[Specification] Wire diameter 2mm, outer diameter 18mm, free length: 150mm, 2 springs in total. [Material] The double hook spring is made of high quality stainless steel, resistant to rust, corrosion, wear, and high temperatures, ensuring long-term use. [Function] The spring can be used in various applications such as production assembly, experimentation, research and development, and maintenance. It is widely applicable in electronics, household appliances, furniture, and machinery. [Package] 2 x Compression Spring, Type: Double Hook. The spring surface is uniform and polished to enhance surface finish. The spring has 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 that bears axial tension. Feature: Our tension springs have undergone strict and professional quality control to ensure reliability. The springs offer good elasticity, high precision, and a clean appearance. Stainless steel springs are polished after manufacturing, resulting in improved surface quality and strong load-bearing performance. Suitable for general daily use.
