Found in clothespins, spring clamps, and mousetraps, torsion springs wrap around a shaft or rod to maintain pressure on objects as they rotate.
Torsion springs should be used in the direction in which the coils are wound. Left-hand wound springs wind clockwise toward you.Right-hand wound springs wind counterclockwise toward you.
Deflection angle represents the angle between the legs as well as the maximum spring rotation. All springs rotate until their legs are parallel. For example, a spring with a 90° deflection angle will rotate a maximum of 90°. Maximum torque is the torque required to rotate the spring legs to the parallel position.
Rotating a torsion spring tightens the spring around a shaft and increases the spring length. Using a shaft with a larger diameter than the values listed for maximum shaft diameter will interfere with the spring’s motion.

Made of stainless steel, these springs are more corrosion resistant than steel springs. They're also easier to rotate than steel springs. Found in clothespins, spring clamps, and mousetraps, torsion springs wrap around a shaft or rod to maintain pressure on objects as they rotate.
Torsion springs should be used in the direction in which the coils are wound. Left-hand wound springs wind clockwise toward you. Right-hand wound springs wind counterclockwise toward you.
Deflection angle represents the angle between the legs as well as the maximum spring rotation. All springs rotate until their legs are parallel. For example, a spring with a 90° deflection angle will rotate a maximum of 90°. Maximum torque is the torque required to rotate the spring legs to the parallel position.
Rotating a torsion spring tightens the spring around a shaft and increases the spring length. Using a shaft with a larger diameter than the values listed for maximum shaft diameter will interfere with the spring’s motion.

Whatever the size, we'll get the spring you need. Send us a description, drawing, or sample of the torsion spring you require.
Deflection angle represents the angle between the legs as well as the maximum spring rotation. All springs rotate until their legs are parallel. For example, a spring with a 90° deflection angle will rotate a maximum of 90°. Maximum torque is the torque required to rotate the spring legs to the parallel position.
Torsion springs should be used in the direction in which the coils are wound. Left-hand wound springs wind clockwise toward you. Right-hand wound springs wind counterclockwise toward you.
Zinc-plated springs have mild corrosion resistance.
Stainless steel springs have good corrosion resistance. They’re generally easier to rotate than steel springs.
To Order: Select a deflection angle, and then please specify the following:
1) Wind direction: right hand or left hand.
2) Material: music-wire steel, stainless steel, or other material.
3) Finish: plain or zinc plated.
4) Dimensions: OD, wire diameter, leg length, and number of coils.
