When a worn or undersized torsion spring causes your mechanism to bind, slip, or fail prematurely, finding the exact replacement is critical. These right-hand wound torsion springs are designed for engineers, technicians, and serious DIYers who need a dependable, dimensionally accurate spring without ordering custom tooling. Available in a pack of 10, they suit both prototyping and small-batch production runs.
Each spring is formed from 1.4mm diameter spring steel wire with outer diameters ranging from 7mm to 15mm (approximately 0.28" to 0.59"). Coil counts span 3 to 9 turns, and leg angles are available in 60°, 90°, 120°, and 180°, giving you precise control over torque output and deflection geometry. Select your combination using the variant options above.
Typical applications include door hinges and latch return mechanisms, small appliance lid assemblies, automotive interior clip-and-return systems, and precision instrument panel components where a compact right-hand torsion spring is required.
Consistent wire diameter across all variants ensures predictable spring rate and fatigue life in repetitive-cycle applications.
Nine outer diameter options (7, 7.5, 8, 8.5, 9, 10, 12, 14, 15mm) let you match the exact bore or housing diameter of your assembly.
Consistent right-hand coil orientation for applications requiring clockwise torque delivery when the spring is loaded from the front leg.
More coil options mean finer control over angular deflection and stored energy — choose fewer coils for stiffer response, more for greater travel.
Pre-formed leg angles eliminate field bending and reduce stress concentration at the leg root, extending service life.
Economical multi-pack quantity suits prototyping, maintenance stock, and small production runs without minimum order commitments.

Measure the bore or housing your spring sits in, then select an OD slightly smaller to allow free rotation. For mandrel-mounted springs, the inner diameter (ID = OD − 2 × wire diameter, approximately) must clear the mandrel with a small running clearance of 0.1–0.3mm. If you are unsure, contact us to confirm before ordering.
A right-hand wound torsion spring coils in a clockwise direction when viewed from the front (the end where the coil begins). When the front leg is deflected clockwise, the spring stores energy. This is the most common wind direction for standard door, latch, and hinge applications. If your mechanism requires counter-clockwise torque, you will need a left-hand wound spring instead.
More active coils reduce the spring rate (force per degree of deflection), allowing greater angular travel before reaching the load limit. Fewer coils produce a stiffer spring with higher torque per degree. For a given wire diameter and OD, doubling the coil count roughly halves the spring rate. Choose 3–4 coils for stiff, high-torque applications and 7–9 coils for softer, high-travel mechanisms.
These springs are manufactured from spring steel, which offers good mechanical properties but moderate corrosion resistance. For indoor or dry environments they perform reliably over extended service. For humid, wet, or chemically exposed environments, consider applying a light protective coating after installation, or contact us to enquire about alternative material options.
The leg angle is the angle between the two straight legs of the spring in its free (unloaded) state. Select the angle that matches your assembly's geometry: 90° is the most common for right-angle brackets and hinges; 180° suits parallel-leg configurations such as clip returns; 60° and 120° are used in compact or angled housings. Measure the angle between your mounting points to determine the correct choice.
Yes. Spring steel torsion springs of this type are suited to moderate-to-high cycle applications when operated within their rated deflection range. Avoid exceeding the maximum angular deflection for the selected coil count and OD, as over-deflection accelerates fatigue. For critical high-cycle industrial applications, contact us to discuss material grade and surface treatment options.
Each variant (OD × coil count × angle combination) is sold as a separate pack of 10 identical springs. To receive mixed sizes, add each variant to your cart individually. There is no minimum order quantity per variant beyond the pack of 10.
