I finally checked the file you sent me.
All the drawings are OK except for the ref. 2143989. The shape of the thread is not the same (please check our drawing).
I admit this last reference is difficult to produce and/or supply.
If this supplier is not able to make an exact copy of our current design, then we'll have to find an alternative with another shape.
The design he proposed in the file might be OK. Or maybe the screw used currently for India is also alright.
It may be checked by a quick trial. Please have a look an the enclose procedure.
If this test is validated, you could use this screw on all the product ranges.
For all the other references, that should not be a problem.
Please take care that :
*** Nut ref 2162005 should be Class 6
*** Screw ref2145359 should be Class 4.8
I stay available if you any other questions.
Have a nice day
