DIN 439 04 Low zinc hexagon nut with small step

Overview

DIN 439 is a thin hex nut with a fine thread pitch, designed to provide reliable connections in confined spaces. Its height is lower than that of standard nuts, helping reduce the required installation space.

Steel versions may have strength class 4, providing reliable performance under appropriate operating conditions. This version has a zinc coating that provides additional corrosion protection. Thanks to its full internal metric thread, the DIN 439 nut is suitable for a wide range of technical applications.

Applications

The DIN 439 strength class 4 zinc-plated thin hex nut is a suitable solution for assemblies where limited space prevents the use of standard-height nuts. Thanks to its reduced height, it provides a reliable threaded connection while maintaining a compact assembly. The nut is made of steel and has a zinc coating that provides basic corrosion protection, making it suitable for use in conditions of moderate humidity.

Thanks to its fine thread pitch, the DIN 439 strength class 4 nut provides precise and tight thread engagement. It is suitable for automotive applications, mechanical engineering, and other industries where compact dimensions and fastening reliability are important.

Technical Specifications

Equivalent Standards

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

The nut is made of steel with a zinc coating that provides additional corrosion protection. A standard DIN 934 nut has a greater height and is not a direct equivalent of DIN 439, so differences in geometry should be considered when selecting a replacement.

Is It Worth Buying?

The DIN 439 strength class 4 zinc-plated thin hex nut is a suitable choice for connections where compact dimensions and reliability are important. Thanks to its low profile, it can be installed in confined spaces, while the zinc coating provides additional corrosion protection.

The fine thread pitch provides precise and tight engagement with the corresponding bolt or threaded rod. Various available sizes make it possible to select the most suitable option for a specific project without unnecessary specifications.

Where It Is Used

The DIN 439 strength class 4 zinc-plated thin hex nut with a fine thread pitch is used in mechanical engineering, installation systems, metal structure manufacturing, and other technical applications.

Before purchasing, it is important to check the thread diameter and pitch, nut height, strength class, material, and coating type. The zinc coating provides additional corrosion protection and improves product durability under appropriate operating conditions.
