The Order Of 1.4539 DIN912 Bolt Received From Our Familiar Canadian Customer

This time we received a 1.4539 DIN912 bolt order. When the customer does not have the required size for the inner hexagon, we will punch the inner hole with a punch. The inner hole will generally be 0.2-0.5 MM larger than the standarded hole, which is within the customer's acceptance. If it must be produced according to the standard, the process will change and the cost will increase by US$1-2.
