Aerospace series - Studs, coarse tolerance reduced shank, medium length threads, in heat and corrosion resisting steel, MoS2 lubricated - Classification : 1 100 MPa (at ambient temperature) / 315 °C

Scope

This standard specifies the characteristics of studs, coarse tolerance reduced shank, medium length threads, in heat and corrosion resisting steel, MoS2 lubricated.
Classification: 1 100 MPa ) / 315 °C )
The shank is reduced for better tension fatigue strength life.
