Dear Mr. Tippawan,
Good afternoon!
Thank you so much for the payment.
I will confirm with you once our bank receives the payment.
Our Technical Department reported a bolt problem to us today,
since when we were checking the bolts from our suppliers early this morning,
one bolt was found with problem, the size is 10*55, the mark is BK,
this size is used for Rigid Couplings 60.3mm and Mechanical Tee Threaded 60.3*26.9mm for your last order,
the total number of this size of bolts is 1400 nos.
We will send new qualified bolts to you for free, the courier cost will also be born by us.
You can keep the old bolts, no need to send them back to us.
We are so much sorry for all the inconvenience caused by this,
please replace the old bolts with the new bolts, so that we will have no risk on the bolts.
For any other information, please feel free to contact us at any time.
