| Parameter | Specification | | :--- | :--- | | | 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). |
Note: While a historical version of DIN 1624 also referred to cold-rolled steel strip, in modern hardware contexts, it almost exclusively refers to the pronged tee nut Fuller Fasteners If you'd like more details, I can help you with: exact drill hole sizes needed for each thread (e.g., M6 or M8) local supplier or online retailer for bulk quantities to alternative blind fasteners like threaded inserts din 1624 standard pdf
While the standard has been officially withdrawn and replaced by European Norms (EN), technical documents and PDF versions of DIN 1624 are still widely sought after for referencing legacy projects, understanding older blueprints, and conducting failure analysis on older components. | Parameter | Specification | | :--- |
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 | | Tolerance Class | Class A (Precision)
