We had 64 pieces of these custom large B7 threaded studs manufactured for our customer, with the cut and chamfer of the plain parts done domestically followed by commercial zinc + clear plating operation.  The threaded studs measured 1-1/5 - 8 X 6-1/4 and were supplied with ASTM A194 2H heavy hex nuts.  The cut and chamfer operation was relatively easy and quick but the zinc plating process took approximately 2 weeks to complete.  Rush processing is available if a quicker turnaround is ever required.
