Wire diameter: 2mm, outer diameter: 18mm, free length: 150mm, 2 springs included. The double hook spring is made of high-quality stainless steel, resistant to rust, corrosion, wear, and high temperatures, ensuring long-term durability. This spring is suitable for various applications such as production assembly, experimentation, research and development, and maintenance. It can be widely used in electronics, household appliances, furniture, and machinery. The surface of the spring is uniform and polished to enhance surface finish, providing strong load-bearing capacity. The stainless steel spring allows for greater elastic deformation under load, converting mechanical work or kinetic energy into elastic potential energy. The tension spring is a spiral spring designed to bear axial tension. Our tension springs are manufactured with strict quality control processes, ensuring reliable performance, excellent elasticity, high precision, and a clean appearance. Polished after production for improved finish. This spring is designed to meet everyday application needs. Type: Double Hook. Color: Silver. Free Length: 150mm. Outer Diameter: 18mm.
