| Attribute-ID | vdi_2230_num_of_torque_transmitting_inner_interface |
| Numeric ID | 19320 |
| Value Type | PMInteger |
The number of torque-transmitting inner interfaces qM is included in the calculation of the necessary clamping force FKQ (R2) and in the calculation of the safety against sliding and shearing off (R12) of the bolt due to torsion MT.
The number of inner interfaces qM must be specified manually, in contrast to the number of transverse load transmitting inner interfaces qF, which is determined automatically by the number of plates.
