[Specification] Wire diameter 2mm/0.79in, outer diameter 18mm/0.71in, free length: 150mm/5.91in, 2 springs in total. [Material] The double hook spring is made of high quality stainless steel, resistant to rust and corrosion, wear-resistant and heat-resistant, suitable for long-term use. [Function] The spring can be used in various applications such as production assembly, experimentation, research and development, maintenance, and more. It is widely applicable in electronics, household appliances, furniture, machinery, and other industries. [Package] 2pcs x Compression Spring, Type: Double Hook. The spring surface is uniform and smooth, polished to enhance surface finish. The spring offers strong load-bearing capacity. [Principle] The stainless steel spring can produce 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. Feature: Our tension springs have undergone strict and professional testing to ensure product quality. The springs offer good elasticity, high precision, and an attractive appearance. Stainless steel springs are polished after manufacturing, resulting in enhanced load-bearing strength. Our springs are suitable for everyday applications.
