DIN603 CLASS 4.8/8.8/10.9/12.9 Carriage Bolts
The DIN603 carriage bolts offered by Ningbo High Tensile Bolts Ltd. conform to the German DIN 603 standard and are supplied in four strength classes - 4.8, 8.8, 10.9 and 12.9. They are manufactured from carbon steel or alloy steel according to the grade indicated. Dimensions cover metric diameters from M6 up to M100 and imperial sizes from 1/4 inch to 4 inch, with custom lengths available on request. Each bolt features a hex head and a square neck, matching the DIN profile.
The product line includes a wide selection of surface treatments such as zinc (yellow, white, blue, black), hot‑dip galvanising, black oxide, Geomet, Dacromet, anodisation, nickel plating, zinc‑nickel plating and PTFE coating. These finishes provide varying degrees of corrosion protection, from sacrificial zinc layers to chemically resistant PTFE. Typical tensile strengths range from 420 MPa for grade 4.8 up to 1 220 MPa for grade 12.9, aligning with industry expectations for high‑tensile fasteners. The bolts are packaged in standard bulk cartons of 500 pieces, shrink‑wrapped for moisture resistance.
These bolts are commonly used in construction, machinery, automotive and infrastructure projects that require reliable load‑bearing connections. Importers should confirm the required grade, finish and size, as well as any custom specifications, before finalising the order. Pricing, minimum order quantities and lead times are not listed and must be negotiated directly with Ningbo High Tensile Bolts Ltd.

Sourcing DIN603 CLASS 4.8/8.8/10.9/12.9 Carriage Bolts from Ningbo High Tensile Bolts Ltd. - China Import Guide
Before placing an order, importers should request the material test certificate and the DIN 603 compliance report to confirm that grade, tensile strength and finish match the specification sheet. Verifying the supplier’s ability to meet custom size or finish requirements can avoid costly re‑work and ensure that the fasteners suit the intended application.
Shipping terms, Incoterms and payment conditions are not disclosed in the listing; buyers need to agree on FOB Ningbo port or CIF Shanghai and confirm lead times directly with the supplier. Typical production lead time for standard sizes is several weeks, but exact timing depends on order volume and finish selection, so a clear schedule should be obtained before commitment.
For quality assurance, arrange a third‑party inspection before loading, focusing on head dimensions, thread pitch, coating thickness and visual finish. Request the inspection report and any relevant certification such as ISO 9001 if available. Proper documentation, including packing list and certificate of origin, will streamline customs clearance.
