Description / Abstract:
This International Standard specifies hexalobular socket
countersunk head bolts and screws with high head (full
loadability), of product grade A, and thread 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 ISO 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 than
those specified in ISO 15065.
If, in special cases, specifications other than those listed in
this International Standard are required, they can be selected from
existing International Standards, for example ISO 261, ISO 888, ISO
898-1, ISO 965-2 and ISO 4759-1.
