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 against its limits; dw min sets the chamfer's face circle; mw min is checked at the corners.

Conventions
e Square: sharp at the modeled s (the middle of its band), one corner on +X.
« Corner chamfer on the bearing face only: a cone at B (range midpoint) meeting the face on (dw min + s) / 2. Not specified by the standard. « No countersink on either face.
¢ Bore: plain at D (simplified); ISO 68-1 basic internal thread over the full height (threaded), running out at both faces.
« Sharp edges, no markings. Values given only as a limit are modeled at that limit. Features the standard does not dimension are house conventions.
