Category Details

A selection of 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).
