When a worn or broken torsion spring brings your tools, hinges, or mechanical assemblies to a halt, finding the right replacement quickly matters. This torsion spring assortment is designed for DIY enthusiasts, maintenance technicians, and workshop professionals who need a dependable rotational-force solution across a wide range of applications.
Each torsion spring in this assortment is formed from 1.5mm wire diameter steel, with outer diameters ranging from 10mm to 18mm (approximately 0.39" to 0.71"). Available in six leg angles — 45°, 60°, 90°, 120°, 180°, and 270° — and coil counts from 1 to 5, these springs deliver consistent torque and return force suited to compact mechanical assemblies.
Typical use cases include tool trigger mechanisms requiring a torsion spring for tools maintenance, cabinet door hinges needing a DIY torsion spring replacement, and light-duty mechanical assemblies where a small torsion spring with precise leg angle is critical for correct function.
1.5mm Wire Diameter — Consistent wire gauge across all variants ensures uniform spring rate and predictable torque output for compact assemblies.
Wide OD Range: 10–18mm — Five outer diameter options (10, 12, 14, 16, 18mm) let you match the spring precisely to your housing or shaft diameter.
Six Leg Angles Available — Choose from 45°, 60°, 90°, 120°, 180°, or 270° to match the rotational geometry of your specific mechanism.
1 to 5 Coil Options — Select the coil count that delivers the spring rate and deflection range your application requires.
Broad Application Fit — Engineered for tools maintenance, DIY repairs, hinges, latches, and light mechanical assemblies where rotational return force is needed.
Sold Individually by Variant — Each listing covers one spring per unit; select your exact angle, OD, and coil count combination from the variant options above.

The leg angle refers to the angular position between the two legs of the torsion spring when it is in its free (unloaded) state. Measure the angle between the two mounting legs on your existing spring or the angle required by your mechanism's geometry. Common choices: 90° for right-angle hinges and latches, 180° for straight-leg return mechanisms, and 270° for applications requiring a large pre-load angle.
The outer diameter is the measurement across the outside of the coil body. When selecting a replacement spring, ensure the OD fits within your housing bore or surrounding structure. The inner diameter (ID) — which determines shaft fit — is derived from the OD minus twice the wire diameter (1.5mm × 2 = 3mm). For example, a 12mm OD spring has an approximate ID of 9mm.
More coils generally result in a lower spring rate (softer, more deflection per unit of torque) and greater angular travel before reaching the load limit. Fewer coils produce a stiffer spring with less angular travel. Match the coil count to the deflection range and torque requirement of your mechanism. If you are unsure, contact us to confirm the best option for your use case.
These torsion springs are made from steel. For indoor or dry-environment applications such as tool mechanisms and cabinet hinges, standard steel construction performs reliably. For outdoor or high-humidity environments, consider applying a light protective coating after installation. If you require a specific corrosion-resistant finish, contact us to confirm available options.
These springs are designed for light-to-medium duty applications including tools maintenance, DIY repairs, hinges, and latches. For heavy-load or outdoor applications with continuous moisture exposure, verify the spring rate and material finish match your load requirements. Contact us to confirm suitability before ordering for demanding environments.
To confirm compatibility, measure your existing spring's wire diameter (should be 1.5mm), outer diameter (10–18mm range), leg angle, and coil count. Match all four parameters to the variant options available. If your existing spring is worn or deformed, use the housing bore size to determine the correct OD and the mechanism geometry to determine the leg angle.
Each order is for one (1) individual torsion spring. Select your required combination of leg angle, outer diameter, and number of coils from the variant selectors above, then add the quantity you need to your cart.
