In the cold, sterile light of the Quality Control lab, Marco stared at the blueprint until the lines blurred. The part on his desk—a high-tensile steel drive shaft—was failing every stress test. It was a masterpiece of machining, except for one fatal flaw: the threads met the shoulder at a sharp, jagged angle. "Stress concentration," he muttered, rubbing his eyes.

Does your thread require a stress relief groove? (High vibration? Yes → Use ISO 4755).
Is the mating part a blind tapped hole? (Yes → You must specify the a dimension to prove clearance).
Are you using fine pitch threads (M10x1.25 instead of M10x1.5)? (ISO 4755 primarily covers coarse pitch; consult the full standard for fine pitch adjustments).

Pro Tip: Always use the ISO 4755 undercut for aerospace and automotive components to avoid notch effects and fatigue failure. tabella gola uni iso 4755
