Product Features & Engineering Logic
| Key Feature | Technical Specification | Operational Benefit (Trust Driver) |
| Conical Geometry | Disc spring shape per DIN 6796. | Maintains constant pressure by compensating for thermal expansion and structural settling. |
| Material Base | Premium Spring Steel (C60S / 51CrV4). | Ensures excellent elastic recovery and long-term fatigue resistance. |
| Surface Treatment | Dacromet (Zinc Flake Coating). | Eliminates hydrogen embrittlement risks; ideal for high-strength fasteners. |
| Static Loading | Optimized for static bolting. | Prevents loss of preload in heavy machinery and structural steelwork. |
FAQs
Q1: What is the difference between DIN 6796 and DIN 2093 (Disc Springs)?
DIN 6796 is specifically designed for bolting applications (static or occasional dynamic loads) to maintain preload. DIN 2093 is intended for precision mechanical spring applications with frequent dynamic cycles.
Q2: Can Dacromet DIN 6796 washers be used in outdoor environments?
Yes. The Dacromet coating provides an exceptionally high salt spray resistance, making it suitable for wind power, telecommunications towers, and outdoor infrastructure.
