PRODUCT PARAMETERS

  • High Preload Retention: DIN 6796 conical spring washers are engineered to maintain maximum clamping force and counteract structural settling or thermal expansion in bolted joints.
  • Marine Grade Corrosion Resistance: Manufactured from high-quality A2 (AISI 304) and A4 (AISI 316) stainless steel, providing exceptional durability in salt spray and chemical environments.
  • Elastic Compensation Technology: The specialized Belleville-style disc geometry acts as a heavy-duty spring to preserve tension under high axial loads.
  • Grade 70 and 80 Compatibility: Precision-engineered to work seamlessly with stainless steel property class 70 and 80 fasteners, ensuring material consistency across the assembly.
  • Global Standard Compliance: Fully certified to DIN 6796 specifications for heavy-duty infrastructure, machinery, and renewable energy applications.

Product Features & Engineering Logic

Key FeatureTechnical SpecificationOperational Benefit
Conical GeometryDisc spring shape per DIN 6796.Compensates for settling and wear to prevent the loss of bolt preload.
Material BaseStainless Steel A2 (304) / A4 (316).Non-magnetic and highly resistant to oxidation and harsh climates.
Surface FinishPlain (Bright / Passivated).Smooth, burr-free surface ensures uniform pressure distribution on workpieces.
Static LoadingStatic and heavy-duty bolting design.Ideal for secure fastening in high-vibration or temperature-variant environments.

FAQs

Q1: Can I use A2 stainless steel washers with A4 bolts?

Yes, but the corrosion resistance of the entire joint will be limited by the A2 component. For marine environments, we strongly recommend using A4 washers with A4 bolts to maintain system integrity.

Q2: Are these washers suitable for frequent dynamic cycling?

DIN 6796 is primarily for static bolting to maintain preload. For applications requiring millions of cycles (like engine valves), we suggest our DIN 2093 precision disc spring series.
