Hexagon head screw DIN 933 ISO 4017, full thread, M 20x30, AF 30, stainless steel A2

Where a through bolted joint has to carry load over the entire clamping length, the hexagon head screw M 20x30 in stainless steel A2 does the work. According to DIN 933 the thread runs almost up to the 12.5 mm high head, the screw measures 30 mm. A wrench of 30 mm is all that assembly takes.
