Feature: Both ends are ground flat and tight. Surface strengthening treatment.
DIY Supplies: Metalworking Spring General use spring for toys equipment tools etc, can also used for a variety of household applications. Uniform pitch: CNC technology processing and production calculations are precise, the pitch is uniform and the force is stable, and there is a good force structure. Smooth surface: rigorous material selection, real materials make the surface of the spring very smooth, more durable and corrosion-resistant, and increase the life of the spring. Durable: strong repositionability, strong fatigue resistance, durable and good corrosion resistance, longer life.
