Import Din6916 High-Strength Round Washers — Buy in wholesale FOB from Supplier in China

The DIN6916 high-strength round washers supplied by Ningbo High Tensile Bolts Ltd. meet the DIN 6916 specification and are offered in metric diameters from M12 to M100 as well as imperial sizes 1/2-4 inches. They are manufactured from carbon steel and can be supplied with a variety of surface treatments such as zinc (yellow, white, blue, black), hot-dip galvanising, black coating, Geomet, Dacromet, anodisation, nickel plating, zinc-nickel plating or PTFE (Teflon). The listing notes that the washers are intended for high-strength applications across multiple industries.

Standard DIN 6916 washers typically have a minimum tensile strength of 1000 MPa and a hardness of 28 HRC, providing the load-bearing capacity required in automotive, machinery and electrical assemblies. Typical thickness ranges from 0.5 mm for small diameters up to 5 mm for the largest sizes, and the outer diameter follows the nominal bolt size plus a standard clearance of 2 mm. These dimensions correspond to the g6 tolerance class, which is common for precision fastener components used in demanding environments.

End users include equipment manufacturers, plant engineers and contract assemblers who need reliable load distribution under bolt heads or flanges. The supplier does not disclose minimum order quantities, unit pricing or lead times, so importers should request a detailed quotation that specifies packaging - often bulk cartons of 200 kg - and the preferred Incoterm. It is prudent to ask for material certificates and dimensional inspection reports before confirming the purchase. Direct communication through verified channels can help establish payment terms suited to the buyer's risk management.

Ningbo High Tensile Bolts Ltd. is based on Jiulong Avenue in the Zhenhai district of Ningbo, Zhejiang Province, China (postal code 315000). The company holds a harbour-level trust tier, indicating it participates in the regional verification scheme for manufacturers. Its profile shows a 0% response rate and no recent response time, suggesting that initial contact may require follow‑up.

The enterprise focuses on producing high-strength fasteners such as bolts, nuts and washers for sectors that demand rigorous mechanical performance. While the listing does not provide details on production capacity or certification status, prospective buyers can request material test certificates, hardness reports and compliance documentation directly from the factory. No further corporate background or client references are included in the public data.
