These custom 1"-8 grade 5 serrated hex flange nuts were produced at approximately 27,000 pieces, with zinc clear finish per ASTM B633 Type III. Full certs were provided with the parts to document surface and core hardness, material chemical properties, proof load, and certificate of conformance. 3rd party lab testing was also procured to confirm all factory documentation. The nuts were required to pass a 72,000 psi min proof load requirement and core hardness of 32 Rc max. Outside diameter was set at 1.95"-2.00" and overall nut height at .700"-.730".
Large quantities of these custom made grade 5 serrated hex flange nuts 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.
