In mechanical engineering, a helix angle is the angle between any helix and an axial line on its right, circular cylinder or cone.[1] Common applications are screws, helical gears, and worm gears.
The helix angle references the axis of the cylinder, distinguishing it from the lead angle, which references a line perpendicular to the axis. Naturally, the helix angle is the geometric complement of the lead angle. The helix angle is measured in degrees.
