Overview
DIN 439 is a thin hex nut with a full internal thread, designed to provide a compact fastening solution. Its height is lower than that of standard DIN 934 nuts, making it suitable for applications where installation space is limited.
Steel versions are available in strength class 5, providing reliable performance under appropriate operating conditions. The nut has a zinc coating that offers additional corrosion protection. Its standard metric thread makes it a versatile fastening element for a wide range of structures and assemblies.
Applications
The DIN 439 strength class 5 zinc-plated thin hex nut is suitable for applications where limited space makes the use of standard-height nuts difficult. Thanks to its reduced height, it provides a reliable threaded connection while maintaining a compact assembly.
The nut is made of steel with a zinc coating that provides basic corrosion protection, making it suitable for use in conditions of moderate humidity. It complies with strength class 5 requirements and can be used in various mechanical systems under appropriate loads.

Equivalent Standards
The DIN 439 strength class 5 zinc-plated thin hex nut is an important component in mechanical connections. Its reduced height allows it to be used in confined spaces.
The nut is made of carbon steel and has a zinc coating that provides additional corrosion protection. DIN 439 is not a direct equivalent of the standard DIN 934 nut because of differences in geometry and nut height. Therefore, when selecting a replacement, it is important to consider the thread diameter and pitch, nut height, strength class, material, and coating type.
Is It Worth Buying?
The DIN 439 strength class 5 zinc-plated thin hex nut is a suitable solution for applications where compact dimensions and reliable threaded connections are important. Its low profile makes installation convenient in confined spaces, while the zinc coating provides additional corrosion protection and improves product durability.
The nut complies with DIN requirements and can be used in various industries, from mechanical engineering to construction. Its precise dimensions and strength class allow the appropriate version to be selected for specific operating conditions.
Where It Is Used
The DIN 439 strength class 5 zinc-plated thin hex nut is used in mechanical engineering, automotive applications, construction, and other technical fields. It is made of steel with a zinc coating that provides additional corrosion protection.
Before purchasing, it is important to check the thread diameter and pitch, nut height, strength class, and coating type. This helps ensure compatibility with the bolts or threaded rods being used and reliable connection performance under appropriate mechanical loads.
