This listing supplies bolts fabricated from carbon steel to the Grade 8.8 specification, giving a tensile strength of approximately 800 MPa. The bolts conform to multiple international standards including ASTM A307, ASME/ANSI, DIN, ISO, JIS and BS, allowing use in diverse markets. Dimensions cover the standard metric thread series from M6 × 20 mm up to M24 × 200 mm, packed in bulk cartons on wooden pallets.
In addition to the plain finish, the supplier offers black oxide, zinc‑plated, hot‑dip galvanized, nickel and chrome coatings to match corrosion‑resistance requirements. Typical industry practice for Grade 8.8 bolts includes a hardness of 250 HB and a proof load of 640 MPa, which aligns with the mechanical properties of the supplied product. These bolts are widely used in machinery, heavy‑equipment assembly and structural applications where a secure grip is essential.
Buyers such as equipment manufacturers, construction firms and OEMs source these bolts for tower and pole installations, oil‑and‑gas pipelines, railway components, solar‑energy frames and metal building projects. The supplier ships the product in bulk cartons stacked on solid wood pallets and can arrange delivery under FOB, CIF, CFR, EXW, DDP or DDU terms. Payment methods include T/T, L/C and Western Union, while lead times are typically 30‑40 days after order confirmation. Exact MOQ and pricing should be confirmed directly with the supplier.

Before placing an order, importers should request the mill test certificate and material test report to confirm the carbon‑steel composition and Grade 8.8 certification. Verifying the exact finish and coating batch numbers helps ensure the corrosion protection matches project requirements. It is also advisable to ask for a sample or photograph of the square head profile to avoid mismatches.
Typical production lead time is quoted as 30‑40 days after order confirmation, but buyers must confirm the exact schedule for their required quantity. Shipping can be arranged under any of the listed Incoterms - FOB, CIF, CFR, EXW, DDP or DDU - allowing flexibility to match the buyer’s logistics network. Payment methods accepted include T/T, letter of credit and Western Union; the preferred method should be agreed in the purchase contract.
Importers are advised to engage a third‑party inspection agency to verify dimensional tolerances, head squareness and coating thickness before loading. Requesting the supplier’s compliance certificates, such as ISO 9001 or any relevant national quality system, adds an extra layer of assurance. Upon shipment, ensure the packing list, commercial invoice and bill of lading clearly state the product description, quantity and material grade to facilitate customs clearance.
