Abstract
This standard specifies the characteristics of lockbolts with protruding head, sheartype, close tolerance, in titanium alloy TI-P64001, with aluminium pigmented coating, metric series, for use in aerospace applications.
Classification: 1 100 MPa / 315 °C
In both versions, i.e. with and without pintail these lockbolts fulfill the same function when installed and are statically / dynamically equivalent.
They are intended to be used with collars to EN 4174 or EN 4175.
