Finding the right torsion spring for a repair or build project can be frustrating when off-the-shelf options don't match your exact torque or geometry requirements. Whether you're a mechanical engineer, hobbyist, or maintenance technician, having a reliable selection of right-hand torsion springs in precise dimensions saves time and eliminates guesswork.
Each pack contains 10 torsion springs wound from 0.4mm (approx. 0.016 in) hardened steel wire. Outer diameters range from 3mm to 6mm (approx. 0.118 in to 0.236 in) depending on the variant selected, with coil counts from 3 to 9 and leg angles of 60°, 90°, 120°, or 180°. The right-hand (clockwise) winding direction suits the majority of standard mechanical assemblies.
These torsion springs are well-suited for small appliance mechanisms, electronic enclosure latches, automotive trim clips, model engineering projects, and precision instrument assemblies where consistent return force and compact geometry are essential.
Consistent wire diameter across all variants for predictable spring rate and reliable torque output in compact assemblies.
Seven outer diameter sizes from 3mm to 6mm (0.118"–0.236") let you match the spring precisely to your housing or bore.
Clockwise coil direction suits the majority of standard mechanical pivot and hinge applications without modification.
Choose from 3 to 9 active coils to tune the spring rate and angular deflection range for your specific load requirement.
Leg angles of 60°, 90°, 120°, and 180° cover the most common torsion spring configurations used in DIY and industrial design.
Each order includes 10 identical springs, giving you spares for prototyping, batch repairs, or multi-unit builds without reordering.

Measure the bore or housing your spring will sit in, then select an OD slightly smaller to allow free rotation. For shaft-mounted springs, the inner diameter (OD minus twice the wire diameter) must be larger than your shaft. Available ODs range from 3mm to 6mm in this listing.
More coils increase the angular deflection range and reduce the spring rate (softer spring), while fewer coils produce a stiffer spring with less travel. Choose a higher coil count for applications needing a gentle, sustained return force, and a lower count for a firm, snappy action.
The leg angle is the angle between the two straight legs of the spring in its free (unloaded) state. Match this to the geometry of your assembly: 90° is the most common for hinges and latches, 180° suits inline or flat configurations, while 60° and 120° are used in specialized pivot mechanisms. Measure the angle between your mounting points to confirm.
These springs are made from hardened steel wire. For indoor or dry environments they perform reliably. For humid, wet, or outdoor applications, consider applying a light coating of oil or grease, or contact us to confirm if a coated variant is available for your size.
These are right-hand (clockwise) wound springs. When the spring is loaded in the tightening direction (clockwise when viewed from the front), the coils close and the spring stiffens. Using the wrong wind direction in a mechanism can cause the spring to unwind under load rather than store energy. Confirm your assembly requires a right-hand spring before ordering.
Yes. The compact 3–6mm OD range and fine 0.4mm wire make these springs well-suited for model engineering, RC mechanisms, electronic enclosure latches, small appliance hinges, and precision instrument assemblies where space is limited and consistent return force is needed.
Spring rate for torsion springs depends on wire diameter, coil diameter, number of active coils, and material modulus. If you need a specific torque value, contact us with your load and deflection requirements and we can help identify the closest matching variant or advise on a custom option.
