(also known as a relief groove) used in mechanical engineering. It is a standardized feature machined into a shaft or bore to ensure that mating parts can sit flush against a shoulder or to provide clearance for grinding tools. Technical Breakdown

When a mating component—such as a bearing, washer, or gear—is pressed onto a shaft, it must sit entirely flush against the locating shoulder. If a radius or burr remains at the corner, the mating part will stall prematurely. The E0.6x0.2 groove completely clears out that corner space, guaranteeing perfect axial seating. din 509e06x02 exclusive

Standard DIN 509 uses letters like C (colorless), B (blue), or G (yellow/olive) for chromate conversion coatings. However, is not a standard post-treatment code in the public DIN 508-509 library. This is where the "exclusive" part comes into play. If a radius or burr remains at the

While the DIN 509 standard offers a broad table of options (radii ranging from 0.1 to 1.6 mm or more), the E0.6x0.2 combination serves a niche, sometimes considered "exclusive," purpose. The 0.6 mm radius (
