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.
is an obsolete German standard for a 6 µm electroplated zinc coating with blue-bright chromate (type 2) . It offers mild corrosion protection, good appearance, and electrical conductivity. It has been replaced by ISO 2081 (Fe/Zn 6c). The full standard text is copyrighted and cannot be reproduced here, but the technical parameters above match its historical content.
The designation originates from German Industrial Standards (DIN - Deutsches Institut für Normung). While DIN standards cover a broad range of specifications, the "509E" prefix often refers to specific surface, structural, or fastening characteristics, particularly regarding specialized undercuts or retention mechanisms in manufacturing.
: The term "EXCLUSIVE" might imply a high level of quality, a specific application, or perhaps a proprietary specification used within certain industries.
Machinists often choose between DIN 509 Form E and Form F. The table below highlights the crucial differences that dictate their application: Form E (e.g., E0.6x0.2) Form F (e.g., F0.6x0.2) Ideal for components with one finished surface.
Finding a plater certified for is challenging. As of 2025, fewer than 20 job shops in North America and 40 in Europe hold the specific bath chemistry and quality system for the "exclusive" designation.
