scope:
This European Standard specifies the characteristics of threaded thin wall inserts, locked and with a selflocking feature achieved by deforming out-of-round the internal thread of mid length, in heat resisting steel, MoS2 lubricated.
Classification : 1 100 MPa1) / 315 °C2).
1) Corresponds to the minimum tensile stress which the insert is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class.
2) Maximum temperature that the insert is able to withstand, without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the MoS2 lubricant.
