Hexagon head screw DIN 933 ISO 4017, full thread, M 4x8, AF 7, zinc plated steel 8.8

This hexagon head screw M 4x8 is 8 mm long and made of zinc plated steel of property class 8.8. The thread to DIN 933 and ISO 4017 also allows use where the clamping length amounts to only a few millimetres. Head height 2.8 mm and width across flats 7 mm define the space the joint requires.

Benefits

• Property class 8.8 as the characteristic value for the load capacity of the joint M 4x8
• Head height of 2.8 mm keeps the build height of the joint M 4x8 low
• Short clamping lengths are possible because at 8 mm length no plain shank has to be allowed for
• Hexagon head with 7 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Zinc plated surface for assemblies exposed to moisture
• Thread M 4 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 8 mm

Applications

Bolted joints on machines with changing humidity, support frames and brackets, vehicle and trailer bodies, general assembly in maintenance.
