The DIN6921 hex flange bolt from Ningbo Yongbiao International Business Co., Ltd is a precision fastener designed for high-torque applications in automotive and machinery assembly. The product is available in carbon steel grades 4.8, 5.8, 8.8, and 10.9, with stainless steel and alloy steel variants. Thread sizes range from M5 to M16, with lengths from 10mm to 55mm. The integrated flange reduces the need for separate washers, simplifying assembly in high-volume production lines.
Material composition follows industry norms: carbon steel meets DIN 6921 mechanical requirements, while stainless steel is 304 grade with standard chromium-nickel content. Surface finishes include black oxide, zinc plating, YZP, and Geomet, each offering different corrosion resistance levels. The bolt head geometry, flange diameter, and thread profile are manufactured to DIN standards. Typical tolerances on diameter and length are ±0.1mm for precision applications.
This bolt is used primarily in automotive chassis assembly, agricultural machinery, and industrial equipment where vibration resistance and joint reliability are critical. Buyers include OEMs, aftermarket distributors, and contract manufacturers sourcing for export. Packaging is in cartons of 36x24x16cm or 36x24x12cm, with standard Euro pallets for container shipping. Lead time is 7 to 15 working days depending on order volume. Free samples are available if in stock.

Verify material grade and finish specifications in writing before ordering. Request material test reports for carbon steel grades and chemical analysis for stainless steel. Confirm that the flange dimensions match your assembly requirements, particularly for automated production lines. Do not assume sample quality represents bulk production - always request a pre-production sample for approval.
Lead time is stated as 7 to 15 days but depends on order volume. Confirm Incoterms: FOB Ningbo is likely, but clarify who pays for export customs and insurance. Payment terms are not listed - negotiate T/T or L/C terms directly. Packaging must be specified: carton dimensions, pallet configuration, and labeling for customs. Request a packing list template in advance.
Conduct a pre-shipment inspection for thread quality, flange flatness, and coating adhesion. Use a torque wrench to verify hardness compliance for high-grade bolts. Ensure the commercial invoice includes the correct HS code (7318.15) and a certificate of origin. Retain samples from each batch for quality tracking. If used in safety-critical applications, require third-party inspection reports.
