Extension Spring #29, 1/2"x2-1/8"x.063WG

Extension Spring #29, 1/2"x2-1/8"x.063WG

The 18529 Extension Spring #29 (1/2" x 2-1/8") is a multi-purpose tension spring designed to provide reliable pulling force and return action in mechanical assemblies and equipment mechanisms. Made from durable spring steel, this extension spring is built to handle repeated stretching while maintaining consistent tension. With a 1/2" outside diameter, 2-1/8" free length, and approximately .065 wire diameter, it works well in equipment repairs, shop mechanisms, and general-purpose applications—because when a spring is responsible for pulling things back into place, it’s doing more work than its size suggests.
