Decoding the Groove: The Essential Guide to the Tabella Gola UNI ISO 4755

In the world of mechanical fastening and threaded connections, precision is not just a metric; it is a safety requirement. When dealing with hexagon head bolts and screws, one of the most overlooked yet critical geometric features is the gola (often translated as the "undercut" or "fillet groove").

• Tapping Screws (Thread-forming and thread-cutting): Screws that create their own thread in the material.
• Metal Drive Screws: Screws driven in with a hammer.

• Thread Size (d): The nominal diameter of the bolt.
• Groove Diameter (d₁): The reduced diameter at the bottom of the undercut. This must be smaller than the minor diameter of the thread to ensure the groove provides real relief.
• Groove Width (a): The axial length of the undercut (how long the groove is).
• Radius (r): The transition fillet radius at the corners of the groove. A larger radius distributes stress better.

In conclusione, la tabella gola UNI ISO 4755 è uno strumento essenziale per la valutazione della gola delle ruote dentate. La sua adozione garantisce la qualità e la precisione dei prodotti, favorisce la standardizzazione e riduce gli errori. La tabella gola UNI ISO 4755 trova applicazione in diversi settori industriali e rappresenta un riferimento importante per i produttori di ruote dentate e ingranaggi. tabella gola uni iso 4755
