DIN 6796 Heavy Duty Conical Spring Washers | Hardened Spring Steel | Dacromet Coated
PRODUCT PARAMETERS
High Preload Performance: DIN 6796 (JB/ZQ 4010) conical spring washers are engineered to maintain maximum clamping force and counteract structural settling in high-load bolting.
Grade 10.9 Compatibility: Precision hardened spring steel construction specifically optimized for Grade 8.8 and 10.9 high-tensile bolt connections.
Anti-Hydrogen Embrittlement: High-performance Dacromet (Zinc Flake) coating ensures up to 1000 hours of salt spray resistance while eliminating brittle failure risks.
Dual Standard Compliance: Fully certified to both DIN 6796 and JB/ZQ 4010 industrial standards for heavy-duty infrastructure and machinery.
Space-Efficient Self-Locking: The compact Belleville-style design provides superior elastic compensation in limited-clearance installation environments.
Industrial grade DIN 6796 heavy duty conical spring washers. Made of hardened spring steel with Dacromet finish for superior preload retention and high corrosion resistance in bolted joints.

Product Features & Engineering Logic
Key Feature
Technical Specification
Operational Benefit (Trust Driver)
Conical Geometry
Disc spring shape per DIN 6796.
Maintains constant pressure by compensating for thermal expansion and structural settling.
Material Base
Premium Spring Steel (C60S / 51CrV4).
Ensures excellent elastic recovery and long-term fatigue resistance.
Surface Treatment
Dacromet (Zinc Flake Coating).
Eliminates hydrogen embrittlement risks; ideal for high-strength fasteners.
Static Loading
Optimized for static bolting.
Prevents loss of preload in heavy machinery and structural steelwork.
FAQs
Q1: What is the difference between DIN 6796 and DIN 2093 (Disc Springs)?
DIN 6796 is specifically designed for bolting applications (static or occasional dynamic loads) to maintain preload. DIN 2093 is intended for precision mechanical spring applications with frequent dynamic cycles.
Q2: Can Dacromet DIN 6796 washers be used in outdoor environments?
Yes. The Dacromet coating provides an exceptionally high salt spray resistance, making it suitable for wind power, telecommunications towers, and outdoor infrastructure.
