 * : If the lead angle is less than 5°, it is a self-locking gear. A typical example are the tuning pegs on a guitar or ukulele.
 * : At a worm gearing, clearance is the distance between the tooth tip of the worm and the tooth root of the worm wheel.
 * : Using ISO (International Organization for Standardization) guidelines, Module size is designated as the unit representing gear tooth-sizes. Module (m): m = 1 (p = 3.1416), m = 2 (p = 6.2832), m = 4 (p = 12.566). If you multiply Module by Pi, you can obtain Pitch (p). Pitch is the distance between corresponding points on adjacent teeth. If the module is changed, the lead angle also changes.
 * : The number of teeth in a worm is called the number of threads. Correspondingly, one speaks of single, double or multiple thread worms. In general, mainly single worms are produced, but in special cases the number of starts can be up to four (sometimes also more). If the number of teeth is changed, also changes.
 * : Only change the parameter, if sufficient knowledge of the gear geometry is available.
