Material: 304 stainless steel. Precise size: wire diameter 2 mm (0.079 in), outer diameter 17 mm (0.67 in), length 70 mm (2.76 in). This dimensions set provides a secure fit and dependable performance across varied applications. Strength and elasticity: strong hooks and uniform pulling force support demanding tasks. End loops offer firm attachment points, while the spring's elasticity delivers reliable resistance and resilience under tension. Wide application range: suitable for manufacturing, research, automotive, and aerospace. Also widely used in electronics, tools, toys, construction, and machinery for both commercial and projects. Use scenarios: In electronics or small appliances, use to secure panels or lids with consistent tension and easy attachment. In automotive interior components, use for trim retention, latches, or covers that require reliable force. In DIY projects and machinery, use as a general tensioning or spring for model builds, tools, or mounting assemblies.
