Import Flange Bolt — Buy in Bulk from Supplier in China

The Xl-b11 flange bolt from He Bei Fastener Technology Co., Ltd. is a heavy-duty fastener designed to DIN 6921 standards, featuring an integrated flange with serrated edges for load distribution and anti-rotation performance. It is manufactured from carbon steel with zinc plating (zp) for corrosion resistance, and available in standard metric sizes ranging from M6 to M24. The flange diameter and thickness conform to typical DIN 6921 profiles, ensuring compatibility with standard flange nut and bolt assemblies in industrial applications.

Carbon steel grade Q235 is the base material, with a zinc coating thickness of approximately 5 to 15 micrometers as standard for this class of fastener. The surface treatment provides moderate protection against rust in dry or indoor environments but is not rated for prolonged marine or chemical exposure. These bolts are not heat-treated and are suitable for non-critical structural applications where high tensile strength is not the primary requirement. Variants are typically produced in hex head configurations with full or partial threads, matching common industrial usage patterns.

These flange bolts are commonly purchased by manufacturers in automotive assembly, light machinery fabrication, and structural steel erection. Buyers often source them for equipment mounting, frame assembly, and pipeline support brackets where washer integration reduces component count. Packaging is typically in bulk cartons of 100 to 500 pieces, depending on size. Trade terms are generally FOB or CIF from Chinese ports, with lead times averaging 20 to 30 days after order confirmation. MOQ is not specified in the listing and should be confirmed directly with the supplier.
