The F436 High‑strength Structural Flat Washer is listed by Ningbo Steel Bolt Co., Ltd and originates from Ningbo, China. It complies with ISO standards and carries the model number F436, with a brand label of Ningbo‑bolt. The product is supplied in stainless steel, carbon steel and alloy steel, and can be finished plain, zinc‑plated or with a black‑oxide coating. Packaging options include cartons or plastic bags stacked on pallets, and the listed port of departure is Shanghai or Ningbo.
Typical industry practice for structural flat washers of this class demands a hardness of around 270 HB and a tensile strength of at least 800 MPa, which aligns with the high‑strength requirement of A325 and A490 bolt assemblies. Dimensional tolerances usually fall within ±0.1 mm for outer diameter and ±0.05 mm for thickness, ensuring reliable fit in precision joints. The supplier states a monthly production capacity of 100,000 pieces, indicating the ability to meet sizeable project demands without long waits.
Primary users include steel fabricators, bridge contractors and offshore platform builders who need reliable load distribution under high bolt preload. Ningbo Steel Bolt offers flexible trade terms and accepts T/T payments, allowing buyers to negotiate FOB, CIF or other Incoterms based on their shipping strategy. Lead times are not explicitly listed, so buyers should confirm the schedule during the quotation stage.

Confirm the exact material grade and heat‑treatment specification before finalising the order; request a mill test report that details chemical composition, hardness and compliance with ISO or ASTM standards. Verify that the chosen finish matches the environmental conditions of the intended installation, especially for offshore or coastal projects.
Logistics should be clarified early: the buyer needs to specify the preferred Incoterm, whether FOB from Shanghai or Ningbo, and confirm the expected lead time, which has not been disclosed in the listing. Payment is accepted via T/T, and the buyer should agree on currency and any required letters of credit before contract signing.
Arrange a third‑party inspection prior to shipment to validate dimensions, hardness and surface coating quality. Request a Certificate of Conformity and, if needed, a specific corrosion‑resistance test report. Upon arrival, cross‑check the packaging against the agreed terms and ensure that the inspection certificates cover the full consignment.
