NFE25-511 A2 304 Stainless Steel Disc Spring Serrated Conical Lock Washer Elastic Gasket M3–M16
NFE25-511 standard 304 stainless steel disc spring (Belleville) serrated conical lock washers. Combines the spring preload of a Belleville disc spring with the tooth grip of a serrated lock washer — providing the highest anti-loosening performance of any standard lock washer type. The conical spring maintains bolt preload under thermal cycling and vibration, while the serrated teeth prevent rotation.
Key Specifications
| Material | 304 Stainless Steel |
|---|---|
| Grade | A2 |
| Standard | NFE25-511 (French standard, widely used in aerospace and automotive) |
| Type | Disc spring serrated conical lock washer (Belleville + serrated) |
| Size Range | M3, M4, M5, M6, M8, M10, M12, M16 |
| Function | Spring preload + serrated tooth anti-rotation |
Why Choose NFE25-511 Disc Spring Lock Washers?
- Dual anti-loosening mechanism — Belleville spring maintains preload + serrated teeth prevent rotation; highest performance of any standard lock washer
- Thermal cycling resistance — spring preload compensates for bolt relaxation under temperature changes
- 304 stainless steel — corrosion-resistant for electronics, automotive, and outdoor applications
- NFE25-511 standard — widely specified in aerospace, automotive, and precision engineering
- M3–M16 range — covers electronics to medium industrial assembly
Typical Applications
- Aerospace and aviation fastening (NFE25-511 is an aerospace standard)
- Automotive engine and drivetrain fastening (thermal cycling resistance)
- Electronics enclosure fastening in high-vibration environments
- Precision instrument and optical equipment fastening
- Industrial machinery fastening requiring maximum anti-loosening
FAQ
Q: What is the difference between NFE25-511 and standard split lock washers?
A: NFE25-511 combines a Belleville disc spring (maintains bolt preload) with serrated teeth (prevents rotation). Standard split lock washers only provide spring action without serrated teeth. NFE25-511 provides significantly higher anti-loosening performance, especially under thermal cycling.
