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.
