Torsion springs

Torsion springs can be found, just like compression or tension springs, in many products we daily use. Think about the good old mouse trap, garage door, or the lid of the letterbox. A torsion spring functions through rotating movements. In this way, a large force can be applied. Torsion springs are mostly built in or clamped in, and that is why this springs have protrusions on both sides.

Because of the multitude of possibilities and applications of a torsion spring, there are very many types and forms. We advise and calculate which type is the best for your application.


The torsion springs are made on our CNC controlled bending/winding machines, and, if necessary, manually finished. The springs can be made of a large assortment of spring steel. ATV Springs manufactures torsion springs with a wire thickness of 0.30 to 12 mm.

  • Class-DH spring steel to 2 mm

  • Chrome-Vanadium
  • Rust proof spring steel: RVS 302 , RVS 316
  • Phosphor bronce
  • Inconel X750

We also produce compression springs from square wire. Please contact us for information about all the options.
