Glossary Hardening of screws

Hardening screws is a process that helps to improve the durability and strength of screws. This is particularly important in applications where screws are exposed to extreme loads.

The hardening process consists of several steps, including heat treatment and quenching. During the heat treatment process, the screw is heated to a certain temperature to change its crystal structure and increase its strength. The exact temperature depends on the type of material the screw is made of and may vary depending on the application.

Once the screw has reached the correct temperature, it is cooled quickly to maintain the strength of the screw. This quenching process can be carried out in various ways, including water, oil or air quenching. The choice of quenching medium again depends on the type of material and can vary depending on the application.

Hardening screws can increase the service life of screws and at the same time improve their strength and resistance to breakage and deformation. However, hardening screws can also have disadvantages, such as reduced ductility and toughness. This means that the screw is more likely to break under extreme loads.

To ensure that screws are properly hardened in a particular application, manufacturers and engineers must consider the exact requirements and specifications of the application. The hardening process must be carried out by trained and experienced personnel to ensure that the screws are hardened professionally and meet the requirements.
