[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, Double Hook type. The spring surface is uniform and polished to enhance finish. The spring offers strong load-bearing capacity. [Principle] The stainless steel spring can undergo significant elastic deformation under load, converting mechanical energy into elastic potential energy. The tension spring is a helical spring designed to bear axial tension. Feature: Our tension springs are manufactured using strict and professional processes to ensure quality. They offer excellent elasticity, high precision, and a clean appearance. Stainless steel springs are polished after production, enhancing durability and load capacity. Suitable for general daily use.
