EN2859-080:
In QTR, page 10, stress relief after tempering: AIR2133 is written. Could you please replace AIR2133 by EN2133?
Surface roughness on head bearing surface and shank: do you confirm that Ra max measured equals to 0,05 µm? (and not 0,5 µm?)
EN2859-100:
In QTR, page 10, stress relief after tempering: AIR2133 is written. Could you please replace AIR2133 by EN2133?
EN3035-050:
In QTR, page 11, stress relief after tempering: AIR2133 is written. Could you please replace AIR2133 by EN2133?
In QTR, minimum tensile strength requirement written is 16,8 kN.
This value is for MJ5 protruding head. EN3035 is a countersunk head screw with recess.
Anyway, tensile test results are compliant. This is just a remark.
Many thanks.
Best regards.

done : see new QTR ind E ( temp requirement have been updated. Nevertheless AHG was already in accordance with these values ( idem for de embrittlement )
Surface roughness on head bearing surface and shank: do you confirm that Ra max measured equals to 0,05 µm? (and not 0,5 µm?)
Done : see new QTR indE ( max is 0.4 µ)

Test has been proceeded on bolt . there was a mistake in the QTR . New QTR ind has been modiified with the right requirement . in any case AHG was in accordance with the specification . as an evidence see the screen shot copy in supplementary document where you find the requirement of 1350 daN and the different tests values ( in blue)
Thank you very much for these corrections.
Approved on my side.
Best regards.
