Dear Natalia,
Good Day!
Regarding payment of INV#KH16030013-AZT, thanks for your information, after we receive the notice from our bank, will let you know!
For the length of 4.8x50 FM exceed per your attachments, all of them are within the tolerance per our drawing spec. pls see attached, red circled, we pay a lot of attention on production quality controlling on your orders, all of them are allowed- min. 49mm ~ 51mm max. May be some misconception of your QC dept. on it, would you pls re-check your QC
By the way, regarding the issue of length, our production reflected on the length tolerance of 4.8x25 & 4.8x38 is too limited, we do hope your drawing spec. can be modified as below next time.
4.8x25→24mm-25mm→24mm-25.5mm
4.8x38→37mm-38mm→37mm-38.5mm
Because, as our specialized in this kind of products which requested good drilling test, the range as red will be more sensible to guarantee on drilling speed and the length tolerance will be better on production controlling!
Look forward to receiving your comments ~
