Stainless steel tension springs engineered for reliable, heavy duty performance in industrial and hobby applications. Key benefits Durable construction: Made from stainless steel for long service life, corrosion resistance, and rust protection. Smooth, burr finish: Reduced risk of sharp edges for safer handling and cleaner assembly. Consistent performance: Uniform pulling force and strong hooks provide reliable tension and repeatable operation. Versatile fit: Precise dimensions ensure a secure fit across a wide range of assemblies. Specifications Wire diameter: 0.9 mm (0.035 in) Outer diameter: 8 mm (0.32 in) length: 40 mm (1.57 in) Ends: Loops at both ends for firm attachment points Performance and function Strong hooks and consistent elasticity allow these springs to absorb and release energy repeatedly without deformation. The precise size and uniform pull make them suitable for replacement and designs where predictable tension is required. The stainless steel material helps maintain performance in environments where moisture or exposure could cause corrosion. Typical applications and use scenarios or replacement in hand tools and latches where compact, reliable tension is needed. or tension springs in small engines and vehicle linkages, such as throttle or control mechanisms. Assembly and prototyping for electronics, toys, fixtures, and small machinery that require consistent pull force. Why choose these springs Clear, measurable specifications for easy selection and compatibility. Built for repeated use in commercial, research, and consumer projects. Simple installation with looped ends for secure attachment in a variety of mounting layouts. If you need a compact, corrosion resistant tension spring with dependable elasticity and precise dimensions, these stainless steel springs offer a practical solution for maintenance, repairs, and designs.
