Material and build Made from high-quality, corrosion- and rust-resistant metal for long service life. Wear-resistant and high-temperature tolerant to maintain shape and function under stress. Key functions and features Double-hook ends for secure attachment to other parts; designed as a tension (extension) spring. When stretched, the spring generates reliable rebound force and strong tensile resistance. Uniform coil spacing and consistent force output for predictable performance. Performance advantages Excellent mechanical strength and heat resistance reduce risk of deformation and loss of function. Resistant to rust and corrosion, minimizing maintenance and replacement frequency. Stable, even tension and spacing ensure smooth operation in repetitive or load-bearing uses. Compatibility and typical applications Suitable for production assembly, laboratory experiments, research and development, and maintenance tasks. Widely applicable across electronics, household appliances, furniture, and machinery. Practical use scenarios Assembly line: secure and tension components during automated production or final assembly. R&D and testing: provide consistent, repeatable tension for prototype testing or experimental rigs. Appliance repair and maintenance: replace worn springs in small appliances, furniture mechanisms, or machine parts to restore reliable operation. Why choose this spring Durable material and construction reduce downtime and replacement costs. Versatile design with double hooks and consistent force makes it a practical choice for many industries and repair needs. Reliable performance in high-temperature or wear-prone environments ensures long-term functionality.
