Description

Core features of Spring Washer

  1. Elastic anti-loosening: Open deformation generates rebound force, offsetting vibration-induced loosening
  2. Sustained preload: Maintains stable clamping force between bolts and nuts, preventing connection failure
  3. Pressure dispersion: Annular contact surface distributes force evenly, reducing local workpiece stress
  4. Easy installation: Directly fits over bolts, no additional tools or complex operations
  5. Wide compatibility: Matches same-spec bolts/nuts, suitable for machinery, automotive, electrical equipment
