Stainless Steel Hex Serrated Flange Spinlock Nut DIN6923 — M3–M12
The DIN6923 stainless steel hex serrated flange spinlock nut is a high-grip variant of the standard flange lock nut, featuring a more aggressive serration pattern that provides enhanced anti-rotation performance in high-vibration environments. The integrated serrated flange eliminates a separate lock washer, reducing part count and assembly time while delivering reliable anti-loosening performance in electronics, automotive, and industrial applications.
Key Specifications
| Parameter | Value |
|---|---|
| Material | 304 Stainless Steel |
| Standard | DIN6923 / ISO 4161 |
| Thread Type | Metric coarse |
| Size Range | M3, M4, M5, M6, M8, M10, M12 |
| Flange Type | Serrated spinlock (high-grip anti-rotation) |
| Drive | Hex (spanner / socket) |
Why Choose Serrated Flange Spinlock Nuts?
- High-grip serration pattern — aggressive serrations provide enhanced anti-rotation performance vs standard flange nuts; ideal for high-vibration environments
- Spinlock design — serrations engage immediately on tightening; no additional locking element required
- Integrated flange — eliminates separate lock washer; larger bearing surface distributes load and prevents pull-through
- 304 stainless steel — corrosion-resistant for electronics, outdoor, and industrial applications
- DIN6923 standard — compatible with all standard metric coarse thread bolts M3–M12
Typical Applications
- High-vibration industrial machinery and equipment fastening (M6–M12)
- Automotive chassis, suspension, and drivetrain assembly (M8–M12)
- Electronics enclosure and control cabinet assembly (M3–M6)
- 3D printer and CNC machine frame assembly (M3–M6)
- Robotics and drone frame fastening (M3–M6)
- HVAC and ventilation equipment mounting (M6–M10)
Compatible With
- Standard metric coarse thread bolts and cap screws M3–M12
- Spanner / socket: M3=5.5mm, M4=7mm, M5=8mm, M6=10mm, M8=13mm, M10=17mm, M12=19mm AF
- Aluminium extrusion T-slot bolts (M3, M4, M5, M6)
Package Contents
- DIN6923 hex serrated flange spinlock nuts in selected size and quantity (per variant)
Frequently Asked Questions
- Q: What is a spinlock nut?
- A: A spinlock nut is a type of serrated flange nut with an aggressive serration pattern designed to grip the mating surface immediately on tightening, providing high anti-rotation resistance. The term “spinlock” refers to the nut’s resistance to spinning loose under vibration.
- Q: How does this differ from a standard DIN6923 flange nut?
- A: The spinlock variant has a more aggressive serration geometry that provides higher grip force on the mating surface. It is preferred in high-vibration applications where standard serrated flange nuts may not provide sufficient anti-loosening performance.
- Q: Can these be reused?
- A: Yes. Unlike nyloc nuts, serrated flange spinlock nuts can be reused multiple times. However, if the mating surface serration marks are worn smooth, the anti-loosening effectiveness may be reduced on subsequent uses.
