Thread profile and dimensions shall be in accordance with ISO 5855-2. Except the thread major diameter “d max.” which shall be equal to D1 min. ? 0,025.
Thus, max major diameter = 6 – 0,035 – 0,025 = 5,940 mm.
Could you please fix this in FAIR? Hopefully, actual values are below 5,940 mm.
Fillet between head and shank: A and B dimensions have been inverted.
Many thanks in advance,
Best regards,

Good Morning Julien,
The dimension of the top of the thread is not truncated at Øshaft – 0.025mm because we are in a repair dimension configuration, D1 is modified to be Ø6.3, which would give us a maximum external thread Ø of 6.240, inconsistent with an MJ6x100 – 4h6h thread according to ISO5855-2.
A & B updated.
Have a nice day.
best regards,
Quentin
Good morning Quentin,
My apologies, indeed, EN4072-063014AE is a first oversize bolt.
I forgot this particularity when reviewing dimensional report.
Thanks for these detailed answers.
Approved from my side.
Best regards,
Julien
