DIN934 Hex Nuts Class8 Black Finish are high-strength fasteners manufactured to DIN 934 standards with a matte black oxide finish, available in sizes from M6 to M100. The Class8 designation indicates a minimum tensile strength of 800 MPa and proof load of 640 MPa, making them suitable for high-load structural and mechanical applications. The black finish is not a coating but a controlled oxidation process that enhances corrosion resistance without altering dimensions.
The base material is medium-carbon steel, typically C45 or 1045, heat-treated and tempered to achieve the required hardness. The black oxide layer is 0.5 to 2.0 micrometres thick, applied after threading and provides mild rust inhibition and reduced light reflection. This finish is common in machinery, automotive suspensions, and heavy equipment where aesthetics and moderate environmental exposure are factors. It is not a substitute for zinc plating in wet or coastal conditions.
These nuts are sourced by manufacturers in automotive, rail, and industrial machinery sectors that require high-strength fasteners with a non-reflective surface. Packaging is typically in bulk cartons of 10kg to 20kg, with custom labels available. Trade terms are negotiable, with FOB Ningbo being standard. Minimum order quantities are not specified and must be confirmed directly with the supplier.

Before placing an order, verify the material grade, heat treatment process, and mechanical test reports for each batch. Request a certificate of conformity referencing DIN 934 and ISO 898-2. Confirm that the black oxide finish is applied after threading and that batch numbers are traceable. Do not accept generic compliance claims without documented proof.
Lead time for production is typically 15 to 25 days after order confirmation, but this must be confirmed directly. Incoterms are usually FOB Ningbo, though CIF terms may be negotiated. Payment terms are commonly 30% advance with balance against shipping documents. Confirm packaging type, pallet dimensions, and labeling requirements to avoid customs delays.
Perform a pre-shipment inspection focusing on surface uniformity, absence of flaking or streaking, and correct hex width dimensions. Use a thread gauge to verify pitch and fit. Check coating adhesion with tape test per ASTM D3359. Request a packing list with batch numbers matching test reports. Retain samples for quality audit upon arrival.
