Import Din 6923 Flange Nuts — Buy in Bulk from Supplier in China

The DIN 6923 flange nut supplied by Ningbo S&D Metal Work Co.,Ltd is a stainless‑steel fastener that conforms to the DIN 6923 standard. It is offered in grades SUS 201, 202, 304, 304L, 316, 316L as well as carbon‑steel strength classes 4.8, 8.8, 10.9, 12.9. Sizes range from M5 to M20, each featuring a flanged collar that spreads the bearing surface. The nuts are supplied in bulk packaging suitable for export.

Stainless‑steel grades such as 304L and 316L provide superior corrosion resistance for outdoor and marine environments, while the carbon‑steel grades deliver higher tensile strength for heavy‑duty machinery. The flanged design is typical for applications where torque transmission and load distribution are critical, reducing the tendency for loosening under vibration. In the fastener industry, DIN 6923 nuts are commonly paired with metric bolts of matching size and thread pitch, and they meet the dimensional tolerances defined in ISO 898‑1. Suppliers often finish the parts with a passivation treatment to enhance the stainless surface, a practice that aligns with standard corrosion‑resistance expectations.

These nuts are widely used in construction scaffolding, automotive chassis assembly, and industrial machinery where reliable fastening is mandatory. Ningbo S&D Metal Work Co.,Ltd notes flexible minimum order quantities and offers various packaging options such as bulk cartons and wooden pallets for sea freight. Buyers should request confirmation of ISO certification, exact packaging dimensions, and payment terms before placing an order.
