Hexagon head screw DIN 933 ISO 4017, full thread, M 20x90, AF 30, zinc plated steel 8.8

With thread M 20x90 and a length of 90 mm this hexagon head screw to ISO 4017 covers joints that require the thread to run almost up to the head. The material used is zinc plated steel of property class 8.8. The hexagon head is driven across flats of 30 mm and stands 12.5 mm high.

Benefits

• Thread M 20 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 90 mm
• Zinc plated surface for assemblies exposed to moisture
• Hexagon head with 30 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Short clamping lengths are possible because at 90 mm length no plain shank has to be allowed for
• Head height of 12.5 mm keeps the build height of the joint M 20x90 low

Applications

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