Conventions
¢ Boss: a straight cone from d2 at the bearing face to d3 at m, flat on top.
« Wing outline: lobes of r1 touching e/2 and h; outer flanks tangent from the boss's foot, inner flanks from the top of the boss with r3 at the flat. Not specified by the standard.
+ Wing faces: planes, g2 at the bearing face to g1 at h. Plan-view blends r4 at the boss, illustrative. Not specified by the standard.
« Wing edges sharp (r2: 'rounded', no value at this size; pending the owner).
« Bore: plain at D through the boss (simplified); ISO 68-1 basic internal thread over the full boss height (threaded). No countersink.
« No markings. Features the standard does not dimension are house conventions.
