When a mechanism fails mid-project — a cabinet hinge loses its snap, a tool latch won't hold, or a small assembly loses its return force — the culprit is almost always a worn or incorrectly sized torsion spring. DIY enthusiasts, repair technicians, and mechanical hobbyists need a reliable assortment on hand to match the right spring to the right job without waiting on a single-size order.
This torsion spring assortment covers three distinct size profiles: 8.3 × 12.6 mm (outer diameter × free length), 0.5 × 6 mm × 2.5 mm (wire diameter × outer diameter × leg length), and 0.5 × 6 mm × 1.6 mm — giving you a practical range from compact precision applications to slightly larger mechanical assemblies. Wire diameters typically range from 0.5 mm to 0.8 mm (~0.020–0.031 in), with outer diameters spanning approximately 6–13 mm (~0.24–0.51 in).
Typical use cases include replacing torsion springs in door hinges and cabinet latches, restoring return tension in hand tools and clamps, and sourcing replacement springs for small appliances, toys, and electronic enclosures — all scenarios where having the correct size immediately on hand saves time and avoids project delays.
Covers 8.3 × 12.6 mm, 0.5 × 6 mm × 2.5 mm, and 0.5 × 6 mm × 1.6 mm — three configurations to match a wide range of mechanical applications in a single order.
Engineered for consistent torsional resistance, these springs deliver reliable return force in repetitive-cycle applications such as latches, hinges, and tool mechanisms.
Wire diameters of approximately 0.5 mm ensure accurate torque characteristics and consistent coil geometry, reducing the risk of premature fatigue or deformation under load.
Available in packs of 2, 5, 10, 25, 50, 100, and 200 pieces — order just what you need for a single repair or stock up for ongoing maintenance and production runs.
Suitable for cabinet hardware, door hinges, hand tools, small appliances, electronic enclosures, and hobby/maker projects requiring controlled rotational return force.
No cutting or bending required. Each spring arrives formed to specification with defined leg angles, ready to install directly into your assembly or repair application.

Measure the inner diameter of the bore or shaft the spring will sit on, the required leg length to engage your mechanism, and the wire diameter needed to achieve the desired torque. Compare these measurements against the three size profiles listed in the variants: 8.3 × 12.6 mm, 0.5 × 6 mm × 2.5 mm, and 0.5 × 6 mm × 1.6 mm. When in doubt, order a small quantity of two sizes to test fit before committing to a larger pack.
"High tension" indicates that the spring is wound to deliver a stronger return force relative to its physical size. This makes it suitable for applications where the mechanism must snap back firmly — such as latches, spring-loaded hinges, or tool return mechanisms — rather than applications requiring only light resistance.
The corrosion resistance depends on the material and finish of the specific variant. For outdoor or high-humidity environments, we recommend confirming the material specification via the variant details or contacting us before ordering. If corrosion resistance is critical, look for variants with a zinc or phosphate coating, or consider stainless steel options.
Yes. The 8.3 × 12.6 mm size is well-suited for cabinet hinges and small door hardware applications. Verify that the inner diameter of the spring clears the hinge pin and that the leg length is sufficient to engage the hinge body. The 0.5 × 6 mm variants are better suited for lighter-duty hardware such as small latches and snap closures.
For a single repair, a pack of 2 or 5 is typically sufficient and allows for a spare. For ongoing maintenance, workshop stock, or small production runs, packs of 25–100 offer better per-unit value. If you are stocking for a larger assembly operation, the 200-piece pack provides the lowest cost per spring.
Both variants share the same 0.5 mm wire diameter and 6 mm outer diameter, but differ in leg length: 2.5 mm vs. 1.6 mm. The leg length determines how far the spring's arm extends to engage the surrounding mechanism. Choose 2.5 mm for applications with a deeper engagement groove or longer lever arm, and 1.6 mm for tighter assemblies where space is limited.
Yes, all dimensions are specified in metric units (mm), making them directly compatible with standard metric hardware and assemblies. The outer diameters of 6 mm and 12.6 mm align with common metric shaft and bore sizes used in European and Asian-standard mechanical components.
