DIN 439 04 Low zinc hexagon nut

Overview

DIN 439 is a thin hex nut with a full internal thread, designed for convenient installation in applications where space is limited. Its reduced height makes it suitable for assemblies where compact dimensions are important.

Steel DIN 439 nuts may have strength class 4, providing reliable performance under appropriate operating conditions. Different versions are available, including zinc-plated nuts that provide additional corrosion protection. The hexagonal shape and full internal thread allow use with corresponding metric threads of standard or fine pitch.

Applications

The DIN 439 strength class 4 zinc-plated thin hex nut is a suitable solution for confined spaces where standard-height nuts may be difficult to use. Thanks to its reduced height, it provides a compact threaded connection and is widely used in mechanisms and structures where saving space is important.

The nut is made of steel and has a zinc coating that provides basic corrosion protection. It complies with established strength requirements and is suitable for general technical applications. The nut dimensions comply with DIN requirements, ensuring compatibility with corresponding fastening elements.

Technical Specifications

Equivalent Standards

The DIN 439 strength class 4 zinc-plated thin hex nut is an important component in mechanical connections. Its reduced height makes it suitable for applications with limited installation space.

ISO 4035 may be considered as a possible equivalent, but when selecting a replacement, it is essential to check the thread diameter and pitch, nut height, material, strength class, and coating type. DIN 439 is not a direct equivalent of DIN 934 because the standards specify different nut geometries, particularly in terms of nut height.

Is It Worth Buying?

The DIN 439 strength class 4 zinc-plated thin hex nut is suitable for applications where compact dimensions and reliable threaded connections are important. Its low profile makes it convenient for use in confined spaces, while the zinc coating provides additional corrosion protection.

The nut is available in various sizes, allowing the most suitable option to be selected for a specific project. When the thread diameter, pitch, and other specifications are correctly matched, DIN 439 is a reliable solution for a wide range of technical applications.

Where It Is Used

The DIN 439 strength class 4 zinc-plated thin hex nut is used in mechanical engineering, electrical equipment, construction, and other applications requiring a compact threaded connection. Thanks to its reduced height, it is suitable for installation in confined spaces.

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