DIN 439 04 Low hexagon nut with small step

Overview

DIN 439 is a thin hex nut with a fine thread pitch, designed for reliable connections in confined spaces. Its height is lower than that of standard nuts, helping save installation space. The DIN 439 nut has a full internal thread that provides precise and tight engagement with the corresponding bolt or threaded rod.

Applications

The DIN 439 strength class 4 thin hex nut is a suitable solution for assemblies with limited space where standard-height nuts cannot be used. Its low profile provides a reliable threaded connection while maintaining a compact assembly.

The nut is made of strength class 4 steel, providing appropriate strength and durability under the specified mechanical loads. Thanks to its fine thread pitch, the DIN 439 strength class 4 nut provides precise and tight engagement, making it suitable for various technical applications.

Technical Specifications

Equivalent Standards

DIN 439 strength class 4 is a thin hex nut with a fine thread pitch, designed for reliable connections in confined spaces. When selecting a replacement, it is important to consider the thread diameter and pitch, nut height, strength class, material, and coating type.

Compared with a DIN 934 nut, DIN 439 has a reduced height, making it suitable for applications where compact dimensions are especially important. DIN 934 is not a direct equivalent of DIN 439 because of differences in nut geometry.

Is It Worth Buying?

The DIN 439 strength class 4 thin hex nut with a fine thread pitch is suitable for applications where saving space and maintaining a reliable threaded connection are important. Its compact design makes installation convenient, while the fine thread pitch provides precise and tight engagement.

The nut may be available in different versions and with various protective coatings. For humid or corrosive environments, a version with appropriate corrosion protection should be selected.

Where It Is Used

The DIN 439 strength class 4 thin hex nut with a fine thread pitch is used in mechanical engineering, electronics, equipment installation, and other technical applications. Its low profile makes it suitable for confined installation spaces.

Before purchasing, it is important to check the thread diameter and pitch, nut height, strength class, material, and presence of a protective coating. This helps ensure compatibility with other fastening elements and compliance with the requirements of the specific project.
