Stainless steel tension springs designed for heavy duty use, with precise dimensions and a smooth, burr finish for safe, long lasting performance. Key benefits Durable construction: Made from stainless steel for strong wear resistance and long service life. Corrosion and rust protection: Material choice minimizes surface corrosion for consistent operation in most environments. Consistent performance: Uniform pulling force and strong end loops provide reliable elasticity and predictable response under tension. Safe and smooth finish: Burr surface reduces risk of catching or damage during installation and use. Exact fit: Precise wire and outer diameters ensure a secure fit in assemblies that require consistent spring dimensions. Specifications Material: stainless steel Wire diameter: 0.9 mm (0.035 in) Outer diameter: 7 mm (0.28 in) length: 45 mm (1.77 in) Ends: Closed loops on both ends for firm attachment Surface: Smooth, burr finish Typical applications and use scenarios Small machinery and equipment: worn tension springs in tool assemblies, latches, and mechanical linkages where exact sizing is required. Automotive and hobby projects: Use as or tension springs in throttle linkages, door mechanisms, or model assemblies that accept a 0.9 mm wire diameter spring. Prototyping and industrial fixtures: Ideal for jigs, fixtures, and test rigs in manufacturing or research that need consistent pull force and durable cyclic performance. Installation and compatibility notes Confirm required wire diameter, outer diameter, and length before installation to ensure proper fit and function. Attach loops to secure anchor points and avoid over stretching beyond the spring elastic limit to maintain performance. Suitable for commercial and projects across electronics, tools, toys, construction, and machinery when dimensions match application requirements. these tension springs when you need reliable, precisely sized components that deliver consistent tension, strong attachment points, and a smooth finish for safer installation and longer service life.
