Key principles.
Standard
Standard class. Most production threading.
Precision
Precision class. Tighter tolerance. Aerospace, instruments.
Lathe
Lathe single-point threading. Most precise. Slower.
Production
Die-cut threads on lathes. Faster than single-point.
Internal
Internal threads via tap. Standard for production.
Strongest
Cold-roll forms threads. Strongest, fastest, requires specific equipment.
