Hexagon head screw DIN 933 ISO 4017, full thread, M 20x65, AF 30, plain steel 10.9

This hexagon head screw M 20x65 is 65 mm long and made of plain steel with black finish, property class 10.9. The thread to DIN 933 and ISO 4017 also allows use where the clamping length amounts to only a few millimetres. Head height 12.5 mm and width across flats 30 mm define the space the joint requires.

Benefits

• Hexagon head with 30 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Thread M 20 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 65 mm
• Plain surface without additional coating, the dimensions follow DIN 933 directly
• Head height of 12.5 mm keeps the build height of the joint M 20x65 low
• Short clamping lengths are possible because at 65 mm length no plain shank has to be allowed for
• Property class 10.9 as the characteristic value for the load capacity of the joint M 20x65
