Description
Countersunk screw M8 x 20, modeled from published dimensions. Overall 16.4 x 16.4 x 20 mm. Key dimensions: thread diameter 8 mm; pitch 1.3 mm; length including head 20 mm; head actual diameter 16.4 mm; head reference height 5 mm; cone included angle degrees 90; socket across flats 5 mm; socket depth 2.9 mm. Modeled right-hand nominal 60-degree threads. Tolerance allowances, root radii and manufacturing runouts are simplified; use the stated nominal dimensions for layout. Overall screw length includes the countersunk head. Actual maximum head diameter is used; the rounded head rim is simplified to a short cylindrical band above a 90-degree cone. 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.
