Modeled value: nominal, else the midpoint of min-max. s / =: only that limit is given. * amber: one source (LO). c: a source value was corrected. Level - independent sources. e follows from s and is checked = e min; dw min sets the chamfer's face circle and the collar; mw min is checked at mid -flat.

Conventions
e Hexagon: regular at the modeled s (the middle of its band), one corner on +X, sharp edges.
« Corner chamfer on both hexagon faces: a cone at B (range midpoint) meeting the face on (dw min + s) / 2. Not specified by the standard.
« Countersink on the bearing face at da and 8, both at their range midpoints.
¢ Collar dw min across from m to h, wall and lip t = (dw min - D) / 4, top edge rounded at t; the nylon insert its own solid from m to h - t. Not specified by the standard.
« Bore: plain at D (simplified); ISO 68-1 basic internal thread through m, insert bore at D1 (threaded).
« No washer face, no markings. Values given only as a limit are modeled at that limit. Features the standard does not dimension are house conventions.
