Durable stainless steel tension springs engineered for reliable performance in commercial and projects. Precise sizing, strong hooks, and smooth, burr surfaces make these springs easy to install and long lasting in a wide range of applications. Key benefits Long service life: stainless steel construction resists corrosion and rust, reducing replacement frequency. Consistent performance: Uniform pulling force and strong hooks provide predictable tension and secure connections. Safe handling: Smooth, burr finish minimizes risk of cuts and snagging during installation and use. Versatile fit: Compact dimensions work well in tight assemblies while delivering dependable strength. Specifications Material: Stainless steel Wire diameter: 0.5 mm (0.02 inch) Outer diameter: 6 mm (0.24 inch) Length: 80 mm (3.15 inch) End type: Loops at both ends for firm attachment Typical applications Electronics and tools: springs for switches, levers, and small actuators where precise tension is required. Automotive and machinery: Cable , latch mechanisms, and lightduty assemblies that demand corrosionresistant components. Toys, models, and research equipment: Durable tension elements for repeated movement and controlled elasticity. Practical use scenarios Replacing a worn spring on a hand tool: Measure the original spring against these dimensions for an exact fit, install the looped ends on existing hooks, and restore consistent closing force. Restoring a model aircraft control surface: Use the springs to provide reliable pullback and resilience in a compact, corrosionresistant package. Improving a prototype or lab fixture: Install matching springs on parallel linkages to maintain even tension and predictable behavior during testing. Why choose these springs Exact, documented dimensions make selection straightforward and reduce trial and error. Robust hooks and uniform elasticity deliver dependable operation in repeated cycles. Smooth finish and corrosion resistance improve safety and longevity without adding complexity. If you need compact, heavyduty tension springs with predictable performance and corrosion resistance, these springs offer a practical solution for a broad range of industrial and hobby applications.
