Torsion Spring

Wide Variety of Standard & Custom Torsion Springs

Torsion springs are helical springs that apply a rotary force when connected to other components. As these components rotate around the center of the spring, the torsion spring exerts a force to return them to their initial position. Unlike torsional stress, torsion springs endure bending stress and can store and release angular energy. They can statically hold a mechanism in place by deflecting the legs along the center-line axis of its body. HSI offers regular custom torsion springs as well as heavy-duty torsion springs to meet diverse design requirements.


The following are the specifications of torsion springs:

Length of Legsup to 24 inup to 609.6 mm
Wire Size0.004 to 1 in0.1 to 25.4 mm
Direction of WindingRight HandLeft Hand
MaterialBeryllium CopperMusic Wire
InconelChrome Silicon
Chromium VanadiumPhosphor Bronze
Stainless Steel 302Stainless Steel 304

Here are some of the parameters of torsion springs:

  • Outer Diameter: Specified for fitting into a circular hole or outer housing clearance issues.
  • Inner Diameter: Specify if the spring needs to slip over a mandrel.
  • Spring Length: Length of the spring coil.
  • Wire Diameter: Diameter of the spring wire.

Performance Factors:

  • Spring Rate: Angular return torque provided per unit of angular displacement.
  • Maximum Deflection: Maximum-rated angular deflection before damage.
  • Wind Specifications: Right hand, left hand, or double torsion.


Helical torsion springs designed for rotary actuation provide angular return force. Offered in various leg configurations for versatile attachment, leg specifications include leg end style, leg angle, and equal leg length.

Leading Leg End Styles

Helical torsion springs that are parallel or straight on the same side have 0° leg angle, and their angle increases in the direction of unwinding. Some of the leading leg-end styles include the following:

  • Straight Torsion
  • Straight Offset
  • Hinged
  • Short Hook Ends

Torsion springs can be hooked, bent, twisted, and looped to meet application requirements, available in a choice of 360°, 300°, 270°, 210°, 180°, 120°, 90°, and free leg positions.


Benefits of Torsion Springs:

Some of the major benefits of these springs are as follows:

  • Durable
  • Easy to adjust
  • Relatively small
  • Great automatic leveling


These types of springs are commonly used in:

  • Clothes pins
  • Clipboards
  • Swing-down tailgates
  • Garage doors
  • Hinges
  • Counterbalances
  • Lever return applications
