DIN 6797 features a deeper, more aggressive tooth profile than DIN 6798, providing stronger mechanical anti-loosening engagement — widely specified in electrical, automotive, and high-vibration applications. Form A (external toothed) features teeth on the outer diameter for maximum anti-loosening torque. Form J (internal toothed) features teeth on the inner diameter, preserving the outer substrate surface.
