DIN 439 A2 Low hexagon nut with small step and left-hand thread

Overview

DIN 439 is a thin hex nut with a full internal thread, designed for convenient installation in confined spaces thanks to its compact height.

Steel versions may have strength class 4, providing reliable performance under appropriate operating conditions. This version has a zinc flake coating that provides additional corrosion protection. Its hexagonal shape and full internal thread allow convenient installation and removal, making the nut a versatile solution for various technical applications.

Applications

The DIN 439 strength class 4 thin hex nut with a zinc flake coating is suitable for applications where limited space prevents the use of standard-height nuts. Thanks to its low profile, it provides a reliable threaded connection while maintaining a compact assembly.

The nut is made of steel and has a zinc flake coating that provides additional corrosion protection. It complies with strength class 4 requirements and is suitable for use in various mechanisms and assemblies under appropriate mechanical loads.

Technical Specifications

Equivalent Standards

DIN 439 strength class 4 is a thin hex nut for which ISO 4035 may be considered as a possible equivalent. When selecting a replacement, it is important to consider the thread diameter and pitch, nut height, strength class, material, and coating type.

A DIN 439 nut has a lower height than a DIN 934 nut, making it suitable for confined installation spaces. DIN 934 is not a direct equivalent of DIN 439 because of differences in nut geometry.

This version is made of steel with a zinc flake coating that provides additional corrosion protection. DIN 439 combines compact dimensions with a reliable threaded connection.

Is It Worth Buying?

The DIN 439 strength class 4 thin hex nut with a zinc flake coating 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 flake coating provides additional corrosion protection and contributes to longer product service life.

Thanks to precise dimensions and compliance with DIN requirements, the nut provides reliable engagement with corresponding bolts or threaded rods. When selecting a specific version, it is important to consider the thread diameter and pitch, strength class, and coating type.

Where It Is Used

The DIN 439 strength class 4 thin hex nut with a zinc flake coating is used in mechanical engineering, automotive applications, construction, industrial equipment, and other technical fields.

Before ordering, it is important to check the thread diameter and pitch, nut height, strength class, material, and coating type to ensure compliance with the requirements of the specific project and compatibility with the bolts or threaded rods being used. The zinc flake coating provides additional corrosion protection and improves product durability under appropriate operating conditions.
