Material Our tension springs are made of 304 stainless steel. Precise Size Each spring features a wire diameter of 2 mm (0.079 inches), an outer diameter of 20 mm (0.79 inches), and a length of 160 mm (6.3 inches). This precise size combination ensures a strong, secure fit for various applications, offering dependable performance every time. Strength and Elasticity Equipped with strong hooks and a uniform pulling force, these springs are built to handle tough tasks. The loops at both ends provide firm attachment points, while the spring's elasticity offers powerful resistance and reliable resilience under tension. Wide Application Range From manufacturing to research, automotive to aerospace, tension springs like these are widely used in electronics, tools, toys, construction, and machinery. Their versatility makes them essential for both commercial and projects. Use Scenarios Electronics and enclosures: suitable for panel doors, battery compartments, or access latches that require a reliable or tension mechanism. Tools, toys, and construction: useful for lids, covers, or pulltorelease mechanisms that need firm attachment and consistent tension. Automotive and machinery: applicable to small linkages or retractable components where a steady pulling force and durable attachment points are needed.
