ISO 7040 is an international standard that specifies the requirements for high-strength self-locking nuts. This type of nut has a special mechanism that prevents it from loosening under vibration or dynamic loads. Due to its design, the ISO 7040 nut ensures a secure fastening even in demanding operating conditions.
Technical characteristics of ISO 7040
- Operating principle: The self-locking properties of the ISO 7040 nut are achieved through a special internal cone or friction element that, when the nut is tightened, cuts into the bolt thread, creating additional friction.
- Material: Carbon steel, stainless steel, or other alloyed steels are typically used to manufacture ISO 7040 nuts, depending on the requirements for corrosion resistance and strength.
- Coating: Nuts may have various coatings such as zinc, cadmium, or oxidation to protect against corrosion and improve appearance.
- Dimensions of ISO 7040 The dimensions of ISO 7040 nuts are determined by the thread diameter, nut height, and thread pitch. The ISO 7040 standard sets precise tolerances for dimensions to ensure compatibility of the nuts with different types of bolts.
Strength class of ISO 7040
The strength class of an ISO 7040 nut indicates its ability to withstand certain loads without failure. The higher the strength class, the greater the load the nut can withstand.
Fastener group ISO 7040
ISO 7040 nuts belong to the group of fasteners used in various industries, mechanical engineering, automotive industry, and other fields. They are used to connect parts that are subjected to vibration and dynamic loads.
Materials for manufacturing ISO 7040
As mentioned earlier, various materials are used to manufacture ISO 7040 nuts, including carbon steel, stainless steel, and other alloyed steels. The choice of material depends on the operating conditions and requirements for corrosion resistance and strength.
Scope of application of ISO 7040
ISO 7040 nuts are widely used in the following industries:
- Automotive industry: for fastening engine parts, chassis components, and body panels.
- Mechanical engineering: for connecting machine parts and mechanisms operating under vibration conditions.
- Construction: for fastening metal structures.
- Aviation industry: for fastening aircraft parts. ISO 7040 nuts are an important fastening element that ensures the reliability and safety of connections in various industries. Due to their technical characteristics and wide range of applications, they are indispensable in many production processes.
