Din 1624 Standard Pdf

Before you spend time hunting for a withdrawn , contact your steel supplier. Most suppliers (like ThyssenKrupp, Salzgitter, or ArcelorMittal) have internal conversion charts. Tell them: "I have a drawing calling for DIN 1624 - St 3. What EN 10139 grade do you recommend as equivalent?" Typically, DC03 (EN 10139) is the direct replacement for St 3.

When compiling manufacturing documentation or technical submittals, referencing secondary tables may not suffice for strict quality assurance audits.

For hardwoods: Use a clamping tool, vise, or a sacrificial bolt and washer configuration to pull the tee nut smoothly into the wood. This prevents the prongs from bending against dense grain.

The reason for withdrawal is harmonization. In the early 1990s, Germany adopted a wave of European (EN) standards to replace national standards. The content of DIN 1624 was merged and superseded by (Steel wire for mechanical springs – Part 1: Patented cold-drawn unalloyed spring steel wire).

Used for aesthetic purposes where the hardware must remain hidden or blend seamlessly with dark woods or black painted surfaces. Industrial Applications

The standard outlines mild, unalloyed steel grades that balance high ductility with sufficient tensile strength. Standard classifications include: Before you spend time hunting for a withdrawn

Note: Minor dimension variations exist based on manufacturing tolerances and the specific material thickness of the base metal flange. Material Composition and Surface Finishes

DIN 1624, titled "Steel Wire for Mechanical Springs; Technical Conditions of Delivery" (originally Massive Federn aus Stahldraht ), was a German standard published by Deutsches Institut für Normung (DIN). It specifically covered unalloyed or low-alloy steel wire, cold-drawn, intended for the manufacture of mechanical springs—typically those subject to static or moderately dynamic loads.

The standard defined specific surface requirements suitable for painting or plating: What EN 10139 grade do you recommend as equivalent

The wide flange distributes the clamping load over a larger surface area, preventing the fastener from pulling through softwoods, hardwoods, or composite materials under high axial tension. Technical Specifications and Dimensions

It is vital for engineers and procurement officers to note that . As part of the European harmonization of standards, DIN 1624 was replaced in the late 1990s and early 2000s.

: Chemical composition and permissible steel grades.

In the fasteners industry, DIN 1624 defines the dimensions and technical requirements for "Tee Nuts with Prongs," which are driven into wood to create a threaded connection.

Proper installation prevents the tee nut from spinning or backing out of the material.
