Seritë e hapësirës ajrore - Bulona, kokë në formë T-, toleranca e vogël, gjatësi filetimi të mesme çelik rezistent ndaj nxehtësisë FE-PM1708 (FV535), i pa veshur - Klasifikimi: 1 000 MPa/550 °C

Aerospace series - Bolts, T-head, close tolerance medium thread length in heat resisting steel FE-PM1708 (FV535), uncoated - Classification: 1 000 MPa/550 °C

Scope

This standard specifies the dimensions of uncoated T-head bolts, close tolerance, with MJ-thread, medium thread length, in heat resisting steel FE-PM1708 for aerospace applications.
Maximum test temperature of the parts is 550 °C.
These bolts are to be used in aerospace fastening systems mainly stressed in shearing force.
