Tension spring made from spring steel, engineered for reliable strength and consistent performance across a wide range of applications. Key benefits Durable strength: Manufactured from spring steel to provide dependable load-bearing capacity and long-term mechanical integrity. Fatigue-resistant: Designed to retain elasticity and functional performance through repeated cycles, reducing the need for frequent replacement. Clean, precise finish: Smooth, even surface without irregularities such as sand holes or black spots, offering a polished appearance and fewer stress concentrators. Easy fit and predictable behavior: Accurate dimensions help ensure consistent force and compatibility with assemblies that require reliable spring characteristics. Specifications Material: Spring steel Type: Tension (extension) spring Wire diameter: 2 mm Outer diameter: 10 mm Free length: 400 mm Performance and compatibility notes Use this spring where a reliable extension force and fatigue resistance are required. Its precise dimensions make it suitable for repairs or new builds where tolerances matter. Before installation, verify the wire diameter, outer diameter, and free length against your application to ensure proper fit and load behavior. Typical applications Mechanical and industrial assemblies: Return or tension components in jigs, fixtures, and small machinery. Automotive and equipment repair: Replacement extension spring for hoods, lids, or accessory linkages where a consistent pull force is required. Agricultural and gate hardware: Tension elements in gates, latches, and equipment that undergo frequent cycling. Simple selection guidance Match the spring’s wire diameter, outer diameter, and free length to your mounting points and required working force. If precise load curves are required for critical applications, test under expected conditions to confirm behavior. Reliable, fatigue-resistant spring steel construction with clean surface quality for consistent, long-lasting performance.
