On micrographic examination, we can see a lap on crest thread.
Could you just please give the dimension and confirm that this is in line with EN3685, clause 5.5.7.2?
Just something to point out: EN3912-050022 bolt has a grip length lower than 2 times the diameter. As per EN3685, tensile test is not applicable in that case. Hopefully, tensile test results are compliant. Finally, the full length range is considered to be qualified for diameter MJ5. Is it the case?
Many thanks in advance,
Have a nice day,
Best regards.
