Hexagon head screw DIN 933 ISO 4017, full thread, M 12x20, AF 19, zinc plated steel 10.9

The hexagon head screw M 12x20 in zinc plated steel of property class 10.9 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 20 mm, which simplifies short clamping lengths and through bolted assemblies. Across the flats the head measures 19 mm at a head height of 7.5 mm.

Benefits

• Head height of 7.5 mm keeps the build height of the joint M 12x20 low
• Short clamping lengths are possible because at 20 mm length no plain shank has to be allowed for
• Zinc plated surface for assemblies exposed to moisture
• Property class 10.9 as the characteristic value for the load capacity of the joint M 12x20

Applications

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

Standards and conformity

Dimensions and thread design of size M 12x20 follow DIN 933 and ISO 4017. The width across flats amounts to 19 mm to DIN and 18 mm to ISO. The material is zinc plated steel, property class 10.9.
