China Coil Spring Lock Washers Manufacturer, Supplier, Factory

When it comes to securing fasteners in demanding applications, the right choice of washers can make all the difference. Our high-performance Light Type Spring Lock Washers are engineered for situations where weight and space are critical constraints, providing reliable tension without adding significant bulk. For more standard applications requiring robust locking force, our Single Coil Spring Lock Washers offer a perfect balance of strength and durability. As a foundational category, our range of Spring Lock Washers encompasses various designs to prevent loosening under vibration and thermal cycling. Specifically, our Coil Spring Washers utilize a helical coil design to apply a consistent spring force, maintaining clamp load integrity in dynamic environments.


The fundamental principle behind the Coil Spring Lock Washers is their ability to act as a spring, compensating for loosening caused by vibration, thermal expansion, and material relaxation. When a fastener is tightened, the Coil Spring Lock Washer compresses. This compression stores energy, creating a continuous spring force that pushes the nut and bolt threads together, thereby maintaining tension and preventing the fastener from rotating loose. This makes Coil Spring Lock Washers indispensable in assemblies subject to shock, vibration, or significant temperature fluctuations. Their helical coil form provides a larger range of deflection compared to some other lock washer types, allowing for better absorption of movement and stress.

Key Specifications of Our Coil Spring Lock Washers

  • Material: High-Carbon Steel (Grade 1060-1090), Stainless Steel (AISI 302/304/316), and other alloys upon request.
  • Finish: Plain (Self-Color), Zinc Plated, Galvanized, or Phosphate Coated for enhanced corrosion resistance.
  • Standards: Manufactured to comply with DIN 137, ANSI B18.21.1, and other international standards.
  • Operating Temperature: Performance is maintained across a wide range, typically from -20°F to +450°F (-29°C to +232°C), depending on material.
  • Reusability: Designed for multiple uses, though inspection for fatigue or deformation is recommended after significant stress cycles.
