22、hread diameters from M3 up to and including M10 and property classes 4.8, 8.8 and 10.9.NOTE 1 In comparison with ISO common countersunk head, the height of the head has been slightly increased in order to have screws with full loadability, in conformity with the mechanical properties specified in IS
23、O 898-1.This International Standard also specifies gauge dimensions for the control of the head dimensions.NOTE 2 Because of the increased head height, these screws are not fully interchangeable with other countersunk ISO metric screws. The assembled parts also need a slightly deeper countersink tha
