- Static load needs a flat or fender washer
- Vibration load needs spring or Belleville
Check the Surface to be Protected
- Wide OD fender washer for soft or thin material
- Standard flat washer for metal joints
Confirm Certification Requirements
- EN 10204/3.1B for traceable projects
- PMI or TPI if specified
Decide Standard or Custom Size
- Standard sizes ship from ready stock
- Custom OD, ID or thickness on request
