Black Carbon Steel Hexagon Heavy Nuts
Wenzhou Yuanzhi Auto Parts Co. Ltd., based in Zhejiang province, China, manufactures Black Carbon Steel Hexagon Heavy Nuts. The nuts are available in material grades such as C70, 65Mn, various carbon steels, alloy steels, stainless steel and brass, with selectable grades like 4, 8, 10, AISI 2, AISI 5 or AISI 8 according to customer needs. They conform to a broad selection of international standards including GB, DIN, ISO, ANSI/ASTM, B7, BS, BSW and JIS, and are offered in sizes from M5 to M100 or custom dimensions. Finishes range from plain black oxide to zinc, nickel, chrome or hot‑deep galvanise, and the supplier can provide OEM or ODM services.
In the fastening industry, heavy hex nuts of this class typically have a tensile strength of 800 - 1000 MPa for C70 grade and a hardness of 180 - 210 HB. Standard torque values for M20 size range between 90 and 110 Nm, and a common tolerance for thread pitch is ±0.02 mm. Heat‑treatment options such as tempering, carburising, spheroidising, annealing and quenching are routinely applied to achieve the required mechanical properties. Typical packaging includes 100 to 1000 pieces per bag with labelling, or export‑standard cartons, matching the buyer’s logistical preferences.
These nuts are widely used by automotive manufacturers, machinery builders and hydraulic system integrators requiring robust fastening solutions. Wenzhou Yuanzhi lists flexible minimum order quantities and confirms ample stock or strong production capacity for timely delivery. Shipping can be arranged from Ningbo or Shanghai ports under terms such as 30 % deposit in advance and balance before shipment, with options for FOB or CIF. Prospective buyers should request the latest ISO 9001:2015, IATF 16949:2016 and ISO 1400:2015 certificates and a sample to verify finish and dimensional accuracy before placing a bulk order.

Sourcing Black Carbon Steel Hexagon Heavy Nuts from Wenzhou Yuanzhi Auto Parts Co. Ltd - China Import Guide
Importers should first confirm the exact material grade and applicable standard that the heavy nuts will be produced to. Request the latest ISO 9001:2015, IATF 16949:2016 and ISO 1400:2015 certificates together with a mill test report showing tensile strength and hardness for the chosen grade. Verify the size and thread tolerance data sheet to match the engineering drawings before finalising the purchase.
Wenzhou Yuanzhi ships from Ningbo or Shanghai ports, and buyers need to agree on an Incoterm such as FOB or CIF that suits their supply chain. The listed payment terms are a 30 % deposit in advance with the balance payable before shipment; these terms should be confirmed and adjusted if necessary. Estimating lead time based on stock availability or production schedule is essential, and the supplier indicates they can meet timely delivery given strong capacity.
Although the supplier lists ISO certifications, a third‑party inspection prior to loading is advisable to verify dimensions, thread pitch and surface finish. Request hardness testing results and a visual inspection report for coating integrity. Maintaining complete documentation, including certificate copies, test reports and packing list, will facilitate customs clearance and ensure the nuts meet the buyer’s quality requirements.
