Din 6921 Flange Bolt
Din 6921 flange bolts are integrated fasteners combining a bolt and an integral flange washer, designed to eliminate separate washers and improve load distribution in high-torque applications. These bolts feature a hexagonal head and a built-in flange with an outer diameter larger than the bolt shank, typically ranging from M6 to M36 in diameter. The flange reduces surface pressure and prevents loosening under vibration.
Material options include carbon steel, alloy steel, and stainless steel, with mechanical grades ranging from 4.8 to 12.9. Grade 8.8 and 10.9 are most common for structural use. Surface finishes include plain, zinc-plated, and black oxide. The flange thickness is typically 15% to 20% of the bolt diameter, following DIN 6921 guidelines for load-bearing integrity.
These bolts are widely used in automotive suspensions, heavy equipment frames, wind turbine foundations, and railway track systems where vibration resistance and high clamping force are essential. Buyers include OEM manufacturers, maintenance contractors, and infrastructure project suppliers. Packaging is in cartons or plastic bags on pallets, with monthly supply capacity of 100,000 pieces. Export occurs via Shanghai or Ningbo ports under T/T payment terms.

Sourcing Din 6921 Flange Bolt from Ningbo Steel Bolt Co., Ltd - China Import Guide
Verify the mechanical grade and material composition before ordering, especially for high-strength variants like 10.9 or 12.9. Request material test reports confirming tensile strength, yield strength, and hardness. Confirm that the flange dimensions match your existing bolt holes and that the thread pitch is compatible with your tapped components. Do not assume standard sizes without cross-referencing drawings.
Lead time is typically 20 to 30 days after order confirmation, depending on grade and finish. Incoterms are usually FOB Shanghai or Ningbo, with payment by T/T in advance or against BL copy. Buyers should confirm whether hydrogen embrittlement relief is performed for high-strength bolts and whether packaging includes anti-corrosion protection for long sea transit.
Inspect incoming shipments for surface defects, flange integrity, and thread damage. Conduct hardness testing on a sample batch and verify flange thickness with calipers. Retain samples for quality reference. For critical applications, request batch traceability and material certification. Document any dimensional deviations or finish inconsistencies for claims or supplier feedback.
