[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 has a uniform and smooth surface with a polished finish to enhance surface quality. It offers strong load-bearing capacity. [Principle] The stainless steel spring can undergo significant elastic deformation under load, converting mechanical work or kinetic 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 an attractive appearance. The springs are polished after production, enhancing durability and load capacity. This spring is designed to meet everyday application needs.
