Torsion metal springs are vital components found in a wide range of applications, from garage doors to industrial machinery. When these springs are wound or unwound, they exert a twisting force known as torque. Accurate measurement of torsion springs is critical to ensure proper fit, functioning, and safety in any application. In this article, we will explore how to measure torsion springs accurately with a step-by-step guide, including the necessary tools, techniques, and considerations.

Fundamentals of Torsion Springs

Torsion springs are helical in shape and made of tightly coiled wire or rod. When twisted, potential energy is stored in them. When the force is released, this energy causes the spring to unwind and exert torque. Torsion springs are characterized by several key parameters:

Wire Diameter: The thickness of the wire used to make the spring, measured in inches or millimeters.

Outer Diameter: The total diameter of the spring, including the wire thickness, measured in inches or millimeters.

Leg Length: The distance between the spring’s end and the first active coil, measured along the spring’s axis.
