DIN 6796 Disc Spring Washer: High-Load Bolted Connection Solution
DIN 6796 Disc Spring Washers are conical elastic washers designed for medium to high-load bolted connections. The disc-shaped geometry stores elastic energy during compression, providing axial preload to the joint.
Key Features and Benefits
  • Conical profile acts as an active elastic element
  • Compensates for joint displacement from vibration, wear, and thermal changes
  • Maintains stable preload in demanding applications
  • Suitable for wind power, automotive, rail transit, and heavy machinery
Design and Performance Specifications
Material Options
1074 Spring Steel
51CrV4
60Si2Mn
65Mn
SUS302/304/316
17-7 PH
Inconel 718/X-750
Surface Treatments
Available treatments include phosphating, Dacromet plating, blue coating, polishing, Jumeite treatment, passivation, and Teflon coating to match service environment requirements.
Technical Performance
Hardness maintained between 420-510 HV. Maximum flattening force corresponds to 70-90% of clamping force for 8.8 or 10.9 grade bolts. M10 specification demonstrates 75.67% clamping-force retention in DIN 25201-4 transverse vibration tests.
Application and Selection Guidance
Selection Considerations: Complete joint analysis including nominal size, dimensions, thickness, working height, required load, bolt grade, installation space, and operating conditions.
Standard Size Range
Available in nominal sizes from M2 to M125. Example: M10 specification features 23mm outer diameter, 10.5mm inner diameter, 2.50mm thickness, 3.20mm height, and 22,100N force capacity.
Customization and Technical Support
Jiangsu Sunzo Elastic Technology Co., Ltd. provides both standard and custom solutions based on customer drawings, samples, or technical specifications. Customization available for non-standard dimensions, materials, and performance requirements.
OEM Inquiry Requirements
  • Nominal size and dimensions
  • Material and hardness specifications
  • Surface treatment requirements
  • Target load and working height
  • Quantity and operating environment
Engineering Note: For optimal performance, consider the complete fastening system including bolt grade, target preload, working height, material compatibility, temperature, vibration, and corrosion conditions.
