) provides a generous enough curve to significantly reduce stress concentration factors (SCF) compared to smaller radii (like 0.2 or 0.4 mm), while still being small enough to fit within limited assembly spaces.

Because this is a thin, high-performance code, you will not find it on ship anchors or bridge girders. Instead, look for it in these engineered niches:

(shoulder) does not require high precision or is not subjected to high fatigue loads.

The alphanumeric designation "E 0.6 x 0.2" acts as a shorthand for specific geometric requirements: ) provides a generous enough curve to significantly

If you're interested in learning more about this standard, I recommend:

: The 0.2mm depth is designed for "exclusive" fitment. It ensures that when you slide a bearing or a gear onto a shaft, it sits perfectly flush against the shoulder. Without that tiny 0.2mm of breathing room, the tiny leftover "fillet" from the machining tool would prevent a perfect 90-degree fit, leading to vibration and eventual machine failure. (shoulder) does not require high precision or is

Specifies an undercut for workpieces that require only one perpendicular bearing surface (the vertical shoulder face). Form E plunges diagonally or axially, cutting slightly into both planes but prioritizing the perpendicular face. 0.6: The precise corner radius ( ) of the undercut groove, measured in millimeters. 0.2: The plunge depth (
