Blacken carbon steel DIN, UNC studs are fasteners made from carbon steel and finished with a black oxide coating. The blackened surface improves corrosion resistance and gives a uniform dark appearance. Each stud conforms to DIN and UNC thread standards, allowing compatibility with a broad selection of machinery. The studs are engineered to deliver high tensile strength suitable for heavy‑load applications.
Typical carbon‑steel grades used for these studs correspond to AISI 1020 or equivalent, providing a tensile strength of around 600 MPa. Standard diameter ranges run from M6 to M24, with lengths commonly between 20 mm and 100 mm. After heat treatment, the black oxide coating yields a surface hardness of roughly 35 - 45 HRC, which contributes to wear resistance. The coating also offers typical protection against mild atmospheric corrosion for up to two years without additional plating.
These studs are widely employed in automotive assemblies, construction frameworks and industrial machinery where secure fastening is critical. Importers can benefit from flexible minimum order quantities and bulk packaging designed for safe transport. Supplier notes that ISO and SGS approvals are available; shipping can be organised on FOB or CIF terms, but buyers should confirm all trade conditions directly with the supplier.

Before placing an order, confirm the exact steel grade, thread profile and black‑oxide finish match your engineering drawings. Ask for a material test certificate and a surface hardness report to verify tensile strength and hardness claims. Verify that ISO or SGS certificates are current and request copies for your records.
Shipping can be organised on FOB or CIF terms; discuss the preferred incoterm with the supplier early in the negotiation. Request an estimated lead time once the required sizes and quantities are finalised, as production schedules may affect delivery. Clarify the accepted payment method, with many Chinese exporters preferring L/C, T/T or open‑account after inspection.
Arrange a third‑party inspection at the dispatch port to check dimensions, thread tolerance and coating integrity. Obtain the inspection report and original certification documents before the goods are released. Keep the bill of lading, packing list and test certificates for customs clearance and quality assurance.
