Hexagon head screw DIN 933 ISO 4017, full thread, M 12x55, AF 19, stainless steel A4

Where a through bolted joint has to carry load over the entire clamping length, the hexagon head screw M 12x55 in stainless steel A4 does the work. According to DIN 933 the thread runs almost up to the 7.5 mm high head, the screw measures 55 mm. A wrench of 19 mm is all that assembly takes.

Benefits

• Head height of 7.5 mm keeps the build height of the joint M 12x55 low
• Stainless steel A4 for increased corrosion load such as chloride bearing surroundings
• Thread M 12 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 55 mm
• Short clamping lengths are possible because at 55 mm length no plain shank has to be allowed for

Applications

Surroundings with increased corrosion load such as chloride bearing air, plants near the coast, water and waste water technology, chemical apparatus.

Standards and conformity

Dimensions and thread design of size M 12x55 follow DIN 933 and ISO 4017. The width across flats amounts to 19 mm to DIN and 18 mm to ISO. The material is stainless steel A4.
