When a cabinet door won't stay closed, a tool-box lid droops, or a small mechanism loses its snap, the culprit is almost always a worn or mismatched torsion spring. Engineers, repair technicians, and hands-on DIYers who need an exact replacement — or a reliable spare — know how frustrating it is to source the right wire diameter, coil count, and leg angle all at once. This assortment solves that problem in a single order.
Each spring in this listing is wound from 0.6 mm carbon-steel wire. Outer diameters span 3 mm to 8 mm (approximately 0.12 in to 0.31 in), and coil body lengths are available in 3-coil, 6-coil, and 9-coil configurations (approximately 1.8 mm, 3.6 mm, and 5.4 mm body length respectively). Leg angles are offered at 60°, 90°, 120°, and 180°, and each size is available in both left-hand (LH) and right-hand (RH) wind to match the rotation direction of your application.
Typical use cases include replacing torsion springs in cabinet hinges and door-return mechanisms, restoring tension in small appliance lids and tool-box latches, and providing precise rotational force in jigs, fixtures, and light-duty automation assemblies — all scenarios where a correctly specified torsion spring with the right leg angle and wind direction is essential for reliable, repeatable performance.
Consistent wire diameter across the entire range ensures predictable spring rate and reliable torque output in every variant.
Outer diameters from 3 mm to 8 mm (≈ 0.12–0.31 in) combined with 3-, 6-, and 9-coil body lengths give you a broad selection to match your exact bore and travel requirements.
Pre-formed leg angles eliminate bending and reduce the risk of fatigue cracking at the leg root, keeping the spring geometry accurate from the first cycle.
Both winding directions are stocked so you can match the rotation of your mechanism without improvising or reversing the spring orientation.
Springs carry a light protective surface treatment suitable for indoor mechanical applications, helping maintain appearance and function over repeated cycles.
Each variant is sold individually, so you can order exactly the quantity you need — one replacement or a small stock of spares — without committing to a bulk pack.

Measure the mandrel or shaft the spring will sit on, then select an outer diameter that gives a small clearance — typically 0.2–0.5 mm larger than the shaft. If the spring wraps around a post, measure the post and choose an inner diameter (outer diameter minus twice the wire diameter) that fits snugly without binding.
Wind direction determines which way the spring tightens under load. A left-hand (LH) spring coils counter-clockwise when viewed from the leg end; a right-hand (RH) spring coils clockwise. To identify which you need, note the direction your mechanism rotates when it loads the spring — choose the wind direction that tightens (not unwinds) the coils under that rotation.
The leg angle is the angle between the two straight legs of the spring when it is in its free (unloaded) state. Measure the angle between the mounting points in your assembly when the mechanism is at rest, then select the matching angle. Common choices: 90° for right-angle brackets, 180° for inline return mechanisms, 60° or 120° for cam-style hinges.
The springs are wound from carbon steel wire and are designed for light-to-medium duty applications such as cabinet hinges, tool-box latches, and small appliance lids. Exact cycle life depends on the deflection angle and load applied. For heavy-duty or high-cycle industrial applications, consult the spring rate data for your chosen variant and verify it meets your fatigue requirements.
The light protective surface treatment provides basic corrosion resistance suitable for dry indoor use. For outdoor, high-humidity, or washdown environments, additional protection such as a corrosion-inhibiting grease or a stainless-steel alternative is recommended to maintain long-term performance.
Count the number of full 360° turns in the coil body — this is the coil count. A 3-coil spring has a body length of approximately 3 × wire diameter × π (roughly 1.8 mm for 0.6 mm wire); a 6-coil spring is approximately 3.6 mm; a 9-coil spring is approximately 5.4 mm. Always verify against your assembly's available axial space before ordering.
No — substituting the wrong wind direction will cause the spring to unwind under load rather than store energy, resulting in loss of function and potential damage to the assembly. Always match the wind direction to your mechanism's rotation.
