Nut DIN 439 M20 04

Overview

DIN 439 is a thin hex nut with a full internal thread and reduced height, making it suitable for applications where installation space is limited.

Steel versions may have strength class 4, providing reliable performance under appropriate operating conditions. This particular version has no protective coating. The nut has a standard metric thread, allowing it to be used in various existing structures and mechanisms.

Applications

The DIN 439 strength class 4 thin hex nut is a suitable solution for applications where space is limited but a reliable threaded connection is required. Its compact design allows it to be used where standard-height nuts are unsuitable.

Made of steel, it provides strength and resistance to mechanical loads within the corresponding technical limits. The DIN 439 strength class 4 nut is a reliable fastening element for technical projects where compact dimensions and connection stability are especially important.

Technical Specifications

Equivalent Standards

The DIN 439 strength class 4 nut 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, material, strength class, and presence of a protective coating.

The DIN 439 nut has a lower height than a standard 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.

Is It Worth Buying?

The DIN 439 strength class 4 thin hex nut is suitable for applications where saving space and maintaining a reliable threaded connection are important. Its compact design makes installation convenient in confined spaces.

This version is made of steel and has no protective coating. Therefore, when used in humid or corrosive environments, additional corrosion protection should be considered, or a nut with an appropriate protective coating should be selected.

Its precise dimensions and compliance with DIN requirements make it possible to select a suitable version for a specific project and ensure compatibility with corresponding bolts or threaded rods.

Where It Is Used

The DIN 439 strength class 4 thin hex nut is used in various industries, including mechanical engineering, automotive applications, construction, and industrial equipment. It is suitable for structures requiring a compact threaded connection.

Before purchasing, it is important to check the thread diameter and pitch, nut height, material, strength class, and presence of a protective coating. This helps ensure compliance with the requirements of the specific project and compatibility with the bolts or threaded rods being used.
