Torsion Springs

A torsion spring is a spring in which the arms extend at an angle of about 90 to 180 degrees on both ends in a coil shape. It uses the force to return to the action of expanding or contracting the arm when it is installed in a part or product. Applications range from familiar products such as pruning shears, door knobs, and hanging parts for clothes hangers to home appliances. Since the material is often used outdoors, it is mainly made of stainless steel that does not rust. Since the spring force varies depending on the wire diameter and the number of coil turns, select the appropriate one depending on the parts and products used.
