Import Carbon Steel Hex Flange Nuts Factory — Buy in wholesale FOB from Supplier in China

The Carbon Steel Hex Flange Nuts offered by Wenzhou Yuanzhi Auto Parts Co. Ltd are manufactured in a range of metric and imperial sizes, from M5 up to M20 and #6‑3/4''. Each nut carries the model reference YZ‑nuts‑014 and can be produced from carbon‑steel grades C70 or 65Mn, as well as alloy or stainless variants on request. Standard grades such as 4, 8, 10, 12 and AISI 2, 5, 8 are available, matching common fastener specifications. The nuts conform to GB, DIN, ISO, ANSI/ASTM, B7, BS, BSW and JIS standards.

In addition to the base carbon‑steel, the factory can apply finishes including zinc plating, nickel plating, black oxide, hot‑deep galvanising and plain colour, providing corrosion resistance for automotive and machinery environments. Typical heat‑treatment processes such as tempering, carburising, annealing or quenching are applied to achieve required mechanical properties. Quality is verified using calibrated calipers, tensile‑test machines, hardness testers and salt‑spray chambers, ensuring compliance with the listed standards. The production line supports small‑order samples and OEM/ODM projects, allowing custom dimensions or non‑standard designs.
