Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›Ningbo S&D Metalwork Co., Ltd. manufactures carriage bolts that meet ASTM A307 Grade A and SAE J429 Grade 2 specifications. The product range covers diameters from ½ inch to 1 inch, providing a common size spectrum for structural connections. Available surface treatments include black oxide, zinc plating, and other finishes to improve corrosion resistance.
The bolts are produced from carbon steel, delivering a typical tensile strength of 420 MPa for the A307 grade. For applications requiring higher corrosion resistance, a zinc‑plated finish is standard, while black oxide is typical for indoor use. Industry practice generally pairs these bolts with washers and nuts of matching grade to ensure consistent joint performance.
They are widely used in construction framing, machinery assembly, and automotive sub‑components where reliable fastening is essential. Contractors, equipment manufacturers, and OEMs in China and abroad source these bolts for bulk projects. The supplier offers flexible FOB or CIF shipping; specific MOQ, lead time and payment conditions must be verified with the supplier. Prospective buyers should request a mill test certificate to confirm compliance with the cited standards. Visual inspection for head roundness and thread integrity is part of the supplier’s quality routine.

Confirm the exact grade, diameter and surface finish required for your project before finalising the purchase. Ask the supplier for the mill test certificate and any additional compliance documents to ensure the bolts meet ASTM A307 and SAE J429 requirements. Verify that the dimensions and tolerances align with your engineering drawings.
Agree on the preferred Incoterm, such as FOB from the port of Ningbo or CIF to your destination, and clarify payment terms and lead‑time expectations. Because the supplier’s response activity is currently low, establish a clear point of contact and obtain written confirmation of shipping schedules.
Plan for a quality inspection upon arrival, focusing on head geometry, thread integrity and surface coating condition. A third‑party inspection or an in‑house dimensional check can help verify that the received bolts conform to the agreed specifications and standards.
