: Because the undercut diameter is slightly smaller than the thread's minor diameter, the nut can now spin all the way down until it sits perfectly flush against the shoulder.

: The width of the relief is typically about three times the thread pitch ( din 76a pdf

DIN 76-1 (Form A) specifies dimensions for thread undercuts and run-outs on external metric threads to allow components to seat flush against a shoulder. The standard defines specific undercut diameters, widths, and radii based on the thread pitch to ensure proper assembly for standard requirements. The official technical documentation can be acquired through DIN Media or Beuth Verlag. : Because the undercut diameter is slightly smaller

: Specifically used for external threads (bolts/screws) where a "normal" undercut depth and width are required. Dimensions defined : : The diameter of the undercut (the "groove" diameter). : The width of the undercut. The official technical documentation can be acquired through
