Stainless steel hexagon flange bolts DIN 6921 with an integrated washer-type flange for improved load distribution and high durability. Available in A2 and A4 stainless steel for construction, machinery, automotive and general industrial use. |
DIN 6921 hexagon flange bolts feature a hex head with an integrated flange that acts as a built-in washer. The flange increases the contact surface, improving load distribution and reducing the risk of material deformation. This makes DIN 6921 bolts a strong, stable and reliable fastening solution, especially in applications subject to vibration or dynamic loads.
Stainless steel versions (A2 and A4) offer excellent corrosion resistance, making them ideal for outdoor constructions, marine environments, automotive use, machinery and structural assemblies. The integrated flange also speeds up installation by eliminating the need for a separate washer.
Typical applications:
- steel structures and metal frameworks
- machinery and industrial equipment
- automotive components (frames, engine brackets, suspension elements)
- outdoor and marine constructions
- assemblies exposed to vibration and dynamic loads
Key advantages:
- integrated flange replaces a separate washer
- better load distribution thanks to the enlarged head surface
- improved connection stability under vibration
- corrosion-resistant stainless steel (A2/A4)
- wide range of sizes and lengths for universal use
DIN 6921 flange bolts are perfect for strong, durable and vibration-resistant connections in both industrial and technical applications.
