These are M6 metric hot galvanized flat round head bolts produced from Grade 4.8 carbon steel Q235, with a hot dip galvanized coating applied for corrosion resistance in outdoor and industrial environments. The bolts conform to a 4h tolerance standard, ensuring precision fit for structural and construction applications where dimensional accuracy is critical. They are manufactured in Hebei, China, with production adaptable to custom specifications as requested by the buyer.
The material composition of Grade 4.8 carbon steel provides a tensile strength of 400 MPa minimum, typical for general-purpose fasteners in construction, infrastructure, and machinery assembly. Hot dip galvanizing adds a zinc layer of standard thickness 45-65 microns, offering a typical corrosion protection life of 20-30 years in moderate environments. Flat round heads are designed for applications where a low-profile, flush finish is required, such as in metal-to-metal connections.
These bolts are primarily used in structural steel frameworks, bridge construction, and heavy machinery assembly where reliable fasteners are essential. Buyers typically source them in bulk for export, with packaging in cartons and pallets as per customer requirements. The supplier operates from Yongnian Five Mile Industry Zone in Handan, Hebei, with a port of shipment at Tianjin. Lead time is approximately one week, subject to order volume and customization needs.

Before placing an order, verify the exact tensile strength and coating thickness of the bolts, as these directly impact performance in corrosive or high-stress environments. Request mill test certificates or third-party inspection reports to confirm the material grade and galvanizing quality meet your project specifications. Ensure the supplier can provide documentation for compliance with international standards such as ISO or DIN.
Confirm logistics details such as lead time, which is approximately one week for standard orders but may vary for custom specifications. Discuss Incoterms, with FOB Tianjin being a common choice for this supplier, and clarify payment terms to align with your procurement policies. For large shipments, coordinate with the supplier to arrange palletized or containerized transport to minimize handling damage.
Conduct quality checks upon receipt, including visual inspections for coating uniformity and dimensional measurements to verify the 4h tolerance. For critical applications, perform destructive testing on sample bolts to confirm tensile strength and coating adhesion. Request a certificate of conformity and packing list to ensure all delivered quantities match the order and meet the agreed specifications.
