The hexagon head screw M 12x80 in plain steel with black finish, property class 10.9 joins components with a thread that reaches almost up to the head as specified in DIN 933. Load bearing thread is therefore available over the full length of 80 mm, which simplifies short clamping lengths and through bolted assemblies. Across the flats the head measures 19 mm at a head height of 7.5 mm.
