We supplied these 5/8 diameter custom square steel u bolts to our customer at just 2 pieces for prototype purposes. Since plain C1018 steel was used for the production the lead time was just 3-4 days, which would typically be closer to 2 weeks if hot dip galvanizing or plating process was involved. The inside width measured 14-5/8, inside depth was at 12-11/16, and approximately 4 inches of coarse thread was incorporated on each leg.
