10 x Stainless Steel Torsion Springs Wire Diameter 0.5 mm Inner Diameter 4 mm Arm Length 40 mm Angle 90° 5 Turns Right Rotation 0.5 x 4 x 40 mm

Specifications: 10 pieces torsion springs 0.5 x 4 x 40 mm, wire diameter: 0.5 mm, inner diameter: 4 mm, arm length: 40 mm, number of turns: 5. High strength and elasticity. Performance: arm clamping angle: 90°, maximum use angle: 60°, direction of rotation: straight, prevents plastic deformation due to angle limitation. Adjustable: The length of the torsion spring arm can be shortened according to your needs. Avoid exceeding the maximum angle to prevent the spring arm from resetting. Wide applications: spring surface polishing treatment, smooth and burr-free. Widely used in micromotors, medical instruments, precision gauges and other fields.
