Why is thread locking important?

Threads are spiral cuts on the surface of screws, nuts, or holes that enable a permanent and stable connection of mechanical components. Due to their simplicity and efficiency, threads play a key role in many industries, such as automotive, construction, aviation, and machinery manufacturing. Their versatility lies in the ability to transfer both axial loads and torsional moments, making them indispensable in the assembly and servicing of industrial devices.

In industry, threads are used in many aspects, from industrial machine construction, hydraulic and pneumatic installations, to delicate electronic devices. In applications requiring exceptional durability, such as in bridge constructions or vehicles, the selection of the appropriate thread type and its protection against loosening are of crucial importance.

Thread securing is fundamental to the safety and durability of connections. Vibrations, temperature changes, and dynamic loads can cause threads to loosen, which increases the risk of equipment failure. Improperly secured screws can lead not only to costly production downtimes but also to threats to the health and safety of workers.

In this context, using advanced thread securing products, such as anaerobic adhesives or thread sealants, becomes standard in many industries. Products like those offered in the Greenmark series guarantee not only the stability of connections but also their resistance to vibrations, temperature fluctuations, and chemical substances. With their ecological formula and excellent technical properties, these modern solutions meet the needs of both heavy and precision industries.

In the following sections of the article, we will look at why thread securing is so important, what methods are most commonly used, and what benefits advanced adhesive products bring.

Problems with Unsecured Threads

One of the most common problems with unsecured threads is their self-loosening. Vibrations and dynamic loads, which occur in industrial machines, vehicles, or mechanical devices, can cause threaded connections to gradually unwind. This process, although invisible at first glance, can have catastrophic consequences, such as machine failures, reduced efficiency, and even serious safety risks. An example of using products to minimize this problem is anaerobic adhesives. Their ability to polymerize in anaerobic conditions makes threaded connections resistant to vibrations and shocks, eliminating the risk of loosening.

Corrosion and Contamination

Unprotected threads are particularly vulnerable to environmental factors such as moisture, salt, or chemicals. This leads to the formation of corrosion, which not only weakens the connection but also makes subsequent disassembly difficult. Additionally, contaminants can block the threading mechanism, leading to costly repairs or replacement of components. Products like thread sealants from the Greenmark® series offer a protective barrier against external factors, extending the lifespan of connections and ensuring their reliability.

Loss of Torque and Leaks

For connections requiring tightness, unsecured threads can lead to a loss of torque, resulting in leaks of working fluids such as oils, fuels, or hydraulic fluids. In the automotive or aviation industries, such leaks pose a particular risk both to system functioning and safety. High-strength anaerobic adhesives, such as B270 Eco, ensure tightness even in harsh conditions, eliminating the risk of leaks and pressure loss in systems.

Benefits of Thread Securing

Secured threads guarantee the stability of connections even in difficult conditions, such as vibrations or dynamic loads. By using anaerobic adhesives or thread sealants, like B243 Eco, it is possible to effectively prevent self-loosening of connections. This is crucial in the automotive industry, where vibrations from the engine or chassis could cause dangerous failures. These adhesives act like invisible locking screws, stabilizing the structure and minimizing the risk of unwinding.

Corrosion is one of the greatest threats to threads exposed to atmospheric factors such as moisture, salt, or chemicals. Protective products, such as Greenmark ecological adhesives, create a protective layer that effectively isolates threads from harmful factors. As a result, the structure of the connections is preserved, and their durability is extended. Additionally, these products have high chemical resistance, making them ideal for use in the petrochemical or maritime industries.

Properly secured threaded connections have a significantly longer lifespan compared to unsecured ones. Anaerobic adhesives of varying strength levels – low, medium, or high – adapt to the specifics of the application, from easily removable screws to those that must withstand extreme loads. Furthermore, securing prevents mechanical damage due to friction, which is particularly important in industrial machines and large-scale devices.

Key benefits:

• Safety: Securing threads protects against potential failures that could jeopardize people and equipment.

• Cost Savings: Reduction in repair and replacement costs due to increased durability of connections.

• Ecology: Using eco-friendly adhesives, such as Greenmark® products, supports environmental protection without compromising performance.

Securing threads not only eliminates the problems described in the previous section but also brings long-term benefits for both equipment and industrial processes. As a result, threaded connections become reliable in any situation.

Screws and threads in engine systems, suspensions, or exhaust systems are exposed to extreme mechanical loads and vibrations. The use of anaerobic adhesives, such as B243 Eco, eliminates the risk of loosening connections, even under dynamic loads. Furthermore, these adhesives are resistant to fuels, oils, and high temperatures, making them ideal for protecting engine and transmission components.

Aviation and space exploration require the highest quality and reliability of fastenings, as every threaded connection is critical for flight safety. Anaerobic adhesives used in this industry, such as products meeting Airbus ECS-L 2274 and Boeing BMS8 45 Type II standards, offer not only excellent vibration resistance but also protection against corrosion in extreme environmental and thermal conditions. As a result, thread locking is used in hydraulic systems, structural parts, and propulsion elements of aircraft.

In industrial and energy machinery, thread locking enhances efficiency and durability. Threaded connections in wind turbines, generators, or manufacturing machinery must withstand high loads and harsh environmental conditions. Products such as Greenmark eco-friendly adhesives provide long-lasting protection against corrosion and loosening, reducing the risk of costly breakdowns and downtime.
