Springs - Extension - Music Wire

Music Wire Extension Springs. Carbon spring steel, zinc plated selection.

  • Helical spring that absorbs and stores energy by resisting a pulling force. When extended, it stores energy, and when released, it redistributes that energy to return to its original, coiled shape.
  • Typically used to provide a pulling force between two objects, often with hooks or loops on either end for attachment.
  • This category includes short and long lengths. An expanded range may be available on special order. Please enquire.
  • Zinc Plated Spring Steel not recommended for applications exceeding 121 Deg C (250 Deg F).
