Material: 304 stainless steel for corrosion resistance and durability. Precise size: wire diameter 1.6 mm (0.063 in); outer diameter 20 mm (0.79 in); length 150 mm (5.91 in). This size combination provides a strong, secure fit for various applications. Performance and construction: ends feature strong hooks and loops for secure attachment points; uniform pulling force and elasticity deliver reliable resistance and resilience under tension. Wide application: suitable for electronics, tools, toys, construction, and machinery; also used in manufacturing, research, automotive, and aerospace. Why you need it: provides controlled tension and dependable in levers, lids, panels, and fasteners; durable in demanding environments and versatile across projects. Use scenarios: Electronics enclosure: used as a latch spring to ensure a cover or panel closes reliably after opening. Automotive or machinery: serves as a spring for levers or control panels, maintaining position after actuation. DIY and household projects: useful for cabinet doors, toy mechanisms, model builds, or any application requiring a robust tension . Installation notes: with an outer diameter of 20 mm, ensure adequate space and proper mounting orientation; verify hook/loop ends are compatible with mating components and load direction.
