These are custom grade 8 u bolts made using 4140 SAE grade 8 steel material with rolled 1/2-13 thread. The hardness was recorded at 36 HRC and tensile strength at 162 KSI. 5 pieces were made for our customer for testing purposes prior to a larger commitment. The inside width was set at 4.76", inside length at 8.5", and approximately 1.75" of rolled thread was incorporated on both legs. Material and heat treat certs were provided with the parts per our customer's request.
Large quantities of these custom made grade 8 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.
