Return Tension Spring – Heavy Duty (131027R1)

A torsion spring is a mechanical coil spring designed to store and release rotational energy by twisting. It features coiled metal wire with extended legs on both ends, allowing it to apply torque when rotated. This type of spring is widely used in industrial equipment, mechanical assemblies, and automotive components where rotational force and return motion are required. It is typically made of high-carbon steel for durability and long service life.
