From its origins in the automotive industry to its application in agricultural machinery, solar parks, and other industries
Factors such as vibrations, thermal cycles, exposure to fluids, and harsh environmental conditions make the in-service behavior of a threaded joint just as important as the initial tightening torque.
In this context, solutions such as Precote®, originally developed to meet the demanding requirements of the automotive industry, provide significant added value to fastening systems by improving their performance and long-term reliability.
The Origin of Precote® in the Automotive Industry
The automotive industry was one of the first to systematically address problems associated with:
- In-service loosening
- Loss of sealing
- Variability in assembly processes
The combination of constant vibrations, repeated thermal cycles, exposure to oils and other fluids, along with high production volumes, drove the development of solutions capable of ensuring fastening performance beyond the initial tightening torque.
In this scenario, thread-integrated locking and sealing systems emerged as a reliable alternative to reduce failures, improve process repeatability, and raise overall quality standards.
What Precote® Brings to Industrial Fastenings
Precote® allows additional functional properties to be incorporated directly into the screw or fastening element, without the need for external components or additional in-line processes.
Its main benefits include:
- Controlled Thread Locking: Helps maintain joint stability under vibration and dynamic loads.
- Sealing Against Liquids and Gases: Reduces the risk of leaks and the ingress of contaminants.
- Improved Assembly Repeatability: Reduces variability between joints and enhances overall process quality.
These characteristics translate into a direct improvement in fastening system reliability and a reduction in failures throughout the component’s service life.
Precote® in Agricultural Machinery
In agricultural machinery, fasteners operate under severe vibrations, humidity, dust, and exposure to fertilizers, often in continuous field-use conditions. In this context, joint stability is essential to prevent loosening and premature failures, and solutions such as Precote® help improve the reliability of critical components without modifying the overall design.
Precote® in Solar Parks
In photovoltaic parks, fasteners and structures are exposed to permanent outdoor conditions, daily thermal cycles, and long periods without maintenance. Effective sealing against moisture ingress and fastening stability are key to ensuring system longevity, and the use of integrated locking and sealing solutions contributes to increased durability and reliability in these applications.
What to Consider When Choosing a Fastening System
Selecting the appropriate fastening system depends on the operating environment, applied loads, vibrations, and service conditions of the assembly.
To evaluate a specific application and define the most suitable solution, it is essential to have accurate technical information about the component, the environment, and the system requirements.
