Product Description
External Serrated Lock Washers with Anti-Loosening Mechanism
External serrated lock washers provide superior anti-loosening performance through their unique mechanical design, featuring radial external teeth that embed into contact surfaces to create secure mechanical interlocks.
Structural Design & Anti-Loosening Mechanism
Tooth Configuration: 16-32 radial external serrations
Tooth Angle: 60°-90°
Tooth Height: 0.3-1.5mm
- Friction Enhancement: Micro-interlocking increases friction coefficient to resist vibration and torque-induced loosening
- Elastic Compensation: Absorbs dynamic loads and maintains stable clamping force under fluctuating conditions
- Stress Dispersion: Evenly distributes concentrated stress across connection surfaces to prevent fatigue failure
Material Specifications
| Material | Properties | Applications |
|---|---|---|
| Carbon Steel | HRC 36-43 hardness, cost-effective, high strength | General industrial environments |
| Stainless Steel (304/316) | Excellent corrosion resistance, 5,000+ hours salt spray testing | Humid, chemical, marine environments |
| Brass | Good electrical conductivity, prevents sparking | Electrical equipment |
| Spring Steel (65Mn) | High elasticity, superior vibration resistance | Long-term vibration scenarios |
Surface Treatments & Performance
- Zinc Plating: Basic corrosion protection, 200+ hours salt spray resistance
- Phosphating: Enhanced friction coefficient for high-torque applications
- Black Oxide/Passivation: Improved appearance and surface consistency
- Dacromet: Environmentally friendly coating, 1,000+ hours salt spray resistance
Technical Specifications
