DIN 471 external circlip 20 mm
DIN 471 external circlip 20 mm, modeled from published dimensions. Overall 25 x 25.1 x 1.2 mm. Key dimensions: nominal shaft 20 mm; free diameter 18.5 mm; thickness 1.2 mm; crown radial width 2.6 mm; pliers hole diameter 2 mm; mating groove diameter 19 mm; mating groove width 1.3 mm; condition Free / uninstalled. Free-state diameter, thickness, crown width and pliers holes follow the cited table. The ring must deform for installation; the separate groove dimensions describe its mating feature. Ring outline, end-gap width and lug shape are representative; the source explicitly permits manufacturer-dependent outlines. No elastic or load-capacity simulation is assigned. Exact solid STEP geometry in millimeters, opens in any CAD system. Export to STL, OBJ, GLB and other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.
