Our torsion springs are precision-made from high-grade spring steel with a durable black coating for corrosion resistance. Designed to deliver reliable rotational torque, they feature dual looped legs for secure attachment. We offer full customization: wire diameter, coil count, leg length, and material options (carbon steel, stainless steel). Suitable for automotive, industrial machinery, household appliances, and precision instruments. With strict quality control and factory-direct pricing, these springs ensure consistent elasticity, long service life, and cost-effectiveness for OEM and aftermarket projects.

Key Features:

High-Quality Materials: Made from high-strength spring steel/stainless steel with a wear-resistant black coating, our torsion springs deliver stable torque, excellent fatigue resistance, and long-lasting performance for industrial and automotive use.

Accurate Specifications: Precision-wound coils ensure uniform tension and consistent performance, with tight tolerances to meet exact engineering requirements.

Wide Customization: Available in custom wire diameters, free lengths, hook designs, and load capacities to fit your unique application needs.
