What is EN ISO 3126-0:2018?

EN ISO 3126-0:2018 is a technical standard developed by the International Organization for Standardization (ISO) that specifies the dimensions and tolerances for hexagon steel bolts, screws, and studs. It is part of a series of standards that cover fasteners used in various industries such as automotive, construction, and manufacturing.

The Purpose of EN ISO 3126-0:2018

The purpose of EN ISO 3126-0:2018 is to ensure the interchangeability and compatibility of hexagon steel bolts, screws, and studs produced by different manufacturers. This standard provides uniform specifications for the physical and mechanical properties, dimensional tolerances, and marking requirements for these fasteners.

Key Requirements of EN ISO 3126-0:2018

This standard specifies the following key requirements:

Dimensions: The standard provides detailed information on the dimensions of hexagon steel bolts, screws, and studs, including major diameter, pitch diameter, and minor diameter.

Tolerances: EN ISO 3126-0:2018 defines the acceptable tolerances for the various dimensions of these fasteners to ensure their interchangeability.

Thread Designation: The standard establishes the thread designation for these fasteners, which includes information on thread size, pitch, and flank angle.

Marking: The standard requires manufacturers to mark each fastener with relevant information such as the manufacturer's identification, material grade, and standard designation.

The Benefits of EN ISO 3126-0:2018

Compliance with EN ISO 3126-0:2018 brings several benefits to both manufacturers and end-users. Firstly, it promotes the interoperability of fasteners from different suppliers, reducing the risk of compatibility issues during assembly or maintenance. Secondly, by specifying dimensional tolerances, the standard ensures that the fasteners meet the desired performance requirements. Lastly, clear marking requirements help in identifying and sourcing the correct fasteners for specific applications.

In Conclusion

EN ISO 3126-0:2018 is an important technical standard that provides specifications for hexagon steel bolts, screws, and studs used in various industries. Compliance with this standard ensures interchangeability, compatibility, and quality of these fasteners. Manufacturers and end-users can benefit greatly from implementing these standardized requirements.
