Extension Spring #89, 15/32"x2-1/4"

The 18589 Extension Spring #89 (15/32" x 2-1/4") is a durable spring steel extension spring designed to provide reliable tension and return force in mechanical assemblies. Built from high-quality spring steel, this spring is engineered to stretch under load and return components to their original position once tension is released. With a 15/32" diameter and 2-1/4" length, it’s well suited for equipment repairs, mechanical linkages, and general shop applications where dependable tension is required. In short, it’s a hardworking little spring that keeps parts pulled into place instead of wandering off on their own.
