Extension Spring #172

The 18683 Extension Spring #172 (SRM172) is a long, light-duty extension spring designed to provide consistent tension and dependable return force in mechanical assemblies and equipment. Made from durable spring steel, it is built to handle repeated stretching and recoil while maintaining reliable performance. With a 1/4 in spring diameter, 10-1/2 in body length, and .030 wire gauge, this spring is ideal for applications requiring extended travel and light tension—because sometimes a longer spring is exactly what keeps everything pulling together properly.
