Din6921

The DIN6921 hex flange bolt is a precision-engineered fastener designed for high-load applications requiring integrated load distribution. This product features a hexagonal head with an integrated flange, eliminating the need for separate washers. Exact dimensions include thread diameters from M5 to M30 and lengths ranging from 10mm to 120mm, with pitch values conforming to DIN standards. The bolt is manufactured to DIN 6921 specifications, ensuring consistent geometry and thread profile across batches.

Materials used include carbon steel grades 4.8, 8.8, and 10.9, with surface finishes such as zinc plating or black oxide. Stainless steel variants are available in 304 grade, offering moderate corrosion resistance. These material choices align with typical industry practices for industrial fasteners, where mechanical strength and environmental exposure dictate grade selection. The flange width and thickness are engineered to reduce bearing stress on mating surfaces, a standard design feature in heavy-duty assemblies.

This bolt is commonly used in automotive suspension systems, construction machinery, and structural steel connections where vibration resistance and joint integrity are critical. Buyers include OEM manufacturers, maintenance contractors, and industrial equipment distributors sourcing bulk quantities. Packaging is typically in bulk cartons or palletized loads, with standard export packaging. Trade terms are available on request, including FOB Shanghai and CIF destinations. MOQ and lead time must be confirmed directly with the supplier.

Shanghai Highlock Hardware Co., Ltd. is a supplier based in Shanghai with a harbor-tier trust rating. The company's profile indicates active participation in industrial fastener export markets but provides no details on factory size, workforce, or years in operation. There is no public verification of certifications, production capacity, or client list. The listing confirms the company handles DIN6921 bolts but does not state whether they manufacture or distribute the product.

Response metrics show no recorded response rate or average response time, indicating limited buyer engagement or inactive communication channels. Buyers should treat this supplier as a distributor or trader unless further documentation is provided. The absence of factory photos, certifications, or production data suggests the company may operate as a trading entity rather than a direct manufacturer.
