65Mn Steel Right-Hand Torsion Springs — Precision-Wound for Reliable Torque in DIY, Mechanical & Industrial Applications
When a spring loses its tension or snaps mid-project, the whole assembly fails — and finding a replacement with the exact coil count, outer diameter, and rotation angle you need can feel impossible. These right-hand wound torsion springs are engineered to precise tolerances so you can restore function fast, whether you're repairing a tool, building a mechanism, or prototyping a new design.
Each spring is cold-wound from 65Mn spring steel wire (1 mm diameter, ±0.02 mm tolerance) and heat-treated to HRC 42–48 hardness. Outer diameters range from 5 mm (0.20 in) to 12 mm (0.47 in), with 3 to 9 active coils and a fixed leg length of 30 mm (1.18 in, customizable on request). Four rotation angles are available — 60°, 90°, 120°, and 180° — to match your specific torque requirement. Torque output typically ranges from 0.05 to 0.3 N·m depending on the selected configuration.
These right-hand torsion springs are widely used in tool repair, toy manufacturing, woodworking jigs, electronic device hinges, automotive interior mechanisms, and general DIY projects. Each pack contains 10 springs of the same specification. If you need left-hand wound springs or a custom leg length, please contact us before ordering.
🔧 Tool & Appliance Repair Technicians
Replace worn or broken torsion springs in hand tools, power tool triggers, cabinet hinges, and small appliances with a spring that matches the original specification.
🎭 Toy Makers & Prototype Builders
Integrate compact right-hand torsion springs into toy mechanisms, robotic joints, and prototype assemblies where consistent return force and long cycle life are critical.
🧰 DIY Enthusiasts & Woodworkers
Use these springs in woodworking jigs, door latches, flip-top boxes, and custom hardware projects that need a reliable spring-return action.
🏭 Industrial & Automotive Assemblers
Suitable for automotive interior clips, electronic device hinges, and light industrial mechanisms where a compact, right-wound torsion spring is specified.
What is the difference between right-hand and left-hand wound torsion springs?
A right-hand (clockwise) wound spring tightens when rotated clockwise and is the most common winding direction. A left-hand wound spring tightens when rotated counter-clockwise. The correct winding direction depends on how the spring is loaded in your mechanism. If you need left-hand wound springs, please contact us before ordering.
How do I choose the right coil count and outer diameter?
More coils generally produce a softer spring rate (lower torque per degree of rotation), while fewer coils produce a stiffer rate. A larger outer diameter also affects the spring rate. If you know the required torque and rotation angle, select the combination that falls within the 0.05–0.3 N·m range. Contact us if you need help selecting the right variant.
Can I shorten the leg length?
Yes. The standard leg length is 30 mm. You can trim the legs shorter using pliers or wire cutters as needed. If you need a specific custom leg length from the factory, please contact us with your requirements before placing an order.
What rotation angles are available?
Four angles are available: 60°, 90°, 120°, and 180°. Select the angle that matches the travel range of your mechanism from the variant options above.
How many springs are included per order?
Each listing includes 10 torsion springs of the same specification (same wire diameter, OD, coil count, and angle). Select your preferred Wire dia × Outer dia, Number of coils, and Angle combination before adding to cart.
What is the expected service life of these springs?
These springs are tested to ≥50,000 load cycles under standard conditions. Actual service life depends on the applied torque, rotation angle, and operating environment. Avoid exceeding the rated torque range to maximize longevity.
Are custom sizes available?
Yes. We can produce torsion springs in custom outer diameters, wire diameters, coil counts, leg lengths, and winding directions. Contact us with your specifications and quantity requirements for a custom quote.
