*General tolerance for JIS B 0408 metal pressed products: use Grade B (plate thickness≦6.0mm), Grade C (plate thickness>6.0mm). For R bend it will be Grade C.
*If a painting/coating is specified, the standard value for material conditions is used.

The allowable dimensional tolerances are applicable only for dimensions for between holes on the same face and end-faces/perpendicular-faces that are adjacent as a result of the bending.
The tolerances are not applicable for hole-to-hole or hole-to-end face dimensions on non-adjacent faces (across multiple bent sections).
