[Specification] Wire diameter 2mm, outer diameter 18mm, free length 150mm, 2 springs included. [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] This spring is suitable for various applications such as assembly, experimentation, research and development, and maintenance. It can be widely used in electronics, household appliances, furniture, and machinery. [Package] 2 x Compression Spring, Type: Double Hook. The spring surface is uniform and polished to enhance 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 are manufactured under strict quality standards to ensure reliability. They offer good elasticity, high precision, and a clean appearance. Stainless steel springs are polished after production, enhancing durability and load-bearing performance. Suitable for general daily use.
