We had 1,100 pieces of these custom metric dacromet coated u-bolts produced using 42CrMo material with heat treat hardening. The part was originally designed to be made using 17-4PH stainless steel material but a number of attempts resulted in multiple failures during bending – the material was too hard and repeatedly snapped as the tool pressed the 90 degree corners. As a result we switched to the 42CrMo material with heat treat to obtain the required hardness and strength, with a combination of the dacromet coating to achieve the corrosion resistance needed. Turned out to be a much trickier part than originally anticipated!
Large quantities of these custom made metric square 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.
