M6X1.0 JIS 4-Mark Hex - Steel JIS B-1180
4-Mark (4.6) bolts were used in older OEM vehicles, but only for light-duty, non-structural parts, not for high-performance or structural applications. Sufficient for assemblies that don’t carry significant loads or don’t face dynamic, commonly used in Japanese vehicles and equipment (Toyota, Honda, Nissan, etc.).
