Hexagon head screw DIN 933 ISO 4017, full thread, M 5x20, AF 8, stainless steel A4

Where a through bolted joint has to carry load over the entire clamping length, the hexagon head screw M 5x20 in stainless steel A4 does the work. According to DIN 933 the thread runs almost up to the 3.5 mm high head, the screw measures 20 mm. A wrench of 8 mm is all that assembly takes.

Benefits

• Non rusting material without additional coating, the dimensions of version M 5x20 follow DIN 933
• Head height of 3.5 mm keeps the build height of the joint M 5x20 low
• Short clamping lengths are possible because at 20 mm length no plain shank has to be allowed for
• Hexagon head with 8 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Stainless steel A4 for increased corrosion load such as chloride bearing surroundings
• Thread M 5 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 20 mm
