These are custom grade 5 u bolts made to our customer's drawing at 500 pieces.  The u-bolts were manufactured domestically in steel zinc material and heat treated to RC20.   9/16-12 rolled thread was incorporated on each leg at 1.625" in length.  The overall inside length was measured at 3.875" and the inside width at 1.565".  Material certs and heat treat certs were provided with the parts per our customer's specific instructions and the overall lead time was 5-6 weeks for the full order.

Larger quantities of these custom made grade 5 u bolts would be best supplied on a 12 month blanket purchase order basis.  The Blanket Order concept allows the customer to access the large quantity cost savings without paying upfront for the entire large quantity order. Instead we take on the burden of carrying the bulk inventory and only release the parts as needed, or often on a pre-scheduled basis provided by the customer.
