When a flimsy spring causes a mechanism to fail mid-project, the frustration is real. Engineers, hobbyists, and repair technicians who need a reliable, corrosion-resistant torsion spring with exact angular and coil specifications will find this range indispensable. These right-hand wound torsion springs are engineered for consistent torque delivery across a wide range of angular deflections.
Each spring is manufactured from 0.35mm stainless steel wire with an outer diameter ranging from 2mm to 5mm (approx. 0.08 in to 0.20 in). Coil counts are available from 1 to 5 turns, and angular options span 45°, 60°, 90°, 120°, 180°, and 270°, giving you precise control over the spring's working angle and torque output.
Typical use cases include small appliance repair requiring a right-hand torsion spring replacement, precision instrument assembly where a compact stainless steel coil spring is needed, and DIY mechanical projects such as custom latches, hinges, or return mechanisms that demand a specific deflection angle torsion spring.
Corrosion-resistant wire construction maintains spring performance in humid or exposed environments without surface treatment.
Choose from 45°, 60°, 90°, 120°, 180°, or 270° deflection angles to match your mechanism's exact working range.
Consistent right-hand winding ensures predictable torque direction for standard mechanical assemblies and replacement applications.
OD options from 2mm to 5mm (0.08–0.20 in) allow precise fitment to shafts and housings across a broad range of applications.
Select 1 to 5 active coils to tune spring rate and angular travel for your specific load and deflection requirements.
Suitable for small appliances, precision instruments, custom latches, hinges, and return mechanisms requiring a compact torsion spring.

The outer diameter (OD) should be selected based on the shaft or housing bore it will fit around or inside. For a shaft-mounted spring, the OD should be slightly larger than the shaft diameter to allow free rotation. For a housing-mounted spring, the OD should be slightly smaller than the bore. Available ODs range from 2mm to 5mm in this listing.
The deflection angle is the angular travel the spring is designed to work through from its free (unloaded) position to its loaded position. Choose an angle that matches the range of motion in your mechanism — for example, a 90° spring suits a quarter-turn latch, while a 180° spring suits a half-turn return mechanism.
More coils generally result in a lower spring rate (softer spring) for the same wire diameter and OD, allowing greater angular travel at lower torque. Fewer coils produce a stiffer spring. Select based on the torque and deflection requirements of your application. If unsure, contact us to confirm before ordering.
Yes. These torsion springs are made from stainless steel wire, which provides good resistance to rust and corrosion in typical indoor and mildly humid environments. For highly aggressive chemical or saltwater environments, please contact us to confirm suitability.
Right-hand winding means the coils wind clockwise when viewed from the end of the spring. This determines the direction in which the spring tightens or loosens under load. Most standard mechanisms use right-hand springs, but if your application requires a left-hand spring, please contact us before purchasing.
Yes, provided you match the wire diameter (0.35mm), outer diameter, coil count, deflection angle, and wind direction of the original spring. Measure the original spring carefully or refer to its part number before selecting your variant. If you need help identifying the correct replacement, contact us with your measurements.
A torsion spring stores energy by twisting around its axis and exerts a rotational (torque) force, making it ideal for hinges, latches, and return mechanisms. A tension spring stretches along its axis, and a compression spring compresses along its axis. Choose a torsion spring when your mechanism requires angular or rotational force.
