Hexagon head screw DIN 933 ISO 4017, full thread, M 20x100, AF 30, plain steel 10.9

The hexagon head screw M 20x100 in plain steel of property class 10.9 transfers load through a thread that reaches almost up to the head according to DIN 933. The full engagement length therefore carries load even when the clamping length is only a few millimetres. Across the flats the head measures 30 mm.

Benefits

• Thread almost up to the head to DIN 933 and ISO 4017, load bearing thread over the full length of 100 mm
• Hexagon head with 30 mm across the flats for open end, ring and socket wrenches
• Head height of 12.5 mm limits the build height of the joint
• Property class 10.9 for joints loaded beyond what class 8.8 allows
• Plain surface without an added layer, so the dimensions match DIN 933 directly

Machinery and plant construction in dry environments, jig and tool making, mounting of gearboxes and bearing housings, maintenance of existing equipment.
