In the world of engineering, there is a paradox: to make something strong and rigid, you must first allow for a little bit of space. is the international blueprint for that space. It defines the diameters of clearance holes for general-purpose bolts and screws, ensuring that when two parts are joined, they actually fit together. 1. The End of "Trial and Error"

Cosmetic surface damage. These are the only discontinuities that are virtually always accepted, provided they are not sharp (notch effect) and do not intersect a thread root. pn en 20273 1998

. This standard provides the necessary dimensions for clearance holes to ensure that bolts, screws, and other fasteners can pass through components without interference. Purpose and Technical Function In the world of engineering, there is a
