Designed with offset dual straight legs and a multi-coil body, this spring delivers stable torque output in complex installation spaces for reliable rotary return and linkage control.

Featuring integrated double positioning ears with a multi-coil body, this spring delivers stable torque output while providing secure installation positioning for high-cycle rotary return mechanisms.

Featuring an asymmetric design with a loop end for hook mounting and a long straight leg for positioning, it delivers reliable torque transmission and precise return action within limited installation space for various rotary linkage mechanisms.

Stores exceptionally high torsional energy within a compact footprint through its ultra-high-turn closely wound structure, delivering powerful and durably stable angular return force for precision rotational mechanisms.

Integrally combining a rectangular frame, torsion coil, and U-fork hook, the coil torque provides continuous clamping force for the elastic retention of banknotes, ID cards, and name badges.

Combining torsional spring force with a U-fork arm for positioning, the coil drives the U-fork end to clamp or actuate target components for precise elastic gripping and return action.

One end short leg for positioning and one end large rectangular frame arm for force transmission, purpose-built to deliver stable large-contact-area torque output and precise return for latch bolts and clutch mechanisms.

Integrally formed from a single wire into a twin-coil structure, delivering higher torque output than a single-coil spring within the same installation footprint — widely used in furniture hinges and door lock return systems.

One end loop for hook mounting and one end short leg for positional support, delivering stable torque in a compact multi-coil body for latch and consumer product open-close return functions.

The U-shaped arms on both ends snap directly into slots or plates, delivering precise and reliable return torque for latch, clamp, and pedal mechanisms.

With arms extending 180° in opposite directions, the arms and multi-coil energy storage deliver powerful, stable return torque for opening and closing mechanisms.

Featuring extra-long dual straight legs with small bent tips, delivering stable torque output for precise return of pedals, covers, and other heavy-load components.
