Description
High Strength DIN137A Domed Spring Washer
DIN137 Curved / Wave Spring Washer
The DIN137 Saddle Spring Washer (also known as Curved Spring Washer or Domed Spring Washer) is a high-quality German-standard fastening component designed to prevent bolt and nut loosening under vibration and dynamic loads.
Key Features
  • Excellent Anti-Loosening Performance - The curved/wave design provides consistent spring force that maintains preload between bolted connections, effectively preventing loosening caused by vibration and shock loads
  • Precision Manufacturing - 100% dimensional inspection ensures outer diameter tolerance ±0.05mm, thickness ±0.02mm, and parallelism ≤0.03mm
  • Superior Material Quality - Made from quenched and tempered spring steel (65Mn/50CrV4) or high-grade stainless steel, delivering hardness of HRC 40-51 and reliable elastic recovery
  • Wide Application Range - Suitable for automotive, machinery, construction, electronics, aerospace, railway, marine, and food processing industries
  • Multiple Finishes - Available in plain, black oxide, zinc plated (yellow/blue-white), Dacromet, and custom colors to meet various environmental and aesthetic requirements
  • Corrosion Resistance - Stainless steel A2/A4 options provide excellent resistance to rust and corrosion in marine, chemical, and outdoor environments
