When the nut is hammered or pressed into a pre-drilled hole in wood, these prongs bite deep into the material 1001 КРЕПЕЖ This creates a mechanical lock that prevents the nut from spinning
| | Cons | | :--- | :--- | | Clarity: Very clear distinction between drawing qualities and surface finishes. | Obsolete: No longer valid for new designs or contracts. | | Simplicity: Less complex than modern EN standards, making it easier for quick reference on older parts. | Global Compatibility: Largely replaced by EN standards to align with EU regulations. | | Tolerance Specifics: Precision tolerances were well-defined for cold-rolled strip. | Availability: Authentic PDFs are hard to find legally for free; pirated versions may be scanned poorly. | din 1624 standard pdf
According to the standard, these fasteners are generally manufactured from materials that allow for the forming of the prongs without cracking. When the nut is hammered or pressed into
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 , primarily for the manufacture of springs and formed components. | Global Compatibility: Largely replaced by EN standards
While the wood usually fails before the metal nut, the flange must be thick enough to resist "pull-through" forces under high torque. 5. Installation Process
