With thread M 8x40 and a length of 40 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 13 mm and stands 5.3 mm high.

Benefits

• Hexagon head with 13 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Head height of 5.3 mm keeps the build height of the joint M 8x40 low
• Zinc plated surface for assemblies exposed to moisture
• Property class 8.8 as the characteristic value for the load capacity of the joint M 8x40
