Why apply this product?

Applying brake products on threaded parts, such as bolts or nuts, is a technique used to prevent these components from unintentionally loosening.
Parts that are prone to loosening, such as wheel bolts or engine fasteners, can pose serious safety issues if they come loose during use. Applying brake products on the threads is thus an important preventive measure to ensure that these parts remain securely fastened.

What can cause loosening?


When parts are subjected to repeated vibrations, they can loosen over time, even if they were properly tightened initially. This can be particularly common in applications where parts experience constant movement, such as in engines, industrial machinery, vehicles, etc.

Cyclic loads.

Cyclic loads, such as temperature fluctuations or loading and unloading cycles, can also lead to the loosening of threaded parts. When parts are subjected to these cyclic loads, the material can deform or expand, which can affect the thread tension and result in the loosening of the parts.


Corrosion can weaken threads and reduce the tension between parts, leading to loosening. Corrosive environments, such as coastal areas or industrial facilities, can accelerate this process.

It's important to choose the appropriate type of braking or bonding based on the characteristics of the parts being assembled, as well as the stresses the assembly will undergo
