If a screw does not conform to ISO 4755 design rules (e.g., the groove is too shallow or the angle is wrong), the screw will likely fail during installation. tabella gola uni iso 4755

The tabella (table) in UNI ISO 4755 is organized by and pitch (p) . Below is a representative excerpt for coarse thread series (the full table extends up to M39 and includes fine threads). He pulled a worn, oil-stained manual from his

The table defines three main types of thread run-outs/undercuts, labeled (or sometimes short, normal, long). However, the most common gola reference for general mechanical design is the undercut for external threads (e.g., for bolts screwed up to a shoulder).

The UNI ISO 4755 standard is crucial for several reasons:

If a supplier says "conforms to DIN 76-1," they also conform to UNI ISO 4755 for 95% of metric sizes. However, always verify the specific a dimension if you have a blind hole with a specific depth.
