Laps and / or crevices on pitch and crest threads: in QTR, table 2, relevant requirements written down is 0,09 mm maximum in depth.
Since this is an ISOMJ10x1,25 bolt, maximum depth requirement should be 0,15 mm maximum as per ISO7689, table 9. This is just something to point out because if bolts have passed this test with 0,09 mm max requirement, these bolts are necessarily compliant by considering 0,15 mm maximum in depth.
No double shear test results since this bolt is too short in length. Shall we have a chance to get double shear test results carried out on EN4136H100 bolts with sufficient length? Or similar parts?
Many thanks in advance
Have a nice day

Hello Julien,
This renewal is only about a restricted scope – length 005 to 019, so without double shear test needed.
Please, let me know if you can approve this RR for EN4073-100 restricted scope – length 005 to 019.
thank you in advance,
Sebastien
Hello Sébastien,
Many thanks for clarifying.
So, we do have a length restriction from 005 to 019.
I am happy with that, so, approved from my side.
Have a nice day
Best regards
Julien
