Buy & Import Sae J429 G5, G8 Hex Head Bolt from Ningbo Gangtong Zheli Fasteners Co., Ltd. - Wholesale Supply

The Sae J429 G5 and G8 hex head bolts are manufactured from carbon steel with a zinc plating finish, meeting the SAE J429 specification for high‑strength fasteners. Grade G5 provides a medium carbon composition, while Grade G8 delivers a higher tensile capacity, both supplied in standard hex head form. The bolts are produced in the Jiulong Lake Industrial Zone of Ningbo, Zhejiang, and are intended for bulk export to industrial markets worldwide.

These fasteners follow typical industry dimensions, with thread sizes ranging from M8 to M24 and lengths between 20 mm and 200 mm, which covers most machinery, automotive and construction assemblies. The zinc plating offers a typical corrosion resistance of 5‑10 µm thickness, and the tensile strengths are typically around 800 MPa for G5 and 1200 MPa for G8. Such characteristics align with the requirements of structural steel connections, heavy‑duty equipment, and bridge components.

Importers usually source these bolts for OEM production lines, distributors, and maintenance‑repair operations. The supplier ships the bolts in bulk packaging, commonly using cartons stacked on pallets, but exact MOQ, price and lead time are not disclosed in the listing and should be confirmed directly. Buyers should verify the grade, finish and compliance certificates before placing an order, and discuss Incoterms and payment terms with the supplier.

Frequently Asked Questions About Sae J429 G5, G8 Hex Head Bolt from Ningbo Gangtong Zheli Fasteners Co., Ltd.
Grade G5 bolts must achieve a minimum tensile strength of about 800 MPa and a yield strength of roughly 640 MPa, while Grade G8 bolts require at least 1200 MPa tensile and 960 MPa yield strength.

Sourcing Sae J429 G5, G8 Hex Head Bolt from Ningbo Gangtong Zheli Fasteners Co., Ltd. - China Import Guide

Before confirming a purchase, verify the bolt grade, zinc‑plating condition and the applicable standards (SAE J429, DIN, ISO etc.) by requesting the relevant certification documents from the supplier. Ensure that the material test reports match the specified G5 or G8 properties and that the coating thickness meets your corrosion‑resistance requirements.

Logistics for this supplier are normally handled through the ports of Shanghai or Ningbo. Discuss the preferred Incoterm (e.g., FOB Shanghai) and confirm the expected lead time, as the listing does not provide a concrete schedule. Payment terms such as T/T are common, but they should be negotiated and documented in the contract.

Arrange for pre‑shipment inspection or third‑party testing to validate tensile strength and coating quality. Request a mill test certificate, dimensional inspection report and packaging list to accompany the shipment. These documents help assure compliance with your project specifications and simplify customs clearance.
