FAQ
Q: What is the difference between a single coil and a multi-coil washer?
A: A single coil has one full turn. A multi-coil has multiple turns. The multi-coil provides a higher spring deflection range for the same load.
Q: How do I calculate the correct torque for this washer?
A: We recommend torque values based on bolt grade and joint friction. Our technical team can provide torque tables and calculation formulas upon request.
Q: Do you offer batch testing?
A: Yes, we provide spring rate testing with each batch. Test reports are available upon request.
