These oversize custom machined hex nuts were made domestically using plain low carbon steel material, to be used in a custom u-bolt/plate combination after all 3 items went through a zinc plating process. Width across the flats was set at 2″ for both the 3/4-10 and the 5/8-11 internal thread versions, and the height was at 3/4″. Parts were completed within 2 weeks of order, with an additional 1-2 weeks for zinc plating with the other two items. Our internal part number for this machined hex nut is NF-075032-B.
