contractor in our project ask to use AM12*1000 grade 8.8 threaded rod HDG instead of HIT-V-F HDG 8.8 M12*220 and get support from HILTI Saudi Arabia reprsintative
they submit HILTI letter for precaution after cutting the rod
the letter include data (clouded in red in attached letter) and after one day the contractor get another letter after deleting one of precaution and this lead to doubt in our consultant firm about in the technical support recommendation come from HILTI KSA representative.
kindly find attached the two letters in PDF forms for your review and confirmation.
Ashraf,
Hilti employees around the globe are making their best to give you the best technically sound information we can to your question. I am sure that there is an explanation.
Unfortunately, this platform is US based and we are driven by US codes and standard, as such I can't tell you what happened.
I reached out to my colleagues in Saudi Arabia to get you an answer. He should get in contact with you rapidly.
Regards
Axel
