Category Details

A selection of Stainless Steel Extension Springs. 300 gradd stainless steel selection, including 303, 304 and 316.

  • 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.
  • 302 Stainless springs not recommended for applications exceeding 260 Deg C (500 Deg F).
  • 302 stainless steel is slightly magnetic.
