Hexagon head screw DIN 933 ISO 4017, full thread, M 20x45, AF 30, zinc plated steel 8.8

The hexagon head screw M 20x45 in zinc plated steel of property class 8.8 joins components with a thread that reaches almost up to the head as specified in DIN 933. Load bearing thread is therefore available over the full length of 45 mm, which simplifies short clamping lengths and through bolted assemblies. Across the flats the head measures 30 mm at a head height of 12.5 mm.

Benefits

• Short clamping lengths are possible because at 45 mm length no plain shank has to be allowed for
• Hexagon head with 30 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Property class 8.8 as the characteristic value for the load capacity of the joint M 20x45
• Zinc plated surface for assemblies exposed to moisture
• Thread M 20 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 45 mm

Applications

Steel and equipment construction exposed to moisture, conveying technology, assembly of control cabinets and housings, mounting work in covered outdoor areas.
