Description
Hex bolt M20 x 40, modeled from published dimensions. Overall 34.6 x 30 x 52.5 mm. Key dimensions: thread diameter 20 mm; pitch 2.5 mm; length under head 40 mm; head across flats 30 mm; head height 12.5 mm. Modeled right-hand nominal 60-degree threads. Tolerance allowances, root radii and manufacturing runouts are simplified; use the stated nominal dimensions for layout. ISO 4017 head dimensions; the M10, M12 and M14 spanner sizes follow ISO rather than the older DIN dimensions. 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.
