Conventions
« End: ISO 4753 chamfered end (CH), end face at d1, chamfer at the angle limit. « Head: hexagon at the modeled s, one corner on +X; washer face (dw min + s) / 2, c high; top chamfer at B (house construction, ADR 0052 amendment 1).
« Thread (threaded level): ISO 68-1 basic profile, right hand. « Values given only as a limit are modeled at that limit. Features the standard does not dimension are house conventions.
