helical
Wound like springs
Helical means having the form of a helix—a three-dimensional spiral like a corkscrew or spiral staircase.
DNA has a helical structure, specifically a double helix.
Springs, drill bits, and certain staircases are helical.
The word appears most often in technical contexts: helical gears, helical antenna, helical motion.
