helixhoek
Helixhoek, or helix angle, is a geometric property of a helix on a cylindrical surface. In engineering, it describes the steepness of a screw thread and the orientation of teeth on helical gears. The term is used in Dutch-language technical literature and is defined with context-specific meaning.
For screws and threaded fasteners, the helix angle at the pitch diameter is the angle between the
In helical gears, the helix angle β is the angle between the tooth trace and the gear axis,
Measurement and application: Helix angles are specified during design and verified with measurement tools; manufacturing tolerances
