The Material Cert calls out AMS6370 as the material used. can you confirm this is correct as the spec says EN2542, EN2543 or TR391 and i can see the AMS in the TR

  Please find Genevieve’s reply :
  EN3753 require raw material conform to TR3791. This nut is an anchor nut in alloy steel. So the TR permit to use SAE 4130 per AMS 6370 ( table 2 of TR3791 enclosed highlighted in yellow ) Please find also enclosed the 1St page of AMS6370 standard which defines SAE 4130 ( highlighted in yellow )
