Frequently Asked Questions
Q: What is a spiral flat wire coil torsion spring used for?
A: A spiral flat wire coil torsion spring (also called a scroll spring or clock spring) is used in mechanisms that require constant rotational torque across multiple angles — such as bench drills, clock movements, retractable cord reels, counterbalance mechanisms, and motor assemblies. The spring stores and releases energy as it winds and unwinds.
Q: What material is this torsion spring made from?
A: This spring is made from 60Si2Mn high-quality spring steel, a silicon-manganese alloy known for its excellent elasticity, high tensile strength, and strong resistance to fatigue — making it well-suited for continuous, long-term mechanical use.
Q: What wire thickness options are available?
A: This listing covers a wire thickness range of 0.7mm to 1.5mm. Please refer to the product variant selector to choose the exact thickness that matches your mechanical specification. If you are unsure, please measure your existing spring or consult your equipment's documentation before ordering.
