Title: The Ultimate Guide to DIN 1624: Steel Flat Wire Properties, Applications, and the PDF Question
Introduction
In the world of precision engineering, the smallest components often carry the biggest responsibilities. When it comes to flat steel wire used for springs, clips, and formed parts, one German standard has stood the test of time: DIN 1624. din 1624 standard pdf
If you have been searching for a "DIN 1624 standard PDF," you are likely either specifying material for a high-stress component or trying to decode an old drawing. This post will explain what DIN 1624 covers, its chemical and mechanical requirements, its current status (active or superseded), and—most importantly—where to legally find the official standard.
What is DIN 1624?
DIN 1624 is a German industry standard titled "Steel Flat Wire; Tolerances on Height and Width; Shape and Mass." It specifically defines the technical delivery conditions for uncoated, cold-rolled flat steel wire intended for cold forming, primarily for the manufacture of springs and formed components.
Unlike general flat steel, DIN 1624 focuses on tight tolerances on the cross-section (height and width), edge condition (rounded or square), and specific mechanical properties required for reliable bending and spring performance.
Key Technical Specifications of DIN 1624
If you are working with this standard, you need to know these critical parameters:
| Parameter | Specification | | :--- | :--- | | Material Groups | Unalloyed spring steels (e.g., C55S, C67S, C75S, C85S) and micro-alloyed steels. | | Width Range | Typically 2 mm to 125 mm (depending on thickness and rolling method). | | Height (Thickness) Range | Typically 0.2 mm to 10 mm. | | Tolerance Class | Class A (Precision) and Class B (Standard). Class A tolerances are roughly half of Class B. | | Edge Condition | Defined as "rolled" (rounded) or "sheared" (square-cut). | | Surface | Cold-rolled, usually uncoated (may be lightly oiled for corrosion protection). |
Mechanical Requirements (Example for C67S per old DIN 1624)
Is DIN 1624 Still Valid? Important Status Update
This is the most critical part of your research. DIN 1624 was withdrawn (superseded) in 1997.
Why? Germany harmonized many of its steel standards with European (EN) and International (ISO) standards. DIN 1624 was replaced by several newer standards. You should check the current counterparts:
Note: If you find a "DIN 1624 PDF" online from a non-standard source (like a document sharing site), it is very likely the historical, withdrawn version. It can be useful for legacy part reproduction, but you should not use it for new product design without checking EN 10132-3.

The DIN 1624 standard is a widely referenced specification in the manufacturing industry, primarily covering two distinct areas: cold-rolled unalloyed steel strip and furniture "T-nuts" (driving nuts). While the standard for steel strip has been technically superseded by European norms, it remains a vital reference for legacy technical data and component manufacturing. Overview of DIN 1624
In the German standardization system, DIN 1624 historically defined the technical delivery conditions for cold-reduced mild unalloyed steel strip with widths up to 650 mm and thicknesses up to 6 mm. However, in modern fastener catalogs, "DIN 1624" is most commonly used to describe four-prong T-nuts, which are essential hardware in the furniture and woodworking industries. Technical Specifications for DIN 1624 T-Nuts
T-nuts produced according to this standard are designed to provide a threaded steel socket in wooden surfaces. The typical configuration includes a flat base with four sharp prongs that "bite" into the wood to prevent rotation during assembly. Specification Common Sizes M4, M5, M6, M8, M10, M12 Material Zinc-plated carbon steel or A2/A4 stainless steel Thread Type Standard Metric Field of Use Furniture assembly, cabinetry, and wooden structures Steel Strip Delivery Conditions (Legacy)
Before its partial withdrawal, the standard categorized mild steels into various grades (e.g., St 2, St 3, St 4) based on their mechanical properties and surface finishes:
Grades: Common grades like St 2 (1.0330) and St 4 (1.0338) are suitable for forming and surface refinement.
Surface Finishes: Options include bright (RPG), matt (m), and surfaces intended for electroplating (UG).
Equivalent Standard: For current projects requiring cold-rolled strip, DIN EN 10139 is the modern replacement. Where to Find the DIN 1624 Standard PDF What it is: DIN 1624 is a German
