The standard (equivalent to ISO 4755:1983 ) specifies the required form and dimensions for thread undercuts (Italian: gole di scarico ) on externally threaded fasteners like bolts and screws. These undercuts are used to provide clearance for a mating part (such as a plug or sealing element) to sit flush against a shoulder when the thread cannot be run all the way to the end.

As technology continues to evolve, so too will the standards that govern its application. The UNI ISO 4755 standard is subject to periodic review and update to reflect advancements in technology, materials, and best practices. Stakeholders, including manufacturers, engineers, and regulatory bodies, must remain engaged with these developments to ensure continued compliance and to leverage new opportunities for innovation and growth. tabella gola uni iso 4755

Marco recalibrated the lathe. He followed the coordinates for a 1.5mm pitch: a depth of 0.5mm, a radius of 0.6mm. As the carbide tip bit into the steel, a perfect, smooth radius formed—a "Type A" undercut, exactly as the ISO standard demanded.
, ensuring no interference from incomplete "run-out" threads. for common thread sizes like M6 or M10?
Often referred to as the (Undercut Table), this standard specifies the dimensions for thread run-outs and undercuts for ISO metric screw threads (M profile).
