We have been supplying these 12.9 alloy steel custom metric rolled thread screws for over 10 years to an automotive aftermarket OEM.  The alloy steel socket head blanks are ground to a smaller diameter to allow for the M14 thread to be rolled, which is a specific requirement with our customer.  We supply these parts on a revolving annual blanket purchase order to spread out the cost for our customer and lock in better pricing.  The releases are delivered the same or next day from the initiated request.
