Metric screws are fasteners characterized by a thread with dimensions defined according to the metric system, i.e. millimetres. Thanks to their precision and standardization, they are essential in multiple fields, including mechanical and automotive industries. However, they are also used in several other industries, such as electronics, machine building and civil engineering. In this article, we will explore the regulations and reference standards for metric screws, analysing their characteristics, applications and advantages.
History and development
The metric system was introduced in the late 18th century, but it was not until the 20th century that metric screws became an international standard. The standardization of metric screws has enabled greater interoperability and exchange between industries in many countries. ISO (International Organization for Standardization) standards have played a key role in defining the technical specifications for metric screws, making them an essential and universally accepted component.
Technological evolution
Metric screws have been developing over time thanks to innovations in terms of materials and manufacturing techniques. Nowadays, these screws are made from high-strength steels, special alloys and composite materials that extend their life and give them superior resistance to mechanical stress and corrosion. Furthermore, modern threading technologies guarantee greater precision, reducing the risk of loosening and improving the safety of the joints.
Reference regulations and standards
Metric screws are regulated by several international standards, which define dimensions, tolerances and mechanical properties. The main reference standards include:
ISO 68-1: This standard specifies the geometric characteristics of basic metric threads.
ISO 261: This standard defines the standard pitches of metric threads.
ISO 965-1: This standard describes tolerances for metric threads.
DIN 13: This standard is very important for metric threads, and it’s specific to the European market.
These standards ensure that metric screws are compatible with one another, regardless of manufacturer or production area. Specifications include nominal diameter, thread pitch, length and mechanical properties, ensuring the screws meet safety and performance requirements.
Modern applications
Metric screws are used in a wide range of modern applications and industries.
Mechanical industry: Metric screws are used in industrial machineries, precision equipment and measuring instruments. They ensure a solid and reliable connection.
Automotive industry: Metric screws are essential to assemble vehicles, from chassis structures to engine components. The standardization of metric screws makes mass production and maintenance easier.
Electronics: Metric screws are used to assemble electronic devices, ensuring precision and stability in connections.
Constructions: Metric screws are used in metal structures, bridges and buildings, where resistance and precision are crucial.
