EN 3327:2008 PDF

Scope: This standard specifies the dimensions of uncoated double hexagon head bolts, close tolerance, with MJthread, medium thread length, in heat resisting nickel base alloy NI-PH2601 for aerospace applications. Maximum test temperature of the parts is 650 °C. These bolts are to be used in aerospace fastening systems mainly stressed in shearing force.
